Abstract
A computer assisted detecting and restraining system for cutting tool chatter. The system comprises a network monitor system, a signal extraction system, a chatter detection system, and a chatter restraint system. The network monitor system monitors a machine tool and receives audio caused during a cutting process. The signal extraction system extracts vibration displacement signals generated during the cutting process converts the vibration displacement signals to digital signals and transfers the digitalized signals. The chatter detection system receives the digitalized vibration displacement signals and sends a control command when the signals are high frequency signals. The chatter restraint system receives the control command and adjusts rotation rates of a spindle of the machine tool accordingly.
