ACU-RITE 3500i

This section describes operation and an overview of the tool and 
spindle probe canned cycles available on the 3500i CNC products. The 
cycles provided perform the most common tool and spindle probing 
functions. Custom cycles to perform specific functions can be written 
using the primitive and parametric programming. If Probing has been 
added post-sale, beside Machine Parameter changes, there may be 
Programmable Logic Controller (PLC) program modifications required. 

The tool probe cycles are only supported on machines with automatic 
spindle forward/reverse and spindle speed, and homing with a 
permanent X, Y, and Z machine position. The method described 
assumes the use of negative tool-length offsets. In this method, the 
Tool-Length Offset (TLO) in the length column for each tool represents 
the distance from the tool tip at machine home to top of work piece 
and is a negative number. This method does not require the use of any 
Z work coordinate offset to be active. This procedure finds the 
effective tool diameter by turning the spindle on in reverse and 
touching two sides of the probe stylus, then storing the tool's 
diameter in the tool's diameter offset table.

The spindle probing cycles are designed to assist in part setup. Using 
these cycles, one or more features (edges) of a part can be measured. 
Using the data obtained with these measurements, calculations are 
made that can be used to set a given fixture offset. It is also possible 
to find the orientation angle of a part so as to not always have to align 
the part exactly. 

Tool and spindle probing does not allow rotation, scaling, and 
mirroring. Plane is set to XY when these cycles are complete.

The use of all Tool Probe and Spindle Probe cycles 
requires the purchase of the Touch Probing Cycles 
Software Option, I.D. 648809-01. These cycles will not 
execute, and will generate program stop errors if 
attempted to be used without this option enabled on the 
system SIK.
