10.9 Repositioning to the contour (REPOSA, REPOSL, REPOSQ, REPOSQA, REPOSH, REPOSHA, DISR, DISPR, RMIB
Approaching with a new tool
The following applies if you have stopped the program run due to tool breakage:
When the new D number is programmed, the machining program is continued with modified
tool offset values at the repositioning point.
Where tool offset values have been modified, it may not be possible to reapproach the
interruption point. In such cases, the point closest to the interruption point on the new
contour is approached (possibly modified by DISPR).
Approach contour
The motion with which the tool is repositioned on the contour can be programmed. Enter
zero for the addresses of the axes to be traversed.
The REPOSA, REPOSQA and REPOSHA commands automatically reposition all axes.
Individual axis names need not be specified.
When the commands REPOSL, REPOSQ and REPOSH are programmed, all geometry
axes are traversed automatically, i.e. they do not have to be specified in the command. All
other axes must be specified in the commands.
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.
