3505
Invalid Machining Start Point
Fanuc · Series 0i Manual Guide
¿Qué significa 3505 ?
This MC alarm (specific to Series 30i) indicates that the machining start point defined in the program is invalid. This could be due to a coordinate outside the work envelope, an unreachable point, or a point that interferes with existing geometry, preventing the machining cycle from initiating correctly.
Causas comunes
- The computed start point for the cutting path is not achievable.
- Previous operation left the tool in an inaccessible position.
- Axis home position has been lost or incorrectly set.
- Program error in defining the first move of a contour.
