7 Programming: Canned Cycles, sub-programs



Use the ring pocket cycle to mill a circular frame or trough around a 
circular 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.

IslandDia

D

Diameter of island in X/Y axes. (Required)

StartHgt

Z absolute starting height (0.1” or 2 mm 
above surface). Executed in rapid.

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.

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.
