Rules For Bolt Pattern Canned Cycles:
1. The tool must be placed at the center of the bolt pattern before the canned
cycle execution. The center is usually X0, Y0.
2. The J code is the angular starting position and is always 0 to 360 degrees
counterclockwise from the three o’clock position.
Looping Canned Cycles
The following is an example of a program using a drilling canned cycle that is
incrementally looped.
Note: The sequence of drilling used here is designed to save time and to
follow the shortest path from hole to hole.
