he thermal barrier measures merely 41 x 48 x 195 mm, making it 43% smaller by volume than the preceding generation. The temperature profiling system can be used in lines with very closely spaced pins (>45 mm) and with various product basket sizes. This engineering success is primarily based on the development of a new data logger with a minimal footprint. The new DATAPAQ MicroQ18 logger connects four thermocouples via micro-miniature sockets and logs up to 32,000 readings per channel with an adjustable interval of 0.05 s or more. Its accuracy of ±0.5 °C puts it squarely in the class of the best available loggers.

MONITOR THE MINI WAVE
The new DATAPAQ SelectivePaq is a complete solution for monitoring the stability and repeatability of miniature wave selective soldering processes.
Fluke Process Instruments announces the smallest thermal profiling system designed specifically for miniature wave selective soldering processes. The DATAPAQ SelectivePaq uses four thermocouples to take measurements from the electronic assembly as it passes through the preheating and dip soldering phases. Sample intervals can be adjusted to up to 20 times per second.
T
he detailed temperature profiles enable electronics manufacturers to adjust their operations for optimum efficiency, validate the consistent quality of PCBs to customers, and prove adherence to both solder and component temperature constraints. The profiling system combines a new four-channel DATAPAQ MicroQ18 data logger with the latest micro-miniature thermocouple plugs and a low-mass thermal shield merely 20 mm high and 40 mm wide. It is therefore optimally suited to monitor the performance of machines that offer very restricted space and for use with holding frames. The complementary DATAPAQ Selective Soldering Process Sensor Array facilitates regular and frequent process stability measurements.
The logger provides a superior accuracy of ±0.5 °C and resolution of 0.1 °C. It connects up to three height-adjustable wave contact thermocouples and up to two preheat thermocouples for monitoring both process phases. The preheat thermocouples contain a top and a bottom sensor and are designed to work with IR and convection preheat technologies. The machined-from-solid aluminum logger case and user-replaceable rechargeable battery pack ensure a long operational life and lowest ownership costs. The system is supplied with the full DATAPAQ Insight Reflow software. Data analysis includes maximum slopes, maximum temperatures, and wave contact times. The software enables data export to other Windows-compatible programs. MORE INFORMATION

FOR TEMPERATURES DOWN TO -60°C Explosion-protected, robust and resistant to cold: new series of Ex position switches.
O
ffshore industry knows no fewer than four factors which make extreme demands on switchgear. There is a risk of explosions; switches are exposed to high levels of mechanical wear and tear; the environment is corrosive; and it can be very cold. The steute business unit “Extreme” has developed the position switches in its Ex 97 series for precisely this requirement profile – and will be presenting them at the SPS IPC Drives.
MORE INFORMATION
These position switches, with dimensions to DIN EN 50047, have been tested and approved according to ATEX and IECEx for use in gas Ex zones 1 and 2, as well as dust Ex zones 21 and 22. They can be used in temperatures as low as -60°C, which is very demanding on housing construction and sealing. For example, it must be guaranteed that the switchgear's high protection class (IP 66) will be maintained in these subzero conditions at all times, even after a 7-Joule impact test. For this reason, the stable housing is manufactured from high-quality fibreglass-reinforced plastic. The sealing of the housing cover is completely vulcanised, while the sealing of the plunger features a redundant sealing system, comprising an external sealing cuff able to withstand low temperatures and an internal Teflon sealing ring. 18 | Industry Asia Pacific | January 2017

The sealing materials have been cleared by their manufacturers for temperatures down to -95°C, and the lubricants down to -75°C. There is therefore a sufficient “tolerance” to the steute-approved temperature of -60°C. This gives users the certainty that the new position switches will work reliably even in truly extreme ambient conditions. Due to a comprehensive range of actuators (plunger, roller plunger, roller lever, parallel lever, turning lever, adjustable turning lever, push button…) and their compact dimensions, the Ex norm switches are very versatile and easy to integrate in a surrounding construction. They are available with slowaction or snap-action and, as an added bonus, earthing and potential equalisation are superfluous because of the protection-insulated plastic. This set of features in the Ex 97 series makes it a good example of the “Extreme” switchgear developed by steute. It is suited not only to applications in the chemicals industry and energy technology, but also e.g. for position monitoring of flaps and valves in plants of the oil and gas industry (offshore and onshore), as well as on ships travelling through the Arctic. www.steute.co.uk

