Corner rounding with ADIS and ADISPOS
Note
Rounding cannot be used as a substitute for smoothing (RND). The user should not make
any assumptions with respect to the appearance of the contour within the rounding area. The
type of rounding can depend on dynamic conditions, e.g., on the tool path velocity. Rounding
on the contour is therefore only practical with small ADISvalues. RND must be used if a
defined contour is to be followed at the corner without exception.
ADISPOS is used between G0 blocks. This enables the axis movement to be smoothed
substantially and the traversing time to be reduced during positioning.
If ADIS/ADISPOS is not programmed, a value of zero applies and the traversing behavior
therefore corresponds to G64. The rounding clearance is automatically reduced (by up to
36%) for short traversing distances.

Continuous-path mode
Continuous-path mode with programmable transition rounding
Corner rounding with axial tolerance, with modal activated
Block-internal corner rounding

STRING-type character string
Executable block is generated explicitly for MSG. If the MSG procedure is
programmed without the 2nd parameter, the message "Text" is output with
the next executable block.
