Calling cycles
The following cycles become effective automatically as soon as they
are defined in the part program. These cycles cannot and must not be
called:
„ Cycle 220 for point patterns on circles and Cycle 221 for point
patterns on lines
„ SL Cycle 14 CONTOUR GEOMETRY
„ SL Cycle 20 CONTOUR DATA
„ Cycle 32 TOLERANCE
„ Coordinate transformation cycles
„ Cycle 9 DWELL TIME
„ All touch probe cycles
You can call all other cycles with the functions described as follows.
Prerequisites
The following data must always be programmed before a
cycle call:
„ BLK FORM for graphic display (needed only for test
graphics)
„ Tool call
„ Direction of spindle rotation (M functions M3/M4)
„ Cycle definition (CYCL DEF)
For some cycles, additional prerequisites must be
observed. They are detailed in the descriptions for each
cycle.
