Side-Table The side-table consists of an endless frame as well as of two shelves that are let in the frame. The individual solid wood parts of the framing timbers are joined at the corners with a Mitre Joint with Dovetail Key. The shelves are let in the framing timbers by means of modified Dovetail Tenons. Not only a ridgid construction is thus created, but also, depending on the choice of material, a very attractive small piece of furniture.

? #

The use of the Mitre Joint with Dovetail Key makes a simple and problemless assembly of the endless frame possible.

Clip-Shelf For the Clip-Shelf, the crossbars are simply clipped in the sides and the shelf is already assembled.

This is made possible by the use of the Clip Tenon Joint. Because of the heavy demands on the material of this joint, the Clip-Shelf should be made out of multiplex plywood. The shelves are mortises in the sides by means of Finger Tenons, but they could also be put on drilled in shelf bearers.

C...Stool The C...Stool by Jochen Gros is one of the first pieces of furniture developed at the C…Lab at the Hochschule für Gestaltung. The C...Stool is based on the “Ulm Stool”, which was designed in the early 50s by the Swiss architect and sculptor Max Bill for the Hochschule für Gestaltung Ulm. Jochen Gros redesigned this design classic with the intention of clearly showing the effects of the CNC-production technology on the “Ulm Stool”. The influence of the production technology on furniture design is illustrated by the CNC-compatible wood joints as well as by the possibility of engraving various motives in the stool surfaces.

Meander-Shelf The Meander-Shelf was created in the course of the project l 100% C‌NC. The design aimed at developing a simple shelf that can be slotted together and thus assembled without problems nor tools, and at the same time be manufactured with as little trim waste as possible. The two vertical shelf bearers merge in such a way, that they can be cut out of one board in one go.

? #

p2

The shelves have slots that correspond to the designated vertical shelf bearers. The shelves are put in place and lock when pushed back. The better the fit of the joints, the better the stability of the shelf. The Meander-Shelf can be made out of various board materials.

C‌Frame and Panel The construction principle of frame and panel has a long tradition in furniture construction. While the framing timbers are cut out of solid wood, the panels can be made out of various materials, like board materials, synthetic materials or glass.

The use of digital wood joints as joining elements for the framing timbers gives rise to interesting design solutions and, at the same time, greatly facilitates the assembly of the frames.

? #

p2

In the case of the C‌Frame with Dovetail Key Corner Joint, the framing timbers are not directly interlinked, but joined with the use of a connector, which can be made out of various materials. This makes it possible to push the mitred framing timbers on the panel and to then fix them in place with the connectors.

? #

p3

For the second type of frame, the framing timbers are joined by means of a Halving with Elliptical Tenon. For the vertical timber frames to go through, they need to be rabbetted rather than grooved in order to take on the panel. Afterwards the panel needs to be cleated from behind.

Frame-Shelf The loose sides and shelves of the Frame-Shelf are held together and stabilised by a closed frame out of solid wood. At the corners the framing timbers are joined by means of decorative wood joints.

The joints are executed in such a way, that they can be put together and taken apart at any time without the use of tools. The sides and shelves can be made out of board material, like MDF, or out of solid wood.

Simplizissimus-Table The Simplizissimus-Table is based on a fairly simple and ingenious construction principle. All joining elements are machined together with the individual table parts. As soon as all parts are machined, the table can be put together without tools. As the assembly of the Simplizissimus-Table is self-explanatory, there is no need for written instructions.

The Simplizissimus-Table was first presented by the C…Lab at the special show l “Digital Furniture Construction … 100% CNC” on the occasion of the Interzum’97 in Cologne.

? #

p2

At the special show the Simplizissimus-Table was manufactured in only 7 minutes on a CNC-machining center, of the kind one can already find today in many cabinet-maker’s and joiner’s workshops, and with standard tools. For traditional constructions, materials and production methods, this would be unthinkable, even more so when we bear in mind that the construction principle of the SimplizissimusTable can be materialised in a multitude of variants, thus making every table a one-off piece.

Chest of drawers The chest of drawers is based on a simple board construction. Top shelf and sides are joined by means of a Lapped Finger Tenon Joint. The board shelves or bottom shelf are mortised in or through the sides by means of Finger Tenons. The Secret Finger Tenon Joint is put to use as the joining element for the drawer sides with front, back and bottom shelf.

? #

p2

The chest of drawers can be maded with various numbers of drawers. The height of the drawers can be adapted to the given requirements.

