Invalid Cutting Conditions

What does 3507 mean?

This MC alarm (specific to Series 30i) indicates that the cutting conditions specified in the machining program are invalid. This often involves parameters like feedrate or spindle speed that are outside acceptable ranges or are incompatible with the current operation, preventing safe and effective machining.

• The combination of cutting speed and feed rate is unsafe or inefficient.
• Programmed coolant or lubrication settings are incorrect.
• Chip load per tooth calculation is outside optimal ranges (e.g., P7-15).
• Attempting to use a finishing pass setting for a roughing operation.

   Modify the machining program to specify normal and valid cutting conditions, such as an appropriate feedrate for the operation.