COMPACT BIDIRECTIONAL DATA MEMORY MODULE IO-LINK MEMORY MODULE
Balluff offers a compact, bidirectional data memory module for tight mounting spaces. The compact memory module with IP 67 protection is just 34 x 16 x 8 mm in size and can be used as a memory storage device on interchangeable units such as milling heads on gantry type machining centers.
T
his means the assemblies can carry their actual operating data along with them. With the following advantage: When a machine is changed, all the data such as the number of use cycles, shock and vibration values or lubrication and oil change intervals are directly loaded. The work required to install and parameterize the module is minimal. Only a single standard cable is required for stable, fault-free, bidirectional data transmission between the milling head and controller. The cable is connected to the milling head interface in the system ring. Data transmission is noise-immune as well as resistant to EMC effects. The module can hold a total of 14 segments of 64 bytes each.
Machine operators will profit from the fact that when a milling head is switched from one machine to another, all the identifying and usage data will be automatically copied and loaded from the milling head memory into the NC controller through a cable. When maintenance or repair work is needed, the service personnel can read out all the data from the memory chip on a PC or laptop and update it as needed. This gives the plant operator continual and transparent information about the current status of the milling head. Once again IO-Link proves to be a key technology for highperformance, space-saving Industry 4.0 concepts. www.balluff.co.uk MORE INFORMATION 18 | Industry Asia Pacific | January 2017

“ESPRIT 2016’s ProfitTurning™ toolpath maintains consistent cutting forces and chip loads, allowing cutting speeds to be significantly increased. By employing trochoidal turning and controlled engagement techniques, the ProfitTurning™ toolpath also reduces vibration and residual stresses, which in turn makes it particularly well-suited to thin walls or hard materials, especially super alloys. The net result is significantly reduced cycle times and maximized productivity.” 18 | Industry Asia Pacific | January 2017

Physics-Based Cutting Engine ESPRIT 2016 uses a physics-based cutting engine which provides the foundation for the technologies such as ProfitTurning™. While traditional cutting strategies consider only the geometry of materials, ESPRIT 2016 taps deeper into the science of how different industrial materials can be cut in the most efficient ways possible. Its new toolpath technology uses the principles of physics to formulate unique strategies for each cutting challenge. To do that, ESPRIT 2016 inputs all relevant factors in the toolpath algorithm such as tool material, tool shape, workpiece material, tool speed, feed rate, chip deforming, chip load, machine tool power, acceleration and deceleration. This helps establish complete control of the cutting environment, allowing for optimal cutting everywhere along the toolpath.

TEN SIMPLE STEPS TO PEAK PERFORMANCE AND PRODUCTIVITY
Figure 1: NEXT STEP – total integrated production model
All machining shops face the same task: converting raw material into finished workpieces. The products must be machined to the specified level of quality, completed in the required quantity and delivered within the desired amount of time. Sustainability considerations and environmental issues must be resolved as well. To remain competitive and profitable, shops continually seek the most economical and productive ways to accomplish their work.
T
he ultimate example of those process improvement efforts today is what is called in Europe “Industry 4.0” – strategy and tactics that integrate state-ofthe-art data acquisition, storage and sharing technologies into the manufacturing process. Industry 4.0 is presently the top level of manufacturing evolution, requiring strong management commitment, specialised personnel and significant investment. Figure 1: NEXT STEP – total integrated production model MORE INFORMATION
Unfortunately, shops that lack the extensive resources of global industrial giants such as General Electric or General Motors may feel that productivity improvements are out of reach. However, simple, cost-effective analyses and actions can have a large positive effect on the productivity of small to medium-size operations. In fact, before investing in new computers, robots or personnel, any shop, large or small, should perform basic process analysis and organise current 18 | Industry Asia Pacific | January 2017

equipment and practices. The truth is that computerisation of disorganised shop operations results only in computerised disorder. Three phases and ten simple steps Organisation of shop practices begins by viewing the production process as three phases. First is a selection phase, involving choices of cutting strategy, tools and cutting conditions. The next phase is collection, in which the selected tools and strategies are grouped together in a machining process. Realisation is the third phase and puts the process into action. In a large number of cases, the results of phase three fails to meet expectations, and certain steps are needed to bring reality in line with preparation. The steps can be technical in nature, such as seeking ways to moderate cutting forces, or economic, including actions to reduce costs. Fortunately, there are ten simple steps that will enable a shop to analyse

