AFSL and WID (angle and circumferential slot width)
Use the parameters AFSL and WID to define the form of a slot in the plane. The cycle checks whether the slot width is
violated with the active tool. Otherwise, alarm 61105 "Cutter radius too large" will be activated and the cycle aborted.
CPA, CPO and RAD (center point and radius)
You define the position of the circle in the machining plane by the center point (CPA, CPO) and the radius (RAD). Only
positive values are permitted for the radius.
FFCP
Use the parameter FFCP to program a special feedrate for intermediate positioning on circular path.
STA1 and INDA (starting and incremental angle)
The arrangement of the circumferential slots on the circle is defined by these parameters.
STA1 defines the angle between the positive direction of the first axis (abscissa) of the workpiece coordinate system active
before the cycle was called and the first slot.
The INDA parameter contains the angle from one circumferential slot to the next.
If INDA=0, the incremental angle is calculated from the number of circumferential slots so that they are arranged equally
around the circle.
Note
A tool compensation must be programmed before the cycle is called. Otherwise, the cycle is aborted and alarm 61000 "No
tool compensation active" is output.
If incorrect values are assigned to the parameters that determine the arrangement and size of the slots and thus cause
mutual contour violation of the slots, the cycle is not started.
The cycle is aborted and the error message 61104 "Contour violation of slots/elongated holes" is output.
During the cycle, the workpiece coordinate system is offset and rotated. The actual value display in the workpiece coordinate
system is always shown such that the circumferential slot currently being machined starts on the first axis of the current
processing level and the zero point of the workpiece coordinate system is in the center of the circle.
After the cycle has been completed, the workpiece coordinate system is in the same position again as it was before the
cycle was called.
Programming example1: Slots2
Use this program to machine three circumferential slots arranged at a circle with center point X60 Y60 and radius 42 mm in
the XY plane. The circumferential slots have the following dimensions: Width 15 mm, angle for slot length 70 degrees, depth
23 mm. The initial angle is 0 degree, the incremental angle is 120 degrees. The slot contours are machined to a final
machining allowance of 0.5 mm, the safety clearance in infeed axis Z is 2 mm, the maximum depth infeed is 6 mm. The slots
are to be completely machined. Speed and feedrate are to be the same when finishing. The infeed when finishing is to be
performed to slot depth.
