Rectangular Pocket Cycle
Use the rectangular pocket cycle to mill square or rectangular
pockets. You must position the tool directly over the center of the
pocket prior to the Rectangular Pocket cycle, or use the X Y data.
Activate a tool prior to programming, so cutter diameter is known.
Field Code Description
Length M Length of pocket in X-axis. (Required)
Width W Width of pocket in Y-axis. (Required)

above surface). Executed in rapid.

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.

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

negative value will cause the finish pass to
finish the side walls in steps down.