and improve its metalworking operations. They are as follows. Intelligent budget control A common approach to budgeting in metalworking operations is to acquire every element of the process at the lowest price possible. However, it is best not to base tool selection on price alone. Before discussing prices, a shop should consider the desired end results. If a tight-tolerance, top quality part is the goal, more-expensive precision tooling will be required to machine it. Figure 2: Different selection criteria for tooling The cost of struggling with bargain tools to achieve high part quality and producing unacceptable parts will exceed the expense of higher-priced tooling. On the other hand, when quality demands are less stringent, a portion of the capabilities of high-precision tools will be wasted. Recognising the ultimate goal of the process is the first step in cost-effective purchasing decisions.
Figure 3: The two-step model for cutting condition selection Nonetheless, simply reducing cutting parameters overall is not an intelligent way to deal with process constraints. For example, changes in depth of cut have a greater effect on the consumption of machine power than changes in feed rate. The combination of decreasing depths of cut and increasing feed rate can improve productivity within the constraint of limited machine power. Tool application rationalisation Considering the massive number of tool geometries, sizes and materials available, the possible configurations of metalcutting tools are practically endless. Machine shops typically make tool application choices one operation at a time, choosing a specific tool to create a certain feature on a part and then picking another tool to machine another different feature.
MORE INFORMATION
Intelligent handling of constraints Real-world metalworking operations, as opposed to theoretical discussions of metalworking theory, are bound by practical constraints that include machine power and stability and customer demands regarding dimensions and surface finish quality. Cutting conditions can be varied over a wide range, but the effects of different combinations of
parameters on cutting forces and surface finish may limit some choices.

Figure 4: The total offer for tooling is enormous – rationalisation is the key
Figure 4: The total offer for tooling is enormous – rationalisation is the key In an example case, two separate tools would be used to turn a shaft and produce a wide groove with two square shoulders. Specifically, one tool turns the shaft to the desired diameter and cuts one shoulder and the width of the groove, followed by a second tool that cuts the other shoulder. Each tool is programmed and optimised separately, representing separate programming and administrative costs. A contrasting tool selection strategy is to develop a highlyspecialised custom tool that can create multiple features in one machining pass. The strategy is convenient but the design and manufacturing of special tools is expensive. Between the two extremes is an approach that utilises a standard tool engineered to perform more than one operation (multi-directional tooling). A perfect example of this approach is a Seco’s MDT tooling. MORE INFORMATION
The tool’s features enable it to turn the diameter, plunge in to create one shoulder, move across the shaft to cut the groove, then withdraw to form the second shoulder. Even if such a multidirectional tool does not operate at the optimised cutting parameters of the two separate tools, the savings in tooling, programming, tool change time and inventory costs make the multidirectional tool the preferred choice. 18 | Industry Asia Pacific | January 2017
16
Complex workpiece approach (group technology) Comparable to the technique of applying tools that combine two or more operations, a shop can choose tools that are capable of creating similar features across a range of workpieces. A shop may machine a wide range of different workpieces, but the workpieces will share common features such as holes, slots and milled surfaces. To expedite the machining of complex parts, a shop can view similar features as a group and choose a tool optimised for a certain operation, such as holemaking, that is repeated on different parts. The optimised tool maximises productivity and also reduces cost when considering the engineering time that goes into repetitively programming tools for each separate part. The group technology approach also helps reduce tool inventory. Achieving minimal functional workpiece quality Although the concept initially may seem strange, shops must realise that it is necessary to achieve only the lowest possible workpiece quality that meets customer specifications and functional requirements. There is no need to exceed those requirements. If a part tolerance is 5 microns, achieving 3 microns is a waste of time and money. Higher quality tooling and more precise operating processes will be required to achieve the tighter tolerance. But customers will refuse to pay for such unrequested higher quality, and the job will be a money-losing proposition for the shop.
NEWS Figure 5: Total quality of a finished workpiece is influenced by a big number of elements
Figure 6: Cutting tools wear out due to different phenomena
Figure 5: Total quality of a finished workpiece is influenced by a big number of elements Some quality issues, such as burrs, obviously must be resolved. And there are situations where minor cost considerations are irrelevant – tool cost differences of a few Euros or cents are meaningless when compared to the value of a large titanium aerospace component the tool will machine. To maximise cost efficiency, a shop should tailor production quality to the functional and quality requirements of the workpiece. Predictive tool maintenance Traditional tool maintenance is reactive. When a tool wears out or breaks, it is replaced. That approach, however, generates costs beyond those of the tool itself, including manufacturing process downtime and possible damage to the workpiece. Preventive tool maintenance is a step beyond reactive maintenance. Figure 6: Cutting tools wear out due to different phenomena
MORE INFORMATION
The useful lives of even identical tools usually vary above and below an average length of time. Preventive tool maintenance is based on replacing the tool before it reaches its shortest expected working life to be sure that the change is made before the tool wears out too much or breaks. That approach, however, wastes tools with a tool life that is at or above average.
A relatively new approach, based on tool life modeling, uses computer calculation and simulation to provide predictive data on tool deterioration and to indicate when replacement is due. At a somewhat greater expense, use of sensors can further fine-tune the results by tracking tool wear in real time. Use of predictive tool maintenance has the potential to reduce tooling costs by 15 percent, 20 percent or more. >>> 18 | Industry Asia Pacific | January 2017

