Creating Peck Drilling Canned Cycles

摘要

With FANUC Custom Macro, you can create your own hybrid peck drilling canned cycle. Most CNC machining centers provide two types of peck drilling canned cycles: G73 performs chip breaking for malleable materials and G83 performs chip clearing for deep holes. G73 is used to break chips as holes are drilled, retracting the drill a small amount at regular intervals (every 0.1 inch or 2.5 mm, for example). G83 is used to clear chips from the drill's flutes as holes are drilled, retracting the drill completely out of the hole every three to five times the drill diameter.
