Acu-Rite CNC 3500i user manual 163

Field	Code	Description
TPIor Lead	B	Threads per inch (TPI) or lead of thread in
		MM. (Required)
		NOTE: The minimum number of threads
		per inch is "1".
XCenter	X	Absolute X coordinate of the center of the
		thread. If no coordinate is entered, the CNC
		puts the center of thread at the current tool
		position.
YCenter	Y	Absolute Y coordinate of the center of the
		thread. If no coordinate is entered, the CNC
		puts the center of thread at the current tool
		position.
ArcInRad	R	Size of radius arcing into start of thread.
		NOTE: If R is a positive value or not set and
		the thread is "inside", the cycle always
		returns to the center between passes.
		If R is a negative value, the cutter moves to
		the start or end point that is closest to the
		center if inside thread, and farthest away
		from center if outside thread.
		If R is not specified at all and the thread is
		outside, the cutter backs away from the
		largest diameter by an amount equal to the
		thread depth.
StockAmt	S	Amount to leave for a finish pass after the
		roughing passes.
Rough	J	Feedrate for roughing. If not set (blank), the
Feed		cycle uses the current active feedrate.
FinFeed	K	Feedrate for the finish pass. If not set
		(blank), the cycle uses the current active
		feedrate.
Passes	E	Number of roughing cuts to be taken.
		NOTE: If Stock is not set or set to zero and
		E is 1 or 0, the cycle makes just one pass at
		the full depth.
		If Stock is set to greater than zero and E is
		1 or 0, the cycle makes one pass at the
		stock depth and one pass at full thread
		depth.
		NOTE: If you would like all non-cutting
		positioning moves to be rapid, set E to a
		negative number.
