Acu-Rite CNC 3500i User Manual

7 Programming: Canned Cycles, sub-programs



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. 

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.
