X, Y Plane Obstacle Avoidance In A Canned Cycle:
There is also a way to avoid an obstacle in the X, Y plane during a canned cycle by placing an L0 in a canned
cycle line, we can tell the control to make an X, Y move without executing the Z-axis canned operation.
For example, we have a six-inch square aluminum block, with a one-inch by one-inch deep flange on each side.
The print calls for two holes centered on each side of the flange. We need to write a program to avoid each of the
corners on the block.
