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
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
● You have not specified a value for
● 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.
