Performance Testing
Medium Interrupted Machining
- Workpiece: Stainless steel (X5CrNiMo17-12-2)
- Cutting conditions: vc (m/min) = 150, fz (mm/t) = 0.1, ap (mm) = 2.0, dry
Result: Improved welding and chipping resistance
Highly Interrupted Machining
- Workpiece: Heat resistance stainless steel (1.4848)*
- Cutting conditions: vc (m/min) = 90, fz (mm/t) = 0.2, ap (mm) = 2.0, dry
Result: Controlling unexpected breakage
