Hey everyone, I'm trying to figure out how to source raw material for a Ti-6Al-4V part I'll be machining. I'd like to have as many of the inner features and inner contour rough cut on a waterjet or fiber laser cutter to reduce on cycle time. My goal is to have all features cut with 10 thou stock to leave to be cleaned up with a finish pass in our mills. Due to small internal radii and better cut tolerances, I'd prefer to stick with fiber laser. My main concern is warping and the heat affected zone from the laser. I've read several research papers on the affects of laser cutting on 6AL-4V, but none of them mentioned the affects on machining properties. Has anyone had experience with this? For reference, my part is .160" thick so I'll most likely purchase a sheet that's around .210" thick.
