1. A dental milling system comprising:

  • a first milling tool for milling a dental prosthetic;

    a first spindle operable to receive and fixedly engage the first milling tool, the first spindle further operable to rotate the first milling tool when the first milling tool is received by and fixedly engaged with the first spindle;

    a first accelerometer positioned adjacent to the first spindle and operable to detect vibrations associated with rotation of the first milling tool; and

    a processor in communication with the first accelerometer to receive data sets representative of the vibrations detected by the first accelerometer, the processor operable to process the data sets to identify changes in one or more harmonics of the detected vibrations indicative of a break of the first milling tool.
