Keep feed rate between fz - 0.004-0.006 ipt. For cast iron machining, the bigger the C-dimension becomes, the less chattering occurs. How to Prevent Damaging Chips when Steel Machining After Improvement (Shallow Groove at Pre-Process) Chips stay in the pre-process groove. Chips are evacuated backward and chances of damaging chips are less. Make pre-process groove shallower to prevent the tool from becoming damaged from chips. Use compressed air to aid in chip evacuation. Kyocera K11
