Rounding behavior with synchronized paths
Angular path
Angular path
Path criterion
The size of the rounding area can be controlled by path criteria ADIS and ADISPOS. These
are the precoincidences for the block change. ADIS and ADISPOS describe the distance,
which the rounding block may begin, at the earliest, before the end of the block or the
distance after the end of block within which the rounding block must be terminated.

Acute angles produce rounding curves with a large degree of curvature and therefore cause
a corresponding reduction in velocity.
Parameterization of the path criterion
• ADISPOS is programmed in the same way as ADIS, but must be used specifically for
• ADIS and ADISPOS are preset in the part program.

movements in rapid traverse mode (G00).
For example, ADIS = 0.3 indicates a path criterion with a rounding distance of 0.3 mm
(ADISPOS is the same).
