Canned Cycle Operations
Generally speaking, canned cycle of hole machining is comprised of the following six operations,
see Fig. 4-17.
Operation 1: positioning of X axis and Y axis---the cutter is rapidly located to the position of hole
machining.
Operation 2: rapid traverse to point R---the cutter rapidly feeds from initial point to point R.
Operation 3: hole machining----executing hole machining at the mode of cutting feed.
Operation 4: operations at bottom of hole----including dwell, exact stop of spindle, cutter
displacement, and so on.
Operation 5: return to point R----for continuing hole machining and safely moving the cutter.
Operation 6: return to initial point at rapid traverse rate----generally, initial point is selected after
hole machining completed.
