摘要: 基于分形几何理论,通过分析机加工随机表面的轮廓谱矩和表面谱矩的特性,提出了一种各向异性表面的三维形貌的等方性评定参数。实例计算表明,精车加工表面是不等方性的,而平面磨削工件表面形貌的等方性较好。

Abstract: Through the analysis of the profile spectral moments and the surface spectral moments, a quantitative evaluation method is proposed, which is based on the application of fractal geometry theory. Using the 2nd spectral moments and fractal dimension, the isotropic evaluation parameter A of 3-D surface is presented. Experimental results indicate that the surface topography machined by finish turning is anisotropic, and the surface ground is isotropic.
