3510

No Machining Cycle Found (Figure Block Only)

Fanuc · Series 0i Manual Guide

What does 3510 mean?

This MC alarm (specific to Series 30i) indicates that the control system could not find a valid machining cycle to execute. This occurs when the machining program specifies only a figure block without the necessary accompanying machining type block, making the intended operation undefined.

Common Causes

  • A defined machining shape is present, but no active cutting command follows.
  • The program structure lacks the necessary commands for material removal.
  • Only geometric data (e.g., G02, G03) was found without a cutting feed (e.g., G01).
  • The controller requires a specific block type for machining initiation.
