General Information I Technical information for Stainless steel Guide of stainless-steel machining Stainless steels are well known for their excellent anti-corrosive property.

Excellent anti-corrosive property are due to Chromium added to these alloys. In general, stainless steels have 4%~10% content of Chromium.

Classifications & Features of Stainless steel.

Turning

General Information

>>>

1) Austenite series : One of the most general kinds of stainless steels, it has some of the best corrosion-resistance properties due to a high Cr & Ni content. A high Nickel content also makes machining more difficult. Austenite series stainless steels are usually used for can processing, chemical products and construction purposes. (AISI 303,304,316) 2) Ferrite series : It has Chromium content similar to Austenite series, but none of Ni content which results in freer machining. (AISI 410,430,434) 3) Martensite series : The only stainless steel with the ability to be heat treated. It has high carbon content but poor corrosion resistance, so it is used for parts that need higher hardness. (AISI410, 420,432) 4) Precipitate hardened series : A Chromium-Nickel alloy, it has improved hardness through low temperature heat-treatment and has superior corrosion resistance and toughness at the same time. (AISI 17, 15) 5) Austenite-Ferrite series : Though it has similar properties with Austenite and Ferrite, it has much more superior heat-resistance (approx. 2 times better). Usually used where thermal-corrosion stability is needed, such as condensers (AISI S2304, 2507).

Difficult-to-Cut Factors of Stainless steel.

1) Work-hardening property - Causes premature wear of tool and poor control chip.

2) Low thermal conductivity - Causes plastic deformation of cutting edge and fast wear of tools.

3) Built-up-edge - More susceptible to micro-chipping on cutting edges and causes bad surface-finish.

4) Chemical affinity between tool and workpiece caused by work-hardening and low thermal-conductivity of workpiece, this might generate abnormalwear, chipping and/or abnormal fracture.

Tips for Machining of Stainless steel.

K 10

1) Use a tool that has higher thermal-conductivity Low thermal-conductivity of stainless steels accelerates tool wear resulting from a decline in hardness of the cutting edge of an insert, this is due to heat piling up. It is better to use a tool that has higher thermal conductivity and with enough coolant.

2) Sharper cutting edge-line It is necessary to utilize larger rake-angles and wider chip-breaker lands to reduce cutting-load pressure and prevent build-up-edge. This will help provide better chip control to an operator.

3) Optimal cutting condition Inappropriate machining conditions like extremely low or high-speeds or low feed rates can cause poor tool life due to work-hardening of work piece.

4) Choose an appropriate tool Tools for stainless steels should have good toughness attributes, enough strength on their edge-line (cutting edge) & a higher film adhesion.

Cutting Speed’s effects When the cutting speed increases up to 20% in an application, the tool life respectively decreases down 50%. Although inversely, if the cutting speed increases up to 50% the tool life decreases down to 20%. On the other hand if cutting speed is too low (20-40m/min) Tool life shortens due to vibration.

Tapers

Feed The feed rate in turning means the progressed interval of a distance in a work piece within 1 revolution. The feed rate in a milling application means the table feed divided by number of teeth of cutter (feed rate per tooth).

- Relationship between feed and flank wear in steel turning Cutting condition Workpiece: SNCN431 Grade : ST20 Cutting speed : 200m/min Depth of cut : 1.0mm Feed : 0.2mm/rev Cutting time : 10min

Drilling

Endmills

The effects of feed When the feed rate decreases the flank wear is increases. When the feed rate is too low, the tool life radically shortens.

When the feed rate increases, the flank wear gets larger due to high temperatures, however the feed rates effect tool life less than the cutting speed. And higher feed rates improve machining efficiency.

Technical Information General Information

Depth of cut Determined by required allowances in machining a material and the capacity the machine can tolerate. There are cutting limits according to the different shapes and sizes of the insert.

The effect of a depth of cut The depth of cut does not have a big influence on tool life.

When the depth of cut is small the work piece is not cut but rather rubbed. In these cases, machine off the work hardened parts that decrease tool life.

When machining a cast skin or milling scale smaller depth of cuts usually cause chipping and abnormal wear because of hard impurities in the surface of the work piece.

Turning Relief angle Relief angle avoids the friction between workpiece and relief face and makes cutting edge move along workpiece easily.

Relationship between various relief angle and flank wear

Selection system 1. Hard workpiece / When strong cutting edge is needed - Low relief angle 2. Soft workpiece / Workpiece turning to work hardening easily - High relief angle

General Information

Affects 1. If relief angle is big Flank wear decreases.

