A Hole Is Drilled In The Center Of A Bolt Hole Circle Or Arc

A hole circle or arc must have two lines of code. The first line gives the drill/tap parameters. The L0 code prevents the drill hole in the center. This occurs before the canned cycle starts. Remove the L0 code if you want the hole. This example peck drills 6 holes in a 60-degree arc pattern. A hole is at each 10-degree increment. Each hole has a 3" radius and no center hole.
