So I'm drilling 6061 bar stock on a turning center on the centerline with a .625 diameter drill to a depth of 1.25". Drill point angle 140 and solid carbide drill. Hole looks beautiful, no issues there. Then I come behind the drill with a .375" diameter solid carbide boring bar. I need to bore to .827" diameter, .750" deep. I've reduced the DOC to .030" just to see if light cuts would help, but no it doesn't. I'm getting this folded piece of metal in the back of the hole that the next pass grinds against and can't figure out why I'm getting this. See the picture I've attached and the simple code is something like:
G00 X.685 Z.1
G01 Z-.750 F.003
X.600
G00 Z.1
X.745
G01 Z-.750 F.003
X.600
G00 Z.1
X.805
.....AND SO ON UNTIL A .827 DIAMETER IS REACHED
