Acu-Rite CNC 3500i user manual Slot Cycle

7.2 Canned Cycles

Slot Cycle

Use the Slot Cycle to mill a slot.

A slot is defined by a center (X,Y), length, width, and depth.

If X and Y variable words are not programmed, the CNC will use the current position as the slot center. The tool needs to be positioned at the center of the slot.

The XY plane must be selected prior to the slot cycle block; otherwise, an error is displayed.

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

Field	Code	Description
Length	M	Length of pocket in X-axis. (Required)
Width	W	Width of pocket 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 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.
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.
Angle	C	The angle in degrees by which the slot is
		rotated. The center of rotation lies in the
		center of the slot. Default is 0 degrees.
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.
