Often I need to put a half circle on the end of a piece of flat stock. I tried to figure out how to do it in Intercon but had no luck. I know how to do it in Fusion 360. I would like to chuck up the stock in the vise and mill the end of the stock to form a half circle. Is there a quick way to do that in Intercon?

Supposing you have a bar of width "W", aligned along the X axis, with the right-hand end at an X position of "L" and the centerline at Y0, and you want to put a full round on that end using a cutter of diameter "D", and you don't want to bother with cutter diameter compensation, multiple passes, or lead-in and lead-out:

RAPID to X[L-W/2] Y[-1/2[W+D]] Z[clearance just above stock]
LINE to X[same] Y[same] Z[cut depth]
ARC, EP&R (end-point and radius) to X[same] Y[+1/2[W+D]] Z[same] R[1/2[W+D]] CCW
RAPID to X[same] Y[same] Z[clearance above stock]

If you want a climb cut instead of a conventional cut, then swap the Y signs (start at +, go to -) and use a CW arc.

Thank you for the answer. I will try it and hopefully don't break anything.
