I have a bridgeport series II interact II heidenhain tnc151a programming g-code in inches I'm trying to make a 2 inch diameter boss .750 deep in aluminum 6061 I 've been able to do it but I had to go and edit the z depth everytime I got the job done but for the next time around I need to know a more efficient way I'll show you how I've been doing it. The center of the boss is the origin. Cutter radius .313
N10 G00 G90 Y0 X-1.313 z+.1
n20 G01 z-.1 F100
N30 G90 I0 J0 G12 H-180 F200
I let it run go edit the -z and let it run etc...
Take it easy on me I'm a newbie on programming and this is all I could do to get it to work I wanted to set up a label and have a G91 for the -z so everytime it looped around it would increment down a .100 at a time I had no luck at that says I was missing a tool call
