Acu-Rite CNC 3500i User Manual

ACU-RITE 3500i

Facing cycles simplify the programming required to face the surface 
of a part. 



Execution begins one tool radius from the D and E (start point). The 
selected stepover determines the approach axes.



Facing cycles can start in any corner of the surface and cut in any 
direction, depending on the sign (+/-) of the X (Length) and A (Width) 
values. Program a slightly oversized X and A to ensure complete 
facing of the surface.

At the end of the cycle, the tool rapids to H, then rapids back to D and 
E (start position).

Length

X

The feedrate at which the tool will "ramp" 
into the pocket in all three axes. Default is 
last programmed feedrate.

Width

Y

Feedrate used during finish passes. Default 
is last programmed feedrate.

StartHgt

H

The Absolute Z position before beginning 
the facing cycle. This must be 0.1” (or 2 
mm) above the surface. Executed in rapid. 
(Required)

ZDepth

Z

Absolute depth of the finished surface. 
(Required)
NOTE: ZDepth must be lower than 
StartHgt. StartHgt is 0.1” (2.0 mm) above 
the work surface.

XStepOver

A

Width of cut in the X-axis direction. When 
you do not enter a value, the CNC defaults 
to 70% of the active tool radius. Maximum 
step-over permitted is 70% of the active 
tool radius.

YStepOver

B

Width of cut in the Y-axis direction. When 
you do not enter a value, the CNC defaults 
to 70% of the active tool radius. Maximum 
stepover permitted is 70% of the active tool 
radius.

Feed

F

Feedrate used in cycle.