Upright furniture For upright construction, the sides of the furniture piece are fitted with two vertical and one horizontal upright. Uprights and sides are connected with tongues, so that the sides can be pushed up into the thus created U. The vertical and horizontal uprights are connected with a decorative corner joint, the Halved Dovetail Corner. As the sides are flush with the inner edge of the upright, the corners of the shelves do not need to be notched.

? #

p2

The principles of upright construction can be put to use for a number of furniture, like cabinet furniture and low tables.

Zoom-Table The Zoom-Table is designed in such a way, that its height, width and length can be proportionally enlarged or reduced. Not only the outer dimensions of the table are zoomed in the process, but all joining elements are also proportionally adapted according to the zoom factor. This means that the number of Lapped Finger Tenons, which join tabletop and legs, always stays the same. In order to manufacture the legs with as little trim waste as possible, they are abutted in the middle by means of a table joint. In addition, this table joint prevents a deflection of the tabletop when loaded.

? #

p2

The Zoom-Table can be made out of various board materials. Depending on the cutting tolerances for the joints of the Zoom-Table, the table is either simply put together or it needs to be glued.

Lapped Dovetail The Simple Lapped Dovetail can be used to lengthen framing timbers, as well as boards or panels. Due to the dovetailed tenons, the joint is secured against longitudinal tension, while the scarf prevents a perpendicular shift.

For decorative purposes, the tenons can take different shapes, e.g. like Ginkgo leaves, which can be arranged regularly or freely.

Double Lapped Dovetail As opposed to the simple version, the manufacturing of the Double Lapped Dovetail is much more costly. In exchange one gets a joint that is more durable and very decorative from both sides. The second row of dovetails is offset and this prevents an opening of the lower rabbet caused by loading, which can occur with the simple version. Depending on the precision requested of the router, the joint can be executed as detachable or glued versions.

Board Lengthening with Asymmetrical Dovetail Keys The Board Lengthening with Asymmetrical Dovetail Keys is a very decorative joint. Even though joints with dovetail keys are very old, they are hardly used in furniture construction. The dovetailed keys, which here are presented in an asymmetrical and alternating version, secure the joint against tension. The dovetail keys can be used for lengthenings as well as for width joints, or for securing cracks in solid wood boards and planks. The decorative value of the joint can be increased by the use of fine woods or other materials.

Board Lengthening with Jigsaw Keys The Board Lengthening with Jigsaw Keys clearly shows that let in loose connectors, a Jigsaw Key in our example, can take on a multitude of shapes.

They can also be arranged in various ways in order to make a durable as well as decorative joint.

When the Jigsaw Keys are used in width joints, due to the opposing main directions of shrinkage, it is recommended to keep the length of the keys to a minimum and to slightly undercut them at the ends.

Lengthening with Meander Key Unlike other loose connectors, e.g. the dovetail key, there is no traditional model for the Meander Key. The reason for this is that a key of this shape can only be made out of material that can stand longitudinal as well as cross tension. Suitable materials are, inter alia, multiplex plywood, acrylic glass or aluminium. When joining boards with a Meander Key, it is important to make sure that the wood is well dried and that there is enough material left at the inner radii of the key to withstand the tensile force.

Detachable Lengthening with Key The Lengthening with Key was designed from the start to be a detachable joint. It can be detached and relocked at any time without tools. The region around the joint is flattened on both boards and is provided with a slot. When both parts are assembled, the key is introduced into the interconnected slot and then turned. The geometry of the slot stops the key after a quarter turn. As the strain on all parts of this joint is particularly high, it is recommended to execute it in multiplex plywood.

Finger Tenons Due to the superior stability of finger tenons, it is hard to imagine traditional furniture construction without them.

Finger Tenons are the simplest of the CNC-compatible tenons. They differ from their traditional models - the European finger tenon or the Japanese “Go-mai-hozo-gata“ - through the deeper drawn cuts at the inner corners of the tenon base. The thus created jutted out tenons are characteristic for CNC-compatible manufacturing and give the joint its individual character. The width of the tenons should be at least three times the diameter of the router bit.

Lapped Finger Tenons The Finger Tenon Joint can also be executed as a lapped variant. The Lapped Finger Tenons are used wherever one of the two surfaces must not be interrupted by the joint for aesthetical or functional reasons, for example, drawer fronts or cupboard sides.

