Finishing Not Possible

Fanuc · Series 0i Manual Guide

What does 3508 mean?

This MC alarm (specific to Series 30i) indicates that the specified conditions prevent the successful completion of a finishing operation. This implies that the finishing program contains parameters or commands that are incompatible or insufficient for the desired outcome, risking an incomplete or incorrect finish.

Common Causes

  • The final surface requires a high degree of accuracy not achievable with current setup.
  • Tool wear has progressed to a point where finishing is compromised.
  • Previous operations have left significant irregularities.
  • Machining strategy does not support the desired surface finish quality.
