Modifying Canned Cycles
In this section we will cover canned cycles that have to be customized in order
to make the programming of difcult parts easier.
Using G98 and G99 to clear clamps – For example, A square part being held
to the table with one-inch tall table clamps. A program needs to be written to
clear the table clamps.

X, Y Plane Obstacle Avoidance In A Canned Cycle:
To avoid an obstacle in the X, Y plane during a canned cycle place an L0 in a
canned cycle line to make an X, Y move without executing the Z-axis canned
operation.
For example, having a six-inch square aluminum block, with a one-inch by one-
inch deep ange on each side, the print calls for two holes centered on each
side of the ange. The program to avoid each of the corners on the block.
