Plunge Rectangular Pocket Cycle
 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.
Field Code Description
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.
