Cycles for pecking, reaming, boring,
counterboring, tapping and thread
milling Page 358
Cycles for milling pockets, studs and
slots Page 410
Cycles for producing point patterns,
such as circular or linear hole patterns Page 440
SL (Subcontour List) cycles which allow
the contour-parallel machining of
relatively complex contours consisting
of several overlapping subcontours,
cylinder surface interpolation Page 447
Cycles for face milling of flat or twisted
surfaces Page 498
Coordinate transformation cycles which
enable datum shift, rotation, mirror
image, enlarging and reducing for
various contours Page 513
Special cycles such as dwell time,
program call, oriented spindle stop and
tolerance Page 533
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 (F AUTO soft key). You can also use the
feed-rate alternatives FMAX (rapid traverse), FZ (feed per
tooth) and FU (feed per rev), depending on the respective
cycle and the function of the feed-rate parameter.
Note that, after a cycle definition, a change of the FAUTO
feed rate has no effect, because internally the TNC
assigns the feed rate from the TOOL CALL block when
processing the cycle definition.
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.
