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 toward the corner being
		found 0.4" (10.16 mm). (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 toward the corner being
		found 0.4" (10.16 mm). (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 corner.
		(Optional)
Y	J	Same as I only for the Y-axis. (Optional)
Z	K	Same as I only for the Z-axis. (Optional)
Offset	W	Work Coordinate to update with edge
		location in X- and Y-axes. If set, work
		coordinate is updated. Work coordinate
		register is not updated if not set and a
		warning message tells the operator no
		update has taken place if W is not set.
		(Optional)

To use the Inside Corner Finding 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 0.1" (2.54 mm) away from the inside of the corner you wish to find in X & Y. 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.

Type G143 Qn Wn. If this is run from inside a program, this line needs to be repeated for every corner you wish to find or whose position you want to reestablish.

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

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