8 Programming: Cycles 120
8.1 General Overview of Cycles
Frequently recurring machining cycles that comprise several
working steps are stored in the TNC memory as standard cycles.
Coordinate transformations and other special cycles are also
provided as standard cycles. The table at right shows the various
cycle groups.
Fixed cycles with number starting with 200 use Q parameters as
transfer parametersParameters with specific functions that are
required in several cycles always have the same number: For
example, Q200 is always assigned the setup clearance, Q202 the
plunging depth, etc.
Defining a cycle
ú The soft-key row shows the available groups of cycles
ú Press the soft key for the desired group of cycles, for
example DRILLING for the drilling cycles
ú Select the desired cycle, for example PECKING. The
TNC initiates the programming dialog and asks all
required input values. At the same time a graphic of
the input parameters is displayed in the right screen
window. The parameter that is asked for in the dialog
prompt is highlighted. Select the screen layout
PROGRAM + HELP GRAPHIC.
ú Enter all parameters asked by the TNC and conclude
each entry with the ENT key
ú The TNC terminates the dialog when all required data
have been entered
Resulting NC blocks
CYCL DEF 1.0 PECKING

Group of cycles Soft Key
Cycles for pecking, reaming, boring
and tapping
Cycles for milling pockets, studs
and slots
Cycles for producing regular point
patterns, such as circular hole patterns,
hole surfaces or irregular point patterns
via point tables
Subcontour List (SL) cycles, which
allow the machining of more complex
contours comprising several
overlapping subcontours.
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 and oriented spindle stop
