Acu-Rite CNC 3500i user manual Tool Probe Calibration Cycle, 199

Tool Probe Calibration Cycle

This is used to set the Z datum for length preset, the effective probe stylus diameter for setting tool diameter registers, and establishes the center of the probe stylus.

Calibration must be done at least once before using the tool probe. Once the probe has been calibrated, calibration does not need to be done again unless the probe is moved or a new part is being setup. The cycle must always know the relationship between the top of the part and the top of the probe to set the TLO.

This cycle is used to calibrate the probe. This is used to set the Z datum for length preset, establishing the center of the probe stylus, and the effective probe stylus diameter for setting tool diameter registers.

Field	Code	Description
DiamOfStd	D	The diameter of the part of the calibration
		standard that comes in contact with the
		probe stylus during calibration. This should
		be an exact measurement. (Optional)
		override for the
		DiameterOfToolProbeGauge machine
		setup parameter) .
DistDown	E	The incremental distance from the current Z
		Retract amount to go down along the side
		of the probe stylus when doing a diameter
		pick. The maximum E value is 0.55" (13.97
		mm) or the tool may crash into the probe or
		table. If you enter a value larger than 0.55"
		(13.97 mm), the control issues an error
		message. If E is not set, the cycle uses a
		default value of 0.1" (2.54 mm). (Optional)
		[Default: 0.1"]. Z Retract Amount is set in
		the Tool Probe Parameters.
