Circular Slot Cycle
Use the circular slot cycle to mill a slot along a circular path. You
must position the tool directly over the circle center prior to the
circular slot cycle block, or use the X and Y words.
Activate a tool prior to programming circular slot cycle so that the
CNC will know the cutter diameter.
Field Code Description
Diameter D Diameter of the slot circle. The diameter
must be larger than the slot width.
(Required)
StartAngle E The angle in degrees to the slot's first end.
(Required)
Sweep
Angle
F Sweep angle of the slot measured in
degrees between the two ends.
SweepAngle (F) is applied CCW from
StartAngle (E) regardless of the sign of its
value. Must be non-zero. (Required)
Width W Width of slot 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 slot. (Required)
StepOver A The distance the tool steps over (width of
cut) in the X and Y axes as it mills out the
slot. Defaults to tool radius, which is the
max.
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.
XCenter X X coordinate of the slot center point.
Defaults to current position.