Like all other tenons, the lapped finger tenons can be made using solid wood or various board materials like multiplex plywood or MDF.

Secret Finger Tenons The Secret Finger Tenon Joint hides the tenons in its interior from curious glances. As opposed to the traditional secret tenon mitre joint, the CNC-compatible version leads to a rabbet at the front edge.

Secret joints are traditionally looked upon as the height of a cabinet-maker’s craftsmanship. Sweat and skill of the craftsman are hidden from the eyes of the world in the interior of the joint. It is said: Out of awe for his material, the cabinet-maker humbly conceals his own efforts in making a piece of furniture.

Fingertip Tenons The Fingertip Tenons are slenderer than the Finger Tenons. Ideally the width of the tenons equals the diameter of the router bit. In order to avoid that the tenons slip through, a special positioning tenon is placed at either end of each row of tenons. In the case of broader rows of tenons, additional positioning tenons can be inserted.

Due to the greater number of tenons for an equal width, the Fingertip Tenons, as opposed to the Finger Tenons, have a higher friction tight which leads to a higher durability of the joint.

Lapped Fingertip Tenons The lapped version of the Fingertip Tenons is used wherever one of the two surfaces must not be interrupted by the joint for aesthetical or functional reasons.

Depending on the degree of precision according to which the joint has been machined, we get a perfect fit joint that is durable simply by friction tight and can be detached at any time, or a joint that easily comes undone and needs to be glued. The exactness of the fit depends also on the correct tool, as well as feed and the depth of the Z-step.

Secret Fingertip Tenons The secret version of the Fingertip Tenons Joint leads to a rabbet at the front edge of the assembled joint. From a design-oriented viewpoint, this rabbet is an interesting design detail on furniture.

For traditional wood and furniture construction the rule was not to let a joint show, however complicated its execution might have been. But today, in the age of industrial furniture construction with its invisible connectors in the form of dowels and lamellos, times have changed. The demonstratively shown joints are a sign for the quality of furniture made by a craftsman.

Fingertip Tenons with Key A special form of the Fingertip Tenon is the variant with key. Its characteristic are the prolongated tenons that have a groove on the outside which perpendicular runs across the tenons. After assembling the joint, a key with a square end-grain cutting is inserted into the groove and thus secures it against tension.

There is no direct model for the Fingertip Tenons with Key. Ideas came from decorative forms of various corner locks, where surpassing tenons are employed as decorative elements.

Hammer Tenons Similar to the dovetail tenon joint, a characteristic of the Hammer Tenons is the fact that it withstands tension in one direction even without glue. This is not achieved through trapeze-shaped dovetails, but through tenons that are shouldered in their width, so-called Hammer Tenons. The best tensile strength of the joint is given when the thickness of the inner Hammer Tenon equals half the thickness of the board. A stop in the centre of the tenon base prevents the tenons from slipping through.

The Hammer Tenons can be made using solid wood as well as various board materials or three-layer boards.

Lapped Hammer Tenons Like most tenon joints, the Hammer Tenons can also be made as a lapped version. As the Lapped Hammer Tenons are durable against tension in one direction even without glue, as opposed to the Finger or Fingertip Tenons, there are particularly suitable for drawers when the front should not be interrupted for design reasons. The strength of the rabbet that covers the hammer tenons should be between 1/4 and 1/3 of the thickness of the material. If the sides are joined with the use of hammer tenons, they prevent a warping of the surface.

Simple Slotting Joint The here presented slotting joints were created when it became necessary to develop detachable joints for demountable furniture manufactured from modern wood-derived materials, like multiplex plywood for example.

For the Simple Slotting Joint, a slot is cut up to the middle of the board, at the end of the two construction elements that are to be joined. In order to achieve a high durability of the joint despite frequent variations of the thickness of the board, the slot is executed 2 mm less than the thickness of the board and a 2 mm groove is cut as a prolongation of the slot. An exact slotting together of the joint is thus made possible.

Slotting Girder Joint For the Slotting Girder Joint, the horizontal construction element, e.g. a shelf, is placed onto the tenon of the girder and pushed back in the slot that has been provided. Thus the board can not tip over and a durable joint is created that can be detached again at any time. Should the shelf be flush with the back of the girder, the self will be provided with an additional slot at its back edge.

The Slotting Girder Joint is used for example for shelves. An advantage of the joint is a quick assembly and dismantling of the shelf without tools and small connectors.

