Acu-Rite CNC 3500i User Manual

7 Programming: Canned Cycles, sub-programs



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. 

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.
