SUBPROGRAMS AND C ANNED C YCLES
After reviewing the canned cycle, we can get a good idea of the amount of lines of code required to produce the
five holes. The best way to conserve on program space and programming time is to use a subprogram. We can
do this by grouping the X and Y locations of the holes into a separate program and then calling up this program
when we need to tell a canned cycle the X,Y coordinates.
Instead of writing the X,Y locations once for each tool, we can write the X,Y locations once for any number of
tools.
The canned cycle program that we reviewed on the previous page could use some constructive rearranging.