Double Lapped Slotting Joint As opposed to the Simple Slotting Joint, the Double Lapped Slotting Joint is particularly suited for wider construction elements. A slot is cut in the wide construction element from above and from below and the narrow parts are inserted into it. Depending on the lay-out of the two slots, aligned or offset, the narrow parts either butt-joint in the middle or overlap each other. When they overlap each other, like in the case presented here, the thus created shoulder can be used as a rest base for further parts.

Double Lapped Slotting Joint with Key The Double Lapped Slotting Joint with Key is useful wherever the joint needs to be secured against unintentional loosening. The two lapped construction elements are locked with a turnable key and the enclosed part is thus fixed. Around the key, the construction elements that are to be secured are flattened in a circular area and a slot is cut in it. The key, that should be made of multiplex plywood as it has to withstand great strain, is inserted in the slot created when assembling both parts and then turned. The geometry of the slot is such that the key stops after a quarter of a turn.

Finger Tenons In furniture construction, the Finger Tenons are suitable for the fitting of shelves, cross bars and footrails. These items are mortised into the side parts being either executed as an open or as a blind version.

The Finger Tenons, like the jutted out finger tenon corner joint, differ from their traditional models in the more deeply cut rebate on the inner corner of the tenon base. The width of the Finger Tenons should be at least three times the diameter of the router bit. The H-shaped mortises are, as well as the shape of the tenons, a typical characteristic of CNC-compatible manufacturing.

Fingertip Tenons with Lateral Positioning Tenons The Fingertip Tenons for T-shaped joints were developed parallel to the Fingertip Tenon Corner Joint.

It is characterised by its slender tenons and can be executed either open or blind. Ideally the width of the tenons equals the width of the router bit. It is recommended, however, to chose a one to two tenths of a millimetre larger width of the tenons, so that the router can work the tenons without problem in one go.

The outer tenons have been designed as positioning tenons in order to avoid a lateral shift of the tenons. Furthermore they prevent a distortion of the mortised parts.

Fingertip Tenons with Central Positioning Tenon The Fingertip Tenons can not only be executed with lateral positioning tenons, but also with one central positioning tenon. The latter version is mainly used when there is no great need to secure the mortised parts, e.g. cross bars and foot-rails, against torsion. If the mortised parts are broad, it is recommended to place more positioning tenons in the row of tenons.

The Fingertip Tenons can be executed in solid wood as well as board materials. When solid wood is used, one needs to pay attention to the main direction of shrinkage in the mortised parts.

Clip Tenons The use of modern derived wood products and the transfer of jointing techniques from other fields necessarily leeds to new and innovative solutions.

Clip Tenons make a detachable joint which consistently uses the springiness of multiplex plywood.

The model for this joint is found in the field of synthetic materials.

The Clip Tenons are made in such a way that both clip hooks flip back to their original position after being pushed through the mortises in the side part und thus secure the joint. The joint can be detached manually again and again by pressing together both clip hooks.

Catch Tenon The Catch Tenon Joint is a detachable corner joint.

However, unlike traditional solutions in the form of connectors made out of metal or synthetic materials, the joining elements are part of the individual pieces of furniture. The Catch Tenon Joint can therefore be put together and detached without tools, which makes it particularly suitable for packaged furniture.

When assembling, the catch is pushed through the matching latch and as soon as it is in the right position it flips back. The joint is secured against tension by the catch, while the tenons take on the arising forces.

Tenon Joint with Star-Shaped Mortise Tenon joints count among the oldest wood joints.

It is impossible to imagine furniture and carcass construction without them. They have been replaced more and more by dowel joints due to industrial furniture production. They are, nevertheless, still superior in terms of durability.

For the Tenon Joint with Star-Shaped Mortise, the tenon of the cross bar, that has beeen shouldered up to half the thickness of the wood, is placed into the vertical framing in such a way, that it is flush at the front. The Star-Shaped Mortise is a result of machining the joint on a CNC-router. The extended corners of the mortise ensure an accurate support of the rectangular tenon.

Shouldered Tenon The Shouldered Tenon combines the idea of the housed butt joint with the idea of the tenon joint.

The flattened part of the vertical frame prevents the horizontal shift of the cross bar, while its side forces are transmitted by the tenon.

The Shouldered Tenon Joint can be executed as a blind or open version. For the blind version, the tenon should be shorter than the depth of the mortise in order to avoid the tenon forcing on the mortise ground in case the wood shrinks. The Tenon Joint can also be secured against tension with the help of wood pins.

