2013118 i started off at 82sfm and .004 feed on my first pass at .119 deep, then the finsh pass was .100 deep at 65sfm. the cycle time was 42 minutes. i am up to 120 sfm and .004 feed and have the cycle time down to 28 minutes. i am using a 716 ball end mill same tool for finishing and roughing. it is a accupro 4 flute with altin coating.

Machining techniques are you finished yet
For semi finishing, we will run a inch finishing ball end mill as show in figure 4. the process is a z level semi finish pass at 6,000 rpm, .024 ipr, which is 144 ipm with a .03 step down. we can semi finish the complete cavity to within .015 inch of finish. this will eliminate any leftover material from the highfeed roughing mill.
