Function TNC 620 iTNC 530
SLII Cycles 20 to 24:
Handling of islands which are
not contained in pockets
Cannot be defined with
complex contour formula
Restricted definition in complex
contour formula is possible
Set operations for SL cycles
with complex contour formulas
Real set operation possible Only restricted performance of
real set operation possible
Radius compensation is active
during
CYCL CALL
Error message is issued Radius compensation is
canceled, program is executed

contour subprogram
Error message is issued Program is executed
Miscellaneous functions M in
contour subprogram
Error message is issued M functions are ignored
M110 (feed-rate reduction for
inside corner)
Function does not work within
SL cycles
Function also works within SL
cycles

Cycle 29
Direct plunging to contour of ridge Circular approach to contour of
ridge
Cycles 25x for pockets, studs
and slots:
Plunging movements 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
