Fanuc alarm PS0038: INTERFERENCE IN CIRCULAR BLOCK
PS alarm (program/operation) · Fanuc 0i-D
What it means
In radius-compensated machining, overcutting would occur because the arc start point or end point coincides with the arc center. The compensated toolpath cannot be generated for that block.
Likely causes
- I/J/K computed so the start/end point equals the center
- Full-circle programmed with wrong vector words under comp
- Cutter radius larger than the arc geometry allows
