摘要： 机械零件的表面粗糙度对零件性能有很大影响[1],因此对零件表面粗糙度的研究一直受到广泛的重视.由触针式轮廓仪测得的表面轮廓中包含了三部分的信息,即表面粗糙度、表面波度和表面宏观形状,为了客观地评定表面粗糙度,必须将粗糙度信号从轮廓信号中分离出.

Abstract: The problem of the filtering technique for three-dimensional surface topography is dealt with in this paper. The frequency characteristic of the two-dimensional digital filter which is used to filter the three-dimensional surface topographic signal is analysed and derived. The corresponding high pass and low pass digital filters are designed. Finally, a grinding surface is measured and the topographic signal is filtered respectively with high pass and low pass filters.Thus,the three-dimensional roughness and waviness are obtained.
