【Abstract】 Motif method is a new assessment method of surface topography. By setting various threshold values, surface roughness can be separated from waviness. The method stresses large peaks and valleys of the surface profile and selects important profile characteristics, but ignores those unimportant in topography assessment. Firstly, the parameters and combination conditions of 2D- Motif are discussed. Then, the definitions, parameters, and algorithm of 3D-Motif are summarized. Finally, some problems worthy to be studied in spreading the method are proposed in this paper.更多还原
