Invalid Machining Start Point

Fanuc · Series 0i Manual Guide

Hva betyr 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.

Vanlige årsaker

  • 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.
