Group of cycles Soft key
Cycles for pecking, reaming, boring, counterboring,
tapping and thread milling
Cycles for Milling Pockets, Studs and Slots
Cycles for producing hole patterns, such as circular or
linear 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. 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.
