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.

Abstract: A detecting and suppressing control method for milling tool chatter. Milling parameters are defined. A milling device is initiated using the milling parameters. Milling signals are extracted using a sensor installed on the milling device. It is determined whether chatter relating to the milling device occurs, comprising determining whether the milling signals are high frequency signals, and, if the milling signals are high frequency signals, determining whether signal points generated based on the milling signals are located in a stable area derived using a sliding function. When the signal points are located in the stable area, the milling signals are stable milling signals. When the signal points are located outside the stable area, rotational rates of a spindle of the milling device are adjusted.
