Monitoring of Milling Process with an Acoustic Emission Sensor.

Automatic monitoring of cutting process is one of the most important technologies for increasing the stability and the reliability of unmanned manufacturing system. In this study, the methods which use acoustic emission (AE) signals are proposed to monitor chatter vibration, tool wear and cutting edge breakage in the milling process. All experiments were conducted on an NC-vertical milling machine. The ball endmill cutter with 2 cutting edges and the square endmill cutter with 4 cutting edges were used. Using these equipment, the single-sensor monitoring system was constructed.
