Acu-Rite CNC 3500i user manual 251

Blocks 1 through 5 are comments.

Blocks 6 through 8 define common defaults.

Block 9 defines the blockform or stock size. This is only needed for the 3D solid.

Block 10 defines the initial roughing tool which has a 1” diameter.

The parameters for this tool must either come from the tool table or be saved in the tool table. This is a requirement for the coarse tool feature.

Blocks 11 through 13 define RPM and turn on the spindle and coolant.

Block 15 defines the islands in sub-programs #2, #3 and #4. The actual islands are then defined in blocks 41-47, 50-54 and 57-61

The island must always be programmed before the corresponding pocket. Also note that the island must specify the machining side. In this case, since the island profile is defined in a clockwise orientation, the machining side is to the left. Except for sub-program #4 is nested inside of sub-program #3; thus, this needs to have the machining side set to Right (see block 58).

Block 16 is a now an irregular pocket defined by sub-program #1. Note that finish stock is specified and the cycle is requested to skip the finish pass. This is required for the stand alone finish cycles.

Block 17 defines the finer roughing tool which a 1/4” diameter.

Block 18 re-defines the island for the finer roughing tool.

Block 19 re-defines the pocket for the finer roughing tool with the specification of the coarsetool=1.

Specifying the coarse tool as tool #1 allows the pocket cycle to calculate the material left by the coarse tool and only machine the required material. Also note that finish stock is specified and the cycle is requested to skip the finish pass. This is required for the stand alone finish cycles.
