가속도센서를 이용한 절삭공구 무선 상태모니터링 시스템 구현
Abstract
In this study, we implemented a wireless monitoring system by installing an MEMS accelerometer, an Arduino board, and a Bluetooth low energy communication module inside a tool holder, to monitor the tool condition during the end milling process. We measured the received signal strength in an actual work environment, using the antenna installation method for the wireless communication sensor installed in the tool holder.
The data was measured during idling and cutting, and the cutting waveform for each tool edge was detected. We confirmed that the developed wireless monitoring system can detect the cutting waveform of the tool during machining, in an actual work environment. Additionally, our wireless monitoring system is cheaper than existing monitoring systems.
