7 Programming: Canned Cycles, sub-programs



Use the draft pocket milling cycle to machine a draft angle on the 
outer contour of a pocket. The tool must be positioned at the center 
point of the lower-left corner radius, at the bottom of the draft 
pocket, prior to running the draft pocket cycle. This is where the 
machining begins. You can program a rectangular pocket cycle to 
mill out an initial pocket prior to the draft angle pocket block if 
desired.
