I have an idea and I wanted to bounce it off some of wiser minds than mine.
Ok I got a problem job going right now with some 316L SS. The issue is I am going through tooling at a prodigious rate. The material is 1/4" x 3/4" sheer cut 316L and I am going through tools at the rate of about 2 per day. I am running a 3/8" 5 flute endmill made for SS .125 doc .015 woc 5500 rpm 90 ipm. Those are the same parameters that I run on all my other (extruded) 316 SS jobs and that endmill typically lasts 3 weeks or 150-250 parts. I think the difference between my current job where I'm getting 30-40 parts and other 316 SS jobs is the material. Specifically the fact that its sheered from a plate. I think the sheering process is work hardening the stock and killing my tools.
Does this sound right to anyone or am I just crazy?
