Function TNC 620 iTNC 530
SLII Cycles 20 to 24:
Behavior with islands 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
Paraxial positioning blocks in
contour subprogram
Error message is issued Program is executed
Miscellaneous functions M in
contour subprogram
Error message is issued M functions are ignored
Cylinder surface machining in
general:
Contour definition With X/Y coordinates,
independent of machine type
Machine-dependent, with
existing rotary axes
Offset definition on cylinder
surface
With datum shift in X/Y,
regardless of machine type
Machine-specific datum shift in
rotary axes
Offset definition for basic
rotation
Function available Function not available
Circle programming with C/CC Function available Function not available
APPR/DEP blocks in contour
definition

Cylinder surface machining with
Cycle 28:
Complete roughing-out of slot Function available Function not available
Definable tolerance Function available Function available
Cylinder surface machining with
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 plung-
ing movements lead to unreason-
able/critical behavior
In limit ranges (geometrical condi-
tions of tool/contour), vertical
plunging is used if required
