它介绍了表面粗糙度二维与三维功能参数,分析指出二维功能参数的理论缺陷以及三维功能参数的优点.由于三维功能参数尚未形成正式标准,它使用MicroXAMTM三维形貌仪及粗糙度样块进行试验研究,探讨其应用规律.结论如下:三维功能参数适用于普遍对象,以指数形式出现的三维功能参数是基于Abbott曲线的表面微观几何形状的描述,和表面的精度并无直接关系,对应周期性较强表面与随机性较强表面,其数值出现较大差异,随机性较强表面性能优越.%It introduced 2-D and 3--D functional parameters of surface roughness, also analysed their academic shortcomings and advantages. Be cause of 3-D functional parameters not being forms the formal standards experimental study was carried out by using the MicroXAMTM 3-D Surface Profiler and stan-dard examples of surface roughness.The results show that 3-D functional parameters apply to all ecumeni-cal engineering surface.lt describes the shape of surface roughness and have no relation to surface preci-sion, based on Abbott curve and in the guise of exponent.To periodic surface and random surface,the nu-merical value of 3-D functional parameters appears a greater difference.The random surface's capabilities is obvious advantage than periodic surface s.