Locked Leg Framing The Locked Leg Framing is a removable carcass joint, which is used wherever legs are joint with framing rails, as for example for tables and beds.

The front and back rails have tenons, the side rails have mortises. Both rails are flattened on the outside around the tenons as well as around the mortises. When assembling the joint, the rails will be slotted together and the leg will be introduced from below in the flattened area. The rails thus resist tensile forces and, at the same time, ensure a high stability of the angle joint.

3-Dimensional Finger Tenon Joint The 3-Dimensional Finger Tenon is a joint used for three-dimensional space structures in furniture construction as well as trade fair construction.

The joint, illustrated here as a corner solution, consists of two basic elements: the outer and the inner framing timber which run parallel to each other. These two almost identical elements enable the problem-free assembly of complex structures.

Because of their geometry and the stress under which element is put, the 3-Dimensional Finger Tenon Joint should be made, if at all possible, of multiplex plywood.

Shouldered Dovetail Traditionally, lengthenings with dovetail tenons were used wherever frame woods need to be secured against longitudinal extension. In contrast to the through dovetail tenon, which is a joint solely designed to resist tension, the Shouldered Dovetail Joint also keeps the frame wood onto which the dovetail tenons are worked on from slipping through. The shoulder is generated by a parallel shift of the contour of the tenon. The maximum distance between the two contours is defined by the ratio of the tenon to the width of the frame.

Shouldered Triple Dovetail While the Shouldered Dovetail is particularly suited for the lengthening of narrow framing timbers, the here presented Shouldered Triple Dovetail with the lateral dovetail tenons has been primarily developed for broarder frames. The two lateral tenons and the opposing tenon prevent the framing timbers from twisting and improve at the same time the absorption of the lateral forces. The interplay between single and double tenons and top and undersides also adds interest to the joint from a design viewpoint.

Double Dovetail The Double Dovetail Joint combines the advantages of the dovetail tenon with those of scarf joints.

They resist longitudinal tensile forces, resist shearing stress due to the size of the fitting lateral surfaces, and are secured against perpendicular shift by the scarf. There are various versions of the Double Dovetail Joint possible.

Unlike the Symmetrical Double Dovetail, the Double Dovetail with both dovetails pointing in the same direction is very little used in traditional furniture and wood construction. The reasons for this lie in the costly manual making and are thus no longer valid for the production on a CNC-router.

Triple Dovetail The Triple Dovetail is a variant of the Double Dovetail Joint and is particularly suited for the lengthening of wide framing timbers. On the top side of the closed joint only one big dovetail tenon is visible, on the underside there are two smaller ones. They prevent the framing timbers from twisting and strengthen the joint as they shorten the length of the flattened surface. Dovetail scarfs fit in with the group of the scarf joints as well as with the group of the table joints, which can occasionally lead to misunderstandings.

Symmetrical Double Dovetail Model for the Symmetrical Double Dovetail is the Japanese “Ryo-men-ari-tsugi“. Its widespread use in Japanese wood construction is due to its simple and efficient making. For symmetrical joints, both parts are scribed and worked upon together. In the age of the CNC-router this advantage, which meant that a lot of time could be saved when joints were traditionally scribed, is not decisive any more.

Joints that were formerly a lot more costly to make can now be manufactured just as efficiently as symmetrical joints.

Double Jigsaw The Double Jigsaw is a further development of the Symmetrical Double Dovetail Joint, taking into account the possibilities that come along with CNCproduction. For example, the ability of the CNCrouter to cut so-called free shape contours. The contours can be designed on a graphics tablet and revised in a CAD-system. The condition being, that the contour can be processed with the chosen tool.

The Double Jigsaw is a very decorative joint, which being employed as a constructive detail becomes a design characteristic of the furniture piece.

Plain Scarf with Dovetail Keys Loose connectors, like dovetail keys, are used wherever joints need to be opened occasionally, or where it is not possible to loose length due to just dimensions. The loose connectors can take a multitude of shapes and be made out of different materials. Depending on the choice of material for framing timbers and connectors, the joint will show more or less. If the connectors are made out of wood, they should be made out of well dired hardwood. As the loose connentor is only inlaid, the scarf needs to be supported in order to prevent it from slipping through.

