7.3 Probing Cycles

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)

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

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

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.

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.

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