주파수 분석과 시계열 해석법을 이용한 밀링공구 마모검출에 관한 연구 = The study of tool wear detection used frequency analysis and Time-series in milling

다국어 초록 (Multilingual Abstract)

The detection of tool wear in cutting process is very important because tool wear have an effect on safety of machine structure, cost and precision of workpiece. During cutting one of the indirected tool wear detection technique is used to develop methode to detect the tool wear conditions. The cutting force signals varied with the cutting condition and tool wear are analyzed by FFT (Fast Fourier Transform) and Time-series. In-process detection of tool wear can be possible by observing the amplitudes of a specific components of cutting force in frequency domain.