Gooseneck Mortise and Tenon Joint with Stub Tenons The gooseneck or hammer-head tenon is widely used in Japan for the executionof lengthenings with tensile resistance. The joint is characterised by the long tenon with a head at the end that is shaped like a reversed dovetail.

The Japanese “Mechigai-koshikake-kama-tsugi“ is the model for the Gooseneck Mortise and Tenon Joint with Stub Tenons. From a production point of view, it is a very costly and difficult joint. While the simple hammer-head tenon is very susceptible to torsion, the here presented gooseneck is very stable in this respect due to the two rabbets and the stub tenon.

The tenon in the shape of a Gingko leaf can not be produced with traditional tools.

The here presented joint exemplarily shows, that through the use of CNC-routers, it is possible to give wood joints a new, individual and so far unimagined shape while keeping their function.

Halved Dovetail Corner Scarf joints are next to tenon joints among the most frequently used joints in wood and furniture construction. While traditional scarf joints are considered to be not very durable, the technical qualities of CNC-compatible joinnts have been decidedly improved.

The halved dovetail corner is a corner joint that resists tensile forces. The geometry of the asymmetrical dovetail is decisive for the tensile strength.

However, it is exactly this asymmetry of the dovetail that frequently seems to render the use of this joint problematic from a design viewpoint.

Dovetail Key Corner For the Dovetail Key Corner, the framing timbers are joint with a shaped part, the dovetail key. The dovetails of the dovetail key take on the tensile stress and the mortised tenon on the underside of the key guarantees the exactness of the angle. The joint does not have to be right-angled, this type of corner joint can be used for any angle. The thickness of the key should be at most half the thickness of the framing timbers. Suitable materials for the corner key are multiplex plywood, acrylic glass or aluminium. Depending on the choice of material, the corner key will show more or less.

The dovetail keys have been completely forgotten, even though they have been used extensively in Europe as well in Japan as the “Chi-giri-iri-o-dome-tsugi“. Like the traditional models, the Mitre Joint with Dovetail Key is held together by the dovetail key. The framing timbers are tightly wedged together.

Halving with Elliptical Tenon.

A shaped tenon, here in the shape of an ellipse, can be added to a common halving to improve its tensile strength. To avoid shearing of the tenon, its geometry needs to be chosen so that it uses the maximum fibre length possible. An open or a blind version can be chosen for the tenon. Like with all frame joints, the correct choice of the framing timber is of vital importance for the quality of the joint. To avoid an opening of the joint, the main direction of shrinkage of the wood must not correspond with the width of the framing timber.

The hook that is fitted to the cross bar needs to be equipped with sufficient projecting wood to enable it to withstand the tensile stress. The hook at the cross bar also secures the joint against shifting sideways. The jigsaw tenon can take on a multitude of shapes, geometric, organic, or floral depending on to where it is applied.

Like for all frame joints, it is important that the width of the framing timbers does not surpass 10 cm.

Oval Shouldered Halving Common halvings are used wherever two timbers are supposed to cross in one plane. They are let into each other so that the top and undersides are on one level.

The Oval Shouldered Halving is not only a decorative joint, but also one that is very stable and with an exact fit when compared with the common halving. The increased fitting surface prevents a torsion of the two timbers. The oval shouldered surfaces, that can not be produced with traditional tools, are also a sign for a CNC-compatible joint.

Shouldered Dovetail Halving Halved joints are used wherever cross bars are joined to framing timbers forming a T-shape, and where a whole scarf would weaken them too much. The length of the scarf should not surpass half the width of the framing timber.

The Japanese “Ari-kake“ is the model for the Shouldered Dovetail Halving. It is a joint that resists strain in all directions. This is above all achieved by the shoulder which prevents the cross bar from twisting and relieves the load from the dovetail.

The key can be made out of multiplex plywood, acrylic glass or various hardwoods. An appropriate choice of material and colour enhances the decorative quality of the joint. To prevent the cross bar from slipping through, the joint can also be made with a shoulder.

Hooked Jigsaw Halving Table cross joints make it possible to secure connected scarf joints against tension. A precondition is, however, a sufficient length of the surpassing wood of the table.

The Hooked Jigsaw Halving is a very decorative stop lap. The circular table secures the joint not only against tension, but also against torsion and shearing of the cross bar. The jigsaw table that juts out beyond the outer contour of the framing timber is responsible for the aesthetic quality of the joint, but, at the same time, it restricts its use.

Losses when exchanging data between various CAD/CAM-programs are generally caused by the use of different entities and differently defined dxf-converters.

