Material Material Characteristics
Carbon Steel, Alloy Steel and Tool Steel 36-48 HRC: • Higher carbon content
• Higher chrome, nickel, and moly content
• Tough material to machine
• Abrasive
• Difficult to break and control the chip flow
• The material surface will harden when machined at high speed
• Good surface finish
Ferritic, Martensitic, and PH Stainless Steel under 48 HRC: • Brittle
• Stringy chips
• High cutting force
• The material will harden when machined at high speed.
Austenitic Stainless Steel: • Becomes gummy under machining operations due to nickel content
• Very difficult to machine in soft conditions
• Very difficult to machine at a small depth of cut
• Develops a tough string of chips that are difficult to control. Forms a build-up on the insert tip
• Low thermal conductivity results in excess heat at the insert tip
• Material surface will harden due to high chromium content
Ductile and Malleable Cast Iron • Very difficult to machine
• Small depth of cut
• Spherical form graphite makes machining difficult
• The carbide concentration creates hard spots
• The material structure is not uniform
• The crater wear and flank of the insert makes machining difficult
• The insert tool life is less than gray cast iron
Gray Cast Iron • Flake form of graphite makes machining easy
• Contains scale, inclusions and sand in the surface
• The material will break easily on the end of the cut
• Tendency to chatter and vibrate on thin wall section
• Chucking and rigidity of the workpiece is extremely important to minimize distortion, to achieve a good finish and close tolerance.
