The measurement of the amount of wear by using least squares approximation with Fourier series

푸리에 급수와 초소 자승법을 이용한 마멸량 측정

A method of calculating wear amount which is based on digitally measured surface profile was suggested. The original profile of worn out profile was estimated from its adjacent surface profile by using least squares curve fitting with Fourier series. The approximated curve was well fitted to original surface profile. With this approach, more accurate calculation of the wear amount will be possible.
