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 chances of Chips stay in the pre-process groove. damaging chips are less. Make pre-process groove shallower to prevent the tool damage from chips. Use compressed air to aid in chip evacuation. M191
