    초록 This paper shows that the identified and unidentified components of surface roughness in NC turning lathe which can not be analyzed in time domain such as Rmax, Ra can be isolated in frequency domain by FFT analyzer.
    By interfacing FFT analyzer with stylus surface roughness instrument, surface roughness on change of working condition, especially tool feed, such as 0.1, 0.15, 0.2, 0.25, 0.3(mm/rev) can be analyzed in frequency domain as follows.
    1. By frequency analysis of surface roughness profile, the basic wave length of surface roughness can be obtained to isolate the identified and unidentified components of surface roughness.
    2. With increase of tool feed, the unidentified components of surface roughness increase.
    3. Since Rmax, which can be obtained by stylus surface roughness is proportion to the output voltage of FFT analyzer, FFT analyzer also can be used to measure surface roughness in time domain such Ra, Rmax.
