Hello, Excluding workpiece rigidity and machine limitations. What is the max DOC I can take with a CNMG 432 insert on OD cutting ? As of right now, machining 4140 at 500 SFM at .100 DOC ( .200 on Dia. ) at .015 per rev. with coolant at about 60% spindle load. What do you guys think ? Regards. Tom  |

| Based on what I've seen, .125 per side should be okay, much over that will likely start popping inserts now and then. You can do more with single-sided CNMM's, but only get two cutting edges.
