SECTION 12 USER TASK
[Program Sequence]
(1) Assume that there are a number of pulleys with a similar contour, shown as above. To simplify
the programs of these pulleys, express the contour of part A using variables.
(2) Program the pulley groove cutting cycle as a subprogram using the variables.
Since this program is called for after execution of axis motion command(s), it is prepared in
incremental mode so that it can be used wherever it is called.
The subprogram file name is "PULL-PTTN1.SUB".
