摘　　要：零件表面三维形貌受生成机理的影响,与表面功能密切相关,对表面的功能评定至关重要.本文论述了三维表面功能评定的各种方法;介绍了小波滤波技术在表面功能评定中的应用,重点提出了表面粗糙度的提取新方法,用小波分析方法确定三维表面粗糙度评定基准面,能精确地把表面粗糙度与表面其他成分分离,从而提取表面粗糙度.最后给出了一些实验结果与分析,指出了小波滤波技术在应用中存在的问题.The 3 - D surface shape appearance and surface function are go hand in hand, because of generating mechanism effect. It is all -important for surface function evaluation. This article discusses the various method of the 3 - D surface function evaluation; introduces wavelet filtering technology application to evaluation of surface function, especially to new methods of getting the surface harshness. Using wavelet analysis, we can ascertain the criterion of 3 - D surface evaluation, exactly separate the surface harshness from other components. Thereby we get the surface harshness. Finally, this article gives out some result and analysis of experiment, And point out that there exists problem in the wavelet＇ s wave - filtering technology in application.
