7.2 Canned Cycles

Field	Code	Description
CornerRad	U	Corner radius setting. If the programmer
		enters a negative value, both direction of
		cut and the starting and endpoints reverse.
ZFeed	I	Z-axis feedrate.
Rough	J	Rough-pass feedrate.
Feed
FinFeed	K	Finish-pass feedrate.
DepthCut	B	Maximum Z-axis increment used for each
		pass.
FinStock	S	Amount of stock left by the machine before
		the finish pass. Default: 0. If the
		programmer enters a negative value, the
		CNC leaves the stock without making a
		finish pass.
RetractHgt	P	Retract height.

When you enter a value, the CNC executes the number of passes required to get from the H (StartHgt) to the Z (ZDepth), cutting the B (DepthCut) on each pass.

When you enter an S (FinStock) value, the CNC leaves the specified stock on the profile and depth for a finish pass. The CNC cuts the rectangle to the M (Length), W (Width), and Z (ZDepth) dimensions on the finish pass. Enter a negative S (FinStock) to leave the finish stock without making a finish pass.

When you do not enter a J (RoughFeed) or K (FinFeed), the CNC executes feed moves at the current feedrate. J (RoughFeed) controls the feedrate of the roughing cycle. K (FinFeed) controls the feedrate of the finishing cycle.
