7.3 Probing Cycles
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.
Field Code Description
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.
