Cutting some holes on a bracket that will hold the DRO's reader head. This is a 3/16" 3 fl endmill, 1600 rpm, 5.4 IPM feedrate, and a 0.070" depth of cut. Little bit of chatter where it changes direction and bites into the largest amount of cutter engagement.
Love watching your videos and following your blog! Assuming that bracket is aluminum (looks like it...), I think you can definitely run a more aggressive cut. Looks like your currently taking a 0.001125 chipload. I'd try doubling or tripling your RPM & Feeds. Say, 15IPM at 4500 RPM with a similar DOC...
