Number of Cuts Exceeded Limit

Fanuc · Series 0i Manual Guide

What does 3504 mean?

This MC alarm (specific to Series 30i) indicates that the number of cutting operations specified in the program has exceeded the allowable limit. This can lead to excessive machining time or an attempt to perform more cuts than the system or part geometry can support.

Common Causes

  • Safety limit for tool engagement cycles has been surpassed.
  • Maintenance or operational limit for part production reached.
  • Machine control preventing further operations due to cycle count.
  • Program has incorrectly specified a very high number of repeats.
