Real Time Sensing of a Chatter Badness for a Grinding Machine Line of Automobile Bearings using MBB(Machine Black Box)

머신 블랙박스를 이용한 자동차용 허브 베어링의 연삭가공라인 채터 불량 실시간 감지

The paper deals with the real time sensing of a chatter vibration in grinding machine line of automobile bearings using machine black box. The chatter vibration plays bad role in machining quality such as high roughness as well as tool life and machine failure. In this paper, the vibration signals of the automobile hub bearing in the grinding process are shown in the time domain and frequency domain. Through the vibrational signals, chatter vibration badness is detected using machine black box. Therefore, machine black box can be applied to the real time detection of the grinding process in engineering fields.
