Traversing movements of the channel axes

Other channel axes, except the two geometry axes of the RESU working plane, are not
considered by RESU.
If traversing movements in other channel axes are required for machining continuation or
reverse travel, these can either be undertaken by the machined operator manually, or
programmed as travel block in the RESU-specific subroutine "CC_RESU_INI.SPF".
The machine operator must ensure that collision of the associated traversing movements
does not take place during the entire machining continuation operation within the framework
of the technological function of RESU.
15.9.2.3

Block numbers

The following RESU-specific subroutines and their subroutines must not contain block
numbers:
• CC_RESU_INI.SPF
• CC_RESU_END.SPF
The following alarm appears in the event of an error:
Alarm 75604 "Reverse travel not possible, error no.
15.9.2.4

Block search

Block search with calculation
RESU is subject to the following constraints in the context of the "block search with
calculation (on contour/at end of block") standard function:
• The last block of the RESU part program command CC_PREPRE(x) run during the block
search is effective in the target block.
• The retraceable contour range starts with the REPOS approach block.
Block search without calculation
RESU part program commands CC_PREPRE(x) haveno effect in the "block searches without
calculation" function.
15.9.2.5

Transformations

RESU can also be used for active kinematic transformation (e.g. 5-axis transformation)
subject to restrictions, as the traversing movements of the two geometry axes of the RESU
working plane are recorded in the basic coordinate system (BCS) and therefore before the
transformation.
