Anyone with experience with this ball breaking material?
A workmate has a tough job. He has to cut a LOT of material out of a rock crusher component on a VBM. The workpiece is a high manganese steel casting. Useing the 100* angle of a 19mm CNMG roughing insert he's taking .100" DOC at .036" feed, around 150 FPM. The noise could be mistaken for a tractor being dragged upside down along a pavement. Any increase and bye-bye insert. The feed was stipulated by the boss, but apparently he was only going off the machine finish of other parts. Could've been a light finishing cut he was looking at. Any pointers as to best practice?
I was also wondering whether it would be possible to get better metal removal, or less noise , using a SC whisker ceramic insert. Any other suggestions welcome.
