Variable Programming Examples
This program uses common variables in the range of #50 to #149. The
program mills a pocket with a three-degree draft angle on the
sidewalls. The dimensions at the bottom of the pocket are:
15.5730 (X axis) x 13.8850 (Y axis). The pocket is 1.0000 in. deep.
The tool begins at the upper-left corner of the pocket and at full depth.
Part Zero is set in the center of the pocket.
