This paper highlights a new noncontact technique to assess the differences in surface characteristics of components machined by shaping, milling, turning, and grinding processes. The method suggested here is a laboratory analysis based on the process of intensity Fourier transformation taking place on the surface under testing. The measurements are made on the spatial frequency spectrum of the ground surface as an example, using lasers, rather than on the image of the surface. The results are analyzed by using an in-process microprocessor system to evaluate the surface characteristics immediately.
