Working with Cycles
Certain frequently needed machining sequences are stored in the TNC as
cycles. Coordinate transformations and other special cycles are also
provided as standard cycles.

8 Select the cycle.
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
„ In order to avoid erroneous entries during cycle definition,
you should run a graphical program test before machining.
„
The algebraic sign for the cycle parameter DEPTH
determines the machining direction.
„ For all cycles with numbers above 200 the TNC
automatically pre-positions the tool in the tool axis.
