Acu-Rite CNC 3500i User Manual

7 Programming: Canned Cycles, sub-programs



Use the frame pocket cycle to mill a frame or trough around an 
island of material. You must position the tool directly over the center 
of the island, or use the X Y words. 



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

Length

M

Length of island in X-axis. (Required)

Width

W

Width of island 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 frame pocket. (Required)

Frame 
Width 

C

Width of removed trough or frame. 
(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 island center point. 
Defaults to current position.

YCenter

Y

Y coordinate of the island center point. 
Defaults to current position.

InsideRad

U

The arc radius of all four inner corners of the 
island. Defaults to tool radius, which is the 
minimum value allowed.

Outside 
Rad

V

The arc radius of all four outer corners of 
the frame pocket. Defaults to U (InsideRad) 
value. Must exceed tool radius.

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.
