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 need not be named in the command. All other axes must be
specified in the commands.
