Hi Guys,
This is for a golf putter application. I've got a Kennametal Mill 1-10, 90* inserts with a 0.007" corner radius. Been playing around with different feeds and speeds, trying to leave grooves in the 0.005"-0.010" deep range, about 0.020" apart. I'm currently testing with only one insert on the face mill to make things simpler. I've tried various spindle speeds from 450-900, with corresponding feed rates of 12.3975ipm to 24.795ipm, with DOC's from 0.005" to 0.050". The best I can do is leave visible marks in the pattern I want, but nothing deep enough to feel. Effectively, the face mill is doing exactly what it's supposed to, just not what I want it to do. Currently testing on 6061 with MQL, but end application will be 316 and 11L17 (leaded low-carbon steel). Any advice from experience would be greatly appreciated! I've attached a picture of the desired end result, plus the insert specs. I haven't gone the fly cutter route yet, as these inserts seem to be pretty dang close to what I'd make for a fly cutter anyways (which would be totally new territory for me).
