Group of cycles
Cycles for pecking, reaming, boring,
counterboring, tapping and thread
milling
Cycles for milling pockets, studs and
slots
Cycles for producing point patterns,
such as circular or linear hole patterns
SL (Subcontour List) cycles which allow
the contour-parallel machining of
relatively complex contours consisting
of several overlapping subcontours,
cylinder surface interpolation
Cycles for face milling of flat or twisted
surfaces
Coordinate transformation cycles which
enable datum shift, rotation, mirror
image, enlarging and reducing for
various contours
Special cycles such as dwell time,
program call, oriented spindle stop and
tolerance
If you use indirect parameter assignments in fixed cycles
with numbers greater than 200 (e.g. Q210 = Q1), any
change in the assigned parameter (e.g. Q1) will have no
effect after the cycle definition. Define the cycle
parameter (e.g. Q210) directly in such cases.
If you define a feed-rate parameter for fixed cycles greater
than 200, then instead of entering a numerical value you
can use soft keys to assign the feed rate defined in the
TOOL CALL block (FAUTO soft key), or rapid traverse (FMAX
soft key).
If you want to delete a block that is part of a cycle, the TNC
asks you whether you want to delete the whole cycle.
