Acu-Rite CNC 3500i user manual Circular Slot Cycle

Circular Slot Cycle

Use the circular slot cycle to mill a slot along a circular path. You must position the tool directly over the circle center prior to the circular slot cycle block, or use the X and Y words.

Activate a tool prior to programming circular slot cycle so that the CNC will know the cutter diameter.

Field	Code	Description
Diameter	D	Diameter of the slot circle. The diameter
		must be larger than the slot width.
		(Required)
StartAngle	E	The angle in degrees to the slot's first end.
		(Required)
Sweep	F	Sweep angle of the slot measured in
Angle		degrees between the two ends.
		SweepAngle (F) is applied CCW from
		StartAngle (E) regardless of the sign of its
		value. Must be non-zero. (Required)
Width	W	Width of slot in Y-axis. (Required)
StartHgt	H	Z absolute starting height (0.1” or 2 mm
		above surface).
		Executed in rapid. (Required)
ZDepth	Z	Absolute depth of slot. (Required)
StepOver	A	The distance the tool steps over (width of
		cut) in the X and Y axes as it mills out the
		slot. Defaults to tool radius, which is the
		max.
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.
XCenter	X	X coordinate of the slot center point.
		Defaults to current position.
