we are turning a broze part and are un able to get the chips to break. this material is soft and we have tried several inserts, feeds, feeds. we are turing this part on a nomura swiss type machine. right now we have spindle speed at 8000rpms and a feed rate from .002-.012 with no luck at breaking a chip, they curl and wrap around the part. this makes it hard to pick off and knurl. any suggestions would be gratly appreciated.

thanks

chuck
