Block search

Block search with calculation
RESU is subject to the following supplementary conditions in the context of the block search
with calculation (on contour/at end of block) standard function:
• The last CC_PREPRE(x) RESU part program command run during the block search is
• The retraceable contour range starts with the REPOS approach block.
Block search without calculation
CC_PREPRE(x) RESU part program commands have no effect during block searches
without calculation.
3.2.5

Transformations

Meaning
RESU can also be used for active kinematic transformation (e.g. 5-axis transformation)
subject to restrictions, as the traversing movements of the first two geometry axes on the
channel are recorded in the basic coordinate system (BCS) and therefore before the
transformation.
Transformation changeover
While RESU is active, no transformation changes are permitted to take place and
transformation must not be activated/deactivated.
RESU is active:
• Start: Part program command CC_PREPRE(1)
• End: Program end or part program command CC_PREPRE(-1)
You will find a complete description of the transformations in:
