7 Programming: Canned Cycles, sub-programs

To use the skew compensation Cycle:



Place the probe in the spindle with its tool number active and the 
tool type set to "Touch Probe".



Manually jog the probe stylus to the appropriate start position 
relative to the part as specified by the S parameter in Table 5-56, 
skew compensation above. X or Y should be within 0.1" (2.54 mm) 
of the part edge. If H = 1, the Z-axis should be within 0.1" (2.54 mm) 
above the part otherwise the Z-axis should be at the side picking 
depth. If run from within a program, probe must be pre-positioned.



Skew compensation Qn Sn. If this is run from inside a program, this 
line needs to be repeated every time you wish to find a skew angle.



Execute the line in Manual Data Input Mode by touching Start.

DistInX

A

The distance from the starting point to 
move in the "X" axis to find the top of the 
part. The Default is: 1.0" (25.4 mm) toward 
the part at the angle specified in the S cycle 
parameter. (Optional)

DistInY

B

The distance from the starting point to 
move in the "Y" axis to find the top of the 
part. The Default is: 1.0" (25.4 mm) toward 
the part at the angle specified in the S cycle 
parameter.  (Optional)

X

I

This causes the cycle to make a protected 
X move to the coordinate entered relative 
to the current active work coordinate 
before finding the skew angle. 
(Optional)

Y

J

Same as I only for the Y-axis. 
(Optional)

Z

K

Same as I only for the Z-axis. 
(Optional)

When positioning the probe from within the program you 
should always use the G146 (Protected Probe Positioning) 
cycle (see G146 instructions above in this document) or 
use the I, J, or K parameters for the same purpose.
