7.3 Probing Cycles

Manual Tool-Length Offset Preset

Updates tool-length register. To be used for large face mill style tools or shell mill tools that have a hole in the center of the bottom of the tool.

This cycle is used to measure the length of large face mill style tools that have a hole in the center of the bottom of the tool.

Field	Code	Description
Tool#	T	Tool number. (Required)
		With only the T parameter present, the
		spindle turns on in reverse and the canned
		cycle comes straight down measuring the
		tool length and storing it in the tool-length
		register. The T parameter must the same as
		the current tool in the spindle.
EstDiam	D	This is the rough diameter of the tool and is
		only used in this cycle to determine if the
		spindle should be turned on in reverse or
		forward. If you have a left-handed tool you
		would give a negative value to the
		diameter. If this parameter is left off, the
		control always turns on in reverse by
		default. (Optional)
OvrMed	M	This is the override for the medium
Feed		feedrate that was set in the machine setup
		parameter ZFirstPickFeedRate_Medium.
		Sometimes there may be a tool that has a
		large diameter making it necessary to slow
		it down to prevent the touch probe from
		being hit too hard. This can only be set
		slower. Trying to set this higher will result
		in the software using the original feedrate.
		(Optional)
