15. COMPENSATION FUNCTION
PROGRAMMING
335
When G29 is specified in cutter compensation C mode, an operation of
FS15 type is performed if CCN (bit 2 of parameter No. 5003) is set to 1.
This means that an intersection vector is generated in the previous block,
and vector cancellation is performed when a movement to an intermediate
position is performed. When movement from the intermediate position
to the return position is performed, the vector is restored; an intersection
vector is generated between the block and the next block.
(1)G29 specified in offset mode (with movement to both an intermediate
position and reference position performed)
(a) For specification made immediately after automatic reference
position return
When CCN (bit 2 of parameter No.5003)=0
