 note = {When a dual phase metal is ground, which is composed of the soft matrix and the hard second phase, ground surface roughness is affected by the shape of the second phase. Ground surface roughness is characterized by autoregressive model and is analyzed by power spectrum.\nComparing power spectrum of globular pearlite with that of lamellar perlite shows that lamellar pearlite gives higher power spectrum value. It indicates that ground surface roughness of globular pearlite is better than that of lamellar pearlite. As grain size of a wheel changes from #60 to #120, the ground surface roughness of lamellar pearlite is considerably improved.\nSo the power spectrum is applicable for estimating ground surface roughness with more accuracy than the traditional method., 紀要論文},
