Aug 16 2014 as the title says the job involves making a tapered square hole in the end of a 38 round rod. distance across the flats is about 1164 leading into the hole with approx 4 degrees per side taper to about .4 deep. clearance hole for chips can go much deeper than .4 . material will probably be 303 ss or 12l14 if 303 doesn't work out.
Aug 27 2008 for production work i'm with machtool. dragging the heel on a face mill will also wear out the carbide faster. on cnc mills where the spindle is dead nuts square i would feed out in z during the cut. somewhere between .0002 and .0005inch would usually eliminate the backscratch.
