TNC 620
Cannot be defined with
complex contour formula
Real set operation possible
Error message is issued
Error message is issued
Error message is issued
Function does not work within
SL cycles
Not allowed, machining of closed
contours is more coherent
With X/Y coordinates,
independent of machine type
With datum shift in X/Y,
independent of machine type

Function available
with Direct plunging to contour of
ridge
In limit ranges (geometrical
conditions of tool/contour)
error messages are triggered
if plunging movements lead to
unreasonable/critical behavior
iTNC 530
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
Function also works within SL
cycles
APPR/DEP blocks are allowed as
contour elements
Machine-dependent, with
existing rotary axes
Machine-dependent datum
shift in rotary axes

Function available
Circular approach to contour of
ridge
In limit ranges (geometrical
conditions of tool/contour),
vertical plunging is used if
required
