Keep feed rate between fz=0.1 ~ 0.15mm/t. For cast iron machining, the bigger the C-dimension becomes, the less chattering occurs. How to prevent damaging chips when steel machining Before Improvement (Deep Groove at Pre-Process) After Improvement (Shallow Groove at Pre-Process) Deep Shallow Improvement of chip biting Chips are evacuated backward and Chips stay in the pre-process groove. chances of damaging chips are less. Make pre-process groove shallower to prevent the tool damage from chips. Use compressed air to aid in chip evacuation. M215
