7.4 Sub-programs

Blocks 1 through 4 are comments.

Blocks 5 through 7 define common defaults.

Block 8 defines the blockform or stock size. This is only needed for the 3D solid. The stock defined is 6x6 with center at 0,0.

Blocks 9 through 12 define the tool, RPM and turn on the spindle and coolant.

Block 14 defines an island in sub-program #1. The actual island is then defined in blocks 19 through 27.

The island must always be programmed before the corresponding pocket. Also note that the island must specify the machining. In this case, since the island profile is defined in a clockwise orientation, the machining side is to the left (see block 22).

Block 15 is a circular pocket with 4” with center at 0, 0.

This is the rendering of the program after being ran in Draw. The top view is the line draw, and the bottom view is the 3D solid model.

Approximate machining time is 8-1/2 minutes.
