Make appropriate adjustments when chatter and/or insert chipping occurs during cutting. Use with lowered conditions when there is a big overhang and/or when pocket-cutting. Note 2) Feed rate for recommended cutting conditions table above based when axial depth of cut is ap=.098” with ARP5, and when depth of L cut is ap=.118” with ARP6. Due to the chip thinning effect when the axial depth of cut fluctuates, feed rate compensation table below shows (correction values “F”) to help calculate correct feed. Example: Feed recommended for ARP5, 304 Stainless steel, MP7130, ap=.039” is .008IPTx1.5(correction values “F”)=.012IPT. Note 3) For slotting, use 70% of the recommended feed rate listed above. For ramping, helical cutting, and plunging, use 50% of the recommended feed rate listed above. Note 4) Internal coolant is recommended in titanium alloy and heat resistant alloy machining. y Feed rate compensation table, (correction values “F”) based on axial depth of cut “ap” fluctuation.