One problem of this new form of production, however, is the fact that the various economic fields do not progress at the same speed. Some fields, according to the expert Horst Gräber, have not even begun to make use of the potentials of the new technology. This is certainly the case where furniture construction is concerned.

The Vision of Virtual Furniture Construction

• Virtual Design Industrial design impedes the post-industrial production. This is logical: Products

that are designed for industrial manufacturing (or for manufacturing in workshops of the traditional craft trade) can either not be produced with the use of CNC-technology, or they do not make full use of its potential. Even if a design can be partly produced with the help of the new technology, it is still not suitable for the model of virtual production, as manufacturing data can not be transferred via

The Vision of Virtual Furniture Construction

• Product Publisher Theoretically, every designer could market his designs via his personal homepage. However, this entails considerable problems: How to find the product in the cyber space, and what happens when a design does not work, which means that the manufacturer simply wastes his material. There are many advantages to a collective body with quality control: the product publisher.

While industrial design needs a manufacturer, the virtual design turns to a product publisher. Virtual products will thus be published, like printed or other media. This has not been customary for design - unless we care to remember the role of the sample books for the production of the craft trade of the 18th century.

The Vision of Virtual Furniture Construction

• Techno-Factory It is easy to imagine firms that materialise the “virtual product“, that transform, for example, virtual furniture into real pieces of furniture with the help of computer-controlled technology. Techno-factories are medium-sized companies that use the latest technology, but have a work pattern that is similar to the traditional craft trade.

The designers asked themselves how the outlook on the new computer-integrated or so-called virtual production might look in detail. How will it change the design process? Who will produce the design projects? And what influence will all of it have on the form? In the course of the seminar various possibilities of future developments were sketched using theoretical models and scenarios.

FROM VISION TO REALITY In order to avoid talking theoretically about all these visions and ideas, the project group presented an introductory action in which all visitors could participate on the occasion of the exhibition C...Lab. The Offenbach Design School and the furniture store Magazin in Stuttgart featured as Product-Galleries. At both venues interested people could get an insight into the variation of designs on a monitor, demonstrated by students who took part in the project. The participants of the seminar had chosen the Ulm Stool, which had been modified, as a basic design. The Ulm Stool is a design classic which was produced with traditional jointing techniques.

However, efficient methods of production as well as increasing use of wood materials and semi-finished products during the last centuries have diminished the importance of traditional wood joints in the craft.

Not nostalgia, but a look to the future should give its stamp to the student project “Japanese wood joints ... digital“. Prof. Jochen Gros, who was in charge of the project together with Friedrich Sulzer, has described this future as “electronic craft“. A

For the first digital trial runs on screen and at the CNC-router we followed closely our traditional models. Still, the results were not simply a direct transformation of the wood joints into the new production technology: Esthetic changes were apparent. These changes were acknowledged by adapting the original names of the wood joints.

Thus the Fingertip Tenon Joint is born.

Only in few cases buying decisions are made with a view of setting a strategic course for the future, with a vision going past the every day routine. The Internet, the prototype of future information and communication systems, as well as online services, meaning data banks of suppliers, i.e. producers of fittings, are almost unknown. CNC wood machining centers are usually operated by workshop oriented variation programming, without making use of the potential of CAD systems.

The project of local customized furniture production would have to fail, if we only tried to take our current product mix over to computer-controlled production. In the same way that industrial production could only develop with production-compatible industrial design, the computer-controlled production also needs its production-compatible products.

The Data formats ....dxf

Short for drawing exchange format. DXF has been developed by the software company l Autodesk.

It is a neutral data exchange format for exchanging design-files. Most CAD/CAM-systems support importing and exporting of design-files in the DXFformat. Due to its restrictive number of describable geometric elements, DXF is mainly suited for the transfer of simple geometrical models. The efficiency of the DXF-format is directly linked to the development of AutoCad. The digital wood joints are available as 2D-contours in the DXF-format version 10 and as 3D wire frames in the DXF version 12.

The Data formats ....iges

Short for initial graphics exchange specification, an interface for the transfer of product definition data, that is independent of the software producer, and normed by ANSI, the American National Standardisation Institute. IGES allows the transfer of all currently available wire frames and surface models, as well as technical drawings. IGES transfers apart from geometric elements - e.g. point, line, circular arch, plane or free form areas - and symbolic elements - e.g. text, dimensioning or hatching - also structural elements like allocations and attributes.

