In the above example, the arc in block N6 is placed in the one quadrant. But, after cutter
compensation, the arc is extended to the four quadrants.
2) Correction of interference in advance
(a) The vector movement corresponding to the interference
When cutter compensation is performed for blocks A, B and C and vectors

between B and C are produced, firstly check
the nearest vectors. If interference occurs, they are ignored. But if the vectors to be ignored due to
interference are the last vectors at the corner, they cannot be ignored.
Interference check before N4 and N5 → Interference → V
4
and V
5
are ignored.
Check V

and V
6
→ Interference → Ignored
Check V
2
and V
7
→ Interference → Ignored
Check V
1
and V
8
→ Interference → can not be ignored
The check is stopped if the vector interference does not found during the detection.
If block B is a circular arc, a linear movement is produced if the interference occurs.
Example: The tool moves linearly from V
1
to V

Example 2: Tool linear movement is shown below:
