Fanuc alarm PS0041: INTERFERENCE IN G41/G42
PS alarm (program/operation) · Fanuc 0i-D
What it means
During cutter or tool-nose radius compensation, the control detected that executing the compensated path would remove excessive material — the compensated blocks interfere. The contour must be reprogrammed or a smaller tool used.
Likely causes
- Cutter/nose radius larger than internal corner geometry
- Very short consecutive moves with large compensation
- Wrong G41/G42 side selection creating gouge conditions
