I've been trying to find a simple example of chamfering completely around a cross hole. One of my machines has the G12.1 functions, 2 others do not (Citizen L20's).

Can someone show me a simple program section to deburr a .250 cross hole drilled through .500 stock?

Without the G12.1 option, is there another way to do so, or any program that will calculate the Z/C movements?

Thanks!
