Path traversing behavior
8.6 Repositioning to a contour (REPOSA, REPOSL, REPOSQ, REPOSQA, REPOSH, REPOSHA, DISR,
DISPR, RMI, RMB, RME, RMN)
The following applies to the REPOSH and REPOSQ circular motions:
The circle is traversed in the specified working planes G17 to G19.
If you specify the third geometry axis (infeed direction) in the approach block, the
repositioning point is approached along a helix in case the tool position and programmed
position in the infeed direction do not coincide.
In the following cases, the control automatically
switches over to linear approach REPOSL:
● You have not specified a value for DISR.
● No defined approach direction is available (program interruption in a block without travel
● With an approach direction that is perpendicular to the current working plane.