Figure 7: Productivity and cost efficiency can be achieved through different roads
Tool inventory control When dealing with the second – collection – phase of metalworking production, it is important to note that tool inventory control is different than tool management. Tool management refers to organising an existing tool inventory and making it available for production. For that task, a variety of automated tool management systems is available. Tool inventory control, on the other hand, is an effort to rationalise and consolidate the number of tools a shop possesses to focus on what is really needed. If tools are not rationalised before being loaded into an automated tool dispenser, the result is simply automated disarray.

Practical work analysis In his 1907 book “On the Art of Cutting Metals” American engineer and work analysis pioneer Fredrick Winslow Taylor noted that some of the activities in a workshop, such as milling a surface, clearly add value to a workpiece. On the other hand, he noted that many activities that are necessary for the production of a finished workpiece do not directly add value. These include e.g. fixturing the workpiece on the machine or writing the machining program. Taylor said that non-value-adding tasks should be completed as fast as possible and in a way that minimise their effects on the total costs of production. Automation can accomplish tasks such as part loading and fixturing and save time and money. 18 | Industry Asia Pacific | January 2017

Conclusion: phase 4 and STEP education As manufacturers of any size utilise the ten simple steps to improve their operations, a fourth phase of the production process involves ongoing internal education. The goal of that education is to ensure shop personnel realize solutions to productivity issues do not always necessitate huge investments, high technology and expanded workforces. The lessons learned while improving an operation or a family of operations can be reapplied and expanded to include similar situations throughout an entire shop. These lessons can be supplemented with organised education such as the Seco Technical Education Program (STEP), a well-developed and practical program designed to familiarise users with the latest tooling systems and techniques. Combined with practical experience in process analysis and improvement, education is the key to establishing a culture of problemsolving and process improvement that will result in ongoing manufacturing success.

When performing practical work analysis, costs may be obvious, hidden or overlooked. The factors affecting the total cost of converting raw materials into a finished workpieces can generally be grouped into eight categories. The categories include tools and tooling systems; workpiece materials; processes and process data; personnel and organisation; maintenance; special factors; peripheral equipment; and various random factors. Processing time is the most obvious cost factor, and it includes machining time as well as the time spent in machine and tooling setup, work handling operations and quality inspection. It is clear that a planned amount of downtime is necessary for setup and workhandling, but a less apparent subset of processing time is unplanned work stoppages resulting from unanticipated tool deterioration, chip problems and inconsistent quality. Unreliable machining processes that produce poor quality or rejected parts, broken tools, damaged workpieces and systems problems needlessly increase process times and expense. The factors at the forefront, such as machining time and scheduled tooling replacement, may contribute less to overall processing time than the effects of operator errors and system anomalies. Engineering – consisting of general, geometric (programming) and technical (selection of tooling and machining parameters) activities – is often overlooked as a contributor to overall production time. Part programming represents a significant portion of engineering time, but a large amount of engineering activity is also consumed in technological issues such as tool selection and choice of machining parameters.
