7 Programming: Canned Cycles, sub-programs



Use the plunge rectangular pocket cycle for carbide tooling, where 
a multiple-axis ramp-in move is not possible. The Z-axis plunges 
(single axis) to the programmed depth. You must position the tool 
directly over the center of the pocket prior to the plunge rectangular 
pocket cycle block, or use the X Y words.



Activate the tool prior to programming plunge rectangular pocket 
cycle, so the cutter diameter is known.

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.

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.

CornerRad

U

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

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.
