Cycles for pecking, reaming, boring,
counterboring, tapping and thread milling Page 292
Cycles for milling pockets, studs and
slots Page 342
Cycles for producing point patterns, such
as circular or linear hole patterns Page 376
SL (Subcontour List) cycles which allow
the contour-parallel machining of
relatively complex contours consisting of
several overlapping subcontours,
cylinder surface interpolation Page 383
Cycles for face milling of flat or twisted
surfaces Page 424
Coordinate transformation cycles which
enable datum shift, rotation, mirror
image, enlarging and reducing for various
contours Page 438
Special cycles such as dwell time,
program call, oriented spindle stop and
tolerance Page 456
If you use indirect parameter assignments in fixed cycles
with numbers greater than 200 (e.g. D00 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. D00 Q210) directly in such cases.
In order to be able to run cycles G83 to G86, G74 to G78
and G56 to G59 on older TNC models, you must program
an additional negative sign before the values for setup
clearance and plunging depth.
