Finish pass speed and RPM? Practical Machinist
Jan 10, 2020· I am turning it about 3,000 rpm and moving about 25 ipm for roughing and finish passes. Its cutting very well but I thought maybe we can cut our time down a little, improve cutter life, and finish quality. I think I may step rpm up to 4,000 but what should I do with my roughing and finish feeds.