It is, however, only of limited use for the transfer of complex surfaces and solid models.

The digital wood joints are available as data files in SIM-format. They have been prepared on the FBZ CAD/CAM 2D software by the MBA GmbH, and generated with the postprocessor for their use on the MBA CNC-training center FBZ 40/30. In the header of the SIM-file are given the dimensions of the stock part- U=length; V=width; W=height - with the position of the workpiece origin X, Y, Z as well as the reference point as starting point for the tools - E=cutter diameter; L=cutter length; H=total cutter length.

CNC-maschines in

wood processing CNC-machining centers have developed from CNCdrill centers and CNC-routers. They combine drill, saw and router units and allow to completely machine a workpiece on its topside and edges. At least 3 mobile NC-axes are standard today for CNCmachining centers. According to the construction of the machines, we distinguish: CNC-training machine -

• moving table machines, where the X and Y-move-

CNC-maschines in

wood processing Tool changer and clamping devices are further components of CNC-machining centers. Due to their 3 NC-axes and a limited Z-axis lift, CNC-machining centers are primarily suited for processing flat workpieces. Depending on the use, the range offered by manufacturers starts with simple training machines and CNC-machining centers for craftsmen’s workshops, and ends with machines that take over routing and drilling operations in Schematic illustration of a

is usually accomplished with neutral data exchange formats, like DXF or IGES. CAD/CAM link-ups do very rarely function straight away. They require purposeful testing of the various adjustment options of the export and import filters in both programs.

Ă&#x; #

p2

Data transfer All geometric data need to be geometrically perfect. Even the smallest deviation of transitions, e.g. between a straight line and a circle, means that the straight line is not accepted as a tangent. Geometric parts that exist twice, or geometric leftovers that were not trimmed or deleted, also cause problems generating the NC-contour. Lines used to help with constructing or dimensioning, and hatchings are considered to be geometric elements by the CAM-system, and should therefore not be passed on in the first place. Working consequently with different levels in the CAD-system not only facilitates the data transfer, but also the generation of the NC-process in the CAM-program.

Completing the geometrical data with technological data

In order to manufacture a workpiece on a CNC-machine, geometric data are required as well as data concerning the production, like the particular machine that has been selected, the fixing of the workpiece origin, the definition of the machining operations, the choice of tools with rate of feed and spindle revolutions per minute, instructions about tool changes, etc. By means of a postprocessor, which needs to be adapted to each paticular machine, the geometric and technological data are generated into a NC-program, which can then be worked by the corresponding CNC-machine.

Generating the workpiece

model in CAD Today’s trend goes towards CAD-systems with a volume-oriented presentation. This enables us to illustrate all generated objects as realistic as possible on the screen. Solid models also offer other advantages, like the problemless penetration and sectioning of geometric objects, the fading out of hidden lines, as well as the automatic generation of sections. The data of the solid model can also be used for further geometric applications, which go beyond generating a drawing. For these applications wire frames and surface models lack important information in the computer presentation of the data.

The milling on the CNC-training machine FBZ 40-30

1. The digital wood joints are designed so that they can be processed with an 8mm router bit.

Due to the cutter line compensation in the FBZ CAD/CAM 2D software, it is necessary to choose a smaller router for some wood joints. Hard-tipped router bits with a positive spiral should be used. They allow for optimal chip ejection and guarantee a good cutting quality as well as little wear and tear.

Due to their construction, the following points need to be paid attention to when machining the digital wood joints on a CNC-training machine FBZ 40-30 of the MBA GmbH (formerly Bosch GmbH):

The use of vacuum templates is recommended for small parts, or parts with free form contours. For this purpose, a groove is cut into a particle board parallel to the workpiece contour and slightly to the inside. A rubber string is then inserted into this groove. Should the frictional force, created by the vacuum, not be sufficient, sticking on sandpaper strips can increase it.

NC-programming Next to machine independent CAM-systems, workshop orientated programming systems have evolved the manuasl programming at the CNC-machine.

Workshop orientated programming systems are machine-dependent and are usually offered by the manufacturers of CNC-machining centers. They are generally based on the same programming structure, but distinguish themselves through their degree of user-friendliness and in details.

Their graphic user surface and various Macros, i.e. subprograms for certain router operations, obtain data needed by the machine in a dialogue with the user. This facilitates and shortens programming, especially when parts, that need to be produced frequently, are available as a program for variants.
