7.3 Probing Cycles

Skew Compensation

G68, axis rotation, cannot be used with skew compensation find.

Skew compensation is only supported for along the side edge of a part relative to the X,Y plane. Skew compensation is only supported for along the side edge of a part relative to the X,Y plane.

Calibrate the work probe at least once before trying to use this cycle.

A preliminary tool-length offset must be set by eye for the work probe. The tool offset, and work coordinate must be active before using this cycle in a program. See Section 4, "Tool-Length Offsets" on page 73.

The probe must be pre-positioned to the proper spot in relation to the part in accordance with the specified S parameter as described below or an I, J, and/or K should be included for pre-positioning.

The Skew compensation Finding Cycle can be run from within a program or from the Manual Data Input Mode .

Field	Code	Description
Action	Q	Q0 Finds the skew angle, but does not
		activate skew compensation.
		Q1 Finds the skew angle, and activates
		skew compensation.
		Q2 Activates skew compensation with the
		current skew value, but does not rerun the
		cycle on the part.
		If Q2 is used, all other skew compensation
		parameters are ignored.
		Before using skew compensation Q2, you
		must have called skew compensation at
		least once with Q0 or Q1, or the error
		message "Skew Compensation has not
		been found!" is displayed.
		Skew compensation is activated around the
		current active work coordinate and only
		works from within the program being run.
		Skew compensation cannot be activated
		directly or indirectly using skew
		compensation from the MDI mode.
		The operator can run the skew
		compensation from MDI but must place
		skew compensation Q2 inside the program
		for skew compensation to take effect.
		A G53 work coordinate call deactivates
		skew compensation, necessitating a
		re-issuance of skew compensation Q2 to
		activate skew compensation.
		Using Q1 or Q2 defaults the control to G90
		(Absolute). If you are in G91 (Incremental),
		you need to switch back after the cycle has
		been run. (Optional)
