7.3 Probing Cycles

Field	Code	Description
DistInY	B	The distance from the starting point to
		move in the Y-axis to find the top of the part.
		The default is the current probe position.
		(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 Boss/Hole center.
		(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 the center
		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)
Repeat	R	If set to 1, the cycle does a preliminary
Meas		measure in the X-axis to get on center
		before measuring the Y-axis, making a total
		of 6 touches. If set to 0, the cycle only
		measures "X" once for a total of 4 touches.
		Default is: 0.
		(Optional)

To use the Inside/Outside Boss/Hole 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 the approximate center in X & Y within 0.1" (2.54 mm). 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 G144 Qn Xn Yn Wn. If this is run from inside a program, this line needs to be repeated for every boss/hole 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
