Acu-Rite CNC 3500i User Manual

ACU-RITE 3500i



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. 



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



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.

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.

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).

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.
