Repositioning to the contour along a semicircle, REPOSH, REPOSHA
The tool approaches the repositioning point along a semi-circle with a diameter of DISR=.... The
control automatically calculates the necessary intermediate point between the start and
repositioning point.
Example
REPOSH RMIBL DISR=20 F400
Specifying the repositioning point (not for SERUPRO approaching with RMNBL)
With reference to the NC block in which the program run has been interrupted, it is possible to
select one of three different repositioning points:
● RMIBL, interruption point
● RMBBL, block start point or last end point
● RMEBL, block end point