2. If relief angle is big Cutting edge strength weakens.

3. If relief angle is small Chattering occurs .

Side cutting edge angle and Tool life Milling

As side cutting edge angle is getting bigger chips are getting thinner and wider(refer to left picture). At the same feed and depth of cut with approach angle 0 Chip thickness is the same as feed(t=fn) and chip width is equal to depth of cut (W=ap). t1 = 0.97t, W1 = 1.04W t2 = 0.87t, W2 = 1.15W

Endmills

Side cutting edge angle and 3 cutting forces Affects

Drilling

1. Big side cutting edge angle with the same feed makes chip attaching length longer and chip thickness thinner. So that cutting forces scatter to long cutting edge therefore tool life gets longer.

2. Big side cutting edge angle for machining long bars can cause bending.

Force P is scattered to P1, P2.

Technical Information

Force P is loaded.

As approach angle gets bigger Back force gets bigger and feed force gets smaller.

Endmills The affection of flute length Expression of aspect ratio

Deformation rate according to length

Aspect ratio /d Ex) 3D, 15D, 22D

Deformation rate is reaction force against external force.

Proportional to the cube of length Set flute length and overall length as short as possible The more flute the better rigidity When flute width rate is narrower drill s rigidity is higher.

Smooth chip evacuation Soft material(aluminum etc)

The path of both chip evacuation and cooling lubricant. Too big length of flute weakens drill rigidity and too small length of flute worsens chip evacuation to breakage.

thrust resistance decrease Torque increase, Burr on exit increase Soft material(aluminum etc)

low - Point angle - high low - Point angle - high low - Point angle - high

thrust resistance increase Torque decrease, Burr on exit decrease Hard workpiece(hardened steel)

While machining Margin is the part of contact between workpiece and drill s external. It prevents bending and plays guide s role .

It depends on drill size.

Cutting force decrease Poor guide

small - Margin - big small - Margin - big

Cutting force increase Good guide

Web is the part of center of drill and drill s rigidity depends on the web. Drill needs cutting edge, chisel edge, at the tip of drill because drill makes a hole at the beginning of drilling . When web thickness is big Thinning is needed to reduce cutting force.

Web thickness

Poor machinability Hard workpiece(hardened steel)

Point angle has big influence on cutting performance. It mainly depends on workpiece. In case of standard drills Point angle is generally 118.

Turning

Helix angle

Plays rake angle of cutting edge s role If helix angle increases Cutting force decreases. On the other hand If helix angle is too big Drill rigidity decreases.

Cutting force decrease Rigidity decrease Good chip evacuation Soft material(aluminum etc)

small - Web thickness - big small - Web thickness - big small - Web thickness - big small - Web thickness - big

Cutting force increase Rigidity increase Bad chip evacuation Hard workpiece(hardened steel)

Drill diameter size is getting smaller from point to shank in order to avoid the friction between drill periphery and workpiece. The decrease of diameter divided by flute length 100mm generally becomes 0.04~0.1mm. As for high performance drills and drills for hole shrinkage workpiece during operation have big back taper.

In general drills Thrust effects on chisel over 50%. Chisel edge length depends on web thickness and chisel angle. But if web is thin Drill rigidity weaken. Therefore without web thickness change Thinning makes chisel edge short or gives rake angle. In other words, Thinning makes rake angle at chisel and improves chip evacuation and decrease thrust.

Drilling Cautions Selection of drill chuck

Coolant supply

Collect chuck is favorable Because it has strong grip power

Supply enough coolant around hole entrance.

Standard cutting oil pressure : 3~5kg/ , Flux : 2~5 /min.

(General drill-chuck and Keyless chuck don t have enough grip power.)

Supply much coolant at hole entrance

General drill-chuck

Mounting drill

How to clamp workpiece

When mounting drill Periphery chattering should be within 0.02 .

Flute should not be clamped.

At high performance drilling High thrust, torque and horizontal cutting force work at the same time so that workpiece should be clamped strongly to prevent chattering.

Turning

General Information

>>>

Collect chuck

Uniformed and strong clamping is needed (Right and left, up and down)

Strong clamping is needed because bending causes chipping

Notice

Regrinding procedures Regrinding mathod (MACH drill) Point Thining

N/L, Horning

1) Preparation -Determination of regrinding areas Check the cutting edgefor damage and wear If large fracture is found, remove it by rough grinding.

K 34

No clamping flute

1) For better drill s life, small damage and wear are favorable to be reground.

2) Damage and wear size should be within 1.5 for regrinding.

3) If drill has crack, regrinding is impossible.

4) Ordering for regrinding is acceptable or purchase regrinding machine
