Circular Pocket Cycle

Use the circular pocket cycle to mill round pockets. You must position the tool directly over the center of the pocket prior to the block, or use the X Y data.

Activate the tool prior to programming the pocket cycle, so the cutter diameter is known.

Field	Code	Description
Diameter	D	Diameter of pocket in X and Y axes.
		(Required)
StartHgt	H	Z absolute starting height (0.1" or 2 mm
		above surface). Executed in rapid.
		(Required)
ZDepth	Z	Absolute depth of pocket. (Required)
StepOver	A	The distance the tool steps over (width of
		cut) in the X and Y axes as it mills out the
		pocket. Defaults to tool radius, which is the
		max.
XCenter	X	X coordinate of the pocket center point.
		Defaults to current position.
YCenter	Y	Y coordinate of the pocket center point.
		Defaults to current position.
DepthCut	B	The depth of each cut per pass. Defaults to
		tool diameter. Max is the full ZDepth in
		parameter Z, less bottom finish stock. A
		negative value will cause the finish pass to
		finish the side walls in steps down.
FinStock	S	Amount of stock left by the roughing
		passes for a finish pass. This amount
		applies to the sides and bottom unless R
		(SideStock) is defined; then, S (FinStock)
		only applies to the bottom. Default is no
		stock left.
