HEIDENHAIN TNC 320 453
SLII Cycles 20 to 24:
„ Handling of coordinates and axis
values outside the working plane
„ Handling of islands which are not
contained in pockets
„ Set operations for SL cycles with
complex contour formulas
„ Radius compensation is active during
CYCL CALL
„ Paraxial positioning blocks in contour
subprogram
„ Miscellaneous functions M in contour
subprogram
„ Infeed movements in contour
subprogram
„ M110 (feed-rate reduction for inside
corner)
„ Error message is issued
„ Cannot be defined with complex
contour formula
„ Real set operation possible
„ Error message is issued
„ Error message is issued
„ Error message is issued
„ Error message is issued
„ Function does not work within SL
cycles
„ Axes that are outside the working
plane in the contour description are
ignored
„ Restricted definition in complex
contour formula is possible
„ Only restricted performance of real
set operation possible
„ Radius compensation is canceled,
program is executed
„ Program is executed
„ M functions are ignored
„ Infeed movements are ignored
„ Function also works within SL cycles
SLII Contour Train Cycle 25: APPR/DEP
blocks in contour definition Not allowed, machining of closed
contours is more coherent APPR /DEP blocks are allowed as contour
elements
General cylinder surface machining:
„ Contour definition
„ Offset definition on cylinder surface
„ Offset definition for basic rotation
„ Circle programming with C/CC
„ APPR /DEP blocks in contour definition
„ With X/Y coordinates, independent of
machine type
„ With datum shift in X/Y, independent
of machine type
„ Available function

„ Function not available
„ Machine-dependent, with existing
rotary axes
„ Machine-dependent datum shift in
rotary axes
„ Function not available

Cycle 28:
„ Complete roughing-out of slot
„ Definable tolerance

Cycle 29 Direct plunging to contour of ridge Circular approach to contour of ridge
Cycles 25x for pockets, studs and slots In limit ranges (geometrical conditions
of tool/contour) error messages are
triggered if plunging movements lead
to unreasonable/critical behavior In limit ranges (geometrical conditions
of tool/contour), vertical plunging is
used if required.
Touch probe cycles for datum setting
(manual and automatic cycles) Cycles can only be executed if the tilted
working plane function is inactive, the
datum shift is inactive and rotation with
Cycle 10 is inactive No restrictions in connection with
coordinate transformations
