“…The grinding process can be optimized more effectively with research of the effect of grinding process on the surface quality for precision components, such as ball screws pair, linear guide pair and rolling bearings, etc. from the perspective of the surface topography [4], [5]. Moreover, the microstructures such as pits, bulges and scratches in surface topography are the key factors influencing the thickness of the lubricant film and the friction and wear features for the friction pair surface [6]- [8].…”

Due to the limitations on the size and properties of samples, most of the surface topography tests are destructive and the contrast test of the surface morphology before and after friction and wear of the same workpiece cannot be carried out by the topography instruments. In addition, the destructive test increases the test period and the research cost, as well. In order to solve the above problems, a non-destructive surface topography measurement method is proposed in this paper. The 3D surface topography model of the workpiece surface can be established by the processing of the surface height distribution characteristics obtained by the surface profiler. It includes the discrete point reorganization, concentric processing, moving average filtering, equal length processing and other pre-processing and the post-processing like regression analysis, polynomial interpolation. Compared with the surface topography obtained by the topography instrument, it is found that the 3D surface topography model established not only characterize the surface features such as dents, bulges, and scratches accurately and effectively but also avoid the complex sample preparation processes. What is more, the surface topography of the workpiece can be acquired without destructing and the comparison test of the surface topography before and after friction and wear of the same workpiece can be conducted.Wencheng Tang received the B.S. degree from Nanjing Institute of Technology in 1982, the M.Sc. and the Ph.D. degrees from Southeast University in 1987.
