B-63324EN/03 PROGRAMMING 14.COMPENSATION FUNCTION
- 441 -
In the circular pocketing shown below, interference is detected
between the vector at the end point of block 1 and that of the end point
of block 2, and an attempt is made to calculate an intersection vector
between the post-compensation path for block 1 and the post-
compensation path for block 3 for interference avoidance. In this case,
there is no such post-compensation intersection because the paths
programmed in blocks 1 and 3 are circular. So, an alarm (PS0277) is
displayed and tool movement is stopped immediately before block 1, as
in the previous example.
