11.4 Advanced Programming
The pocket is milled with a side draft angle of three degrees. Z is set
to a step-up increment of .02 in. #152 can be set to a desired value,
perhaps to determine the finish on the sidewalls of the pocket. In this
example, the pocket always has a depth of 1 in., and a draft angle of 3
degrees. The side lengths and Z step may be changed.
To make this program totally independent, the Z depth and draft angle
can be set to variables, and the additional calculations must then be
made.
This program requires the length and width of a rectangle, the cut per
side on the rectangle, and the number of passes around the rectangle.
Variables #150 to #199 are read only. They can be set only in the main
program.
