Abstract
Methods, systems, and devices for monitoring tool breakage and wear in a dental milling machine are provided. In one embodiment, a dental milling system includes a milling tool for milling a dental prosthetic and a spindle operable to receive, fixedly engage, and rotate the milling tool. A first accelerometer is positioned adjacent to the spindle and is operable to detect vibrations associated with rotation of the milling tool. A processor is in communication with the first accelerometer to receive data sets representative of the vibrations detected by the first accelerometer. The processor processes the data sets to identify changes in one or more harmonics of the detected vibrations indicative of a break of the milling tool.
