对微观不平度10点高度Rz值计算方法的探讨

在零件表面粗糙度测量和精度评定中,通常的方法是用Rz参数反映零件表面粗糙度,虽然它是个最或然值,但作为精度分析来讲,它不能很充分的反映表面粗糙度的偶然误差特性,为此提出一种以观测值改正数求零件表面粗糙度的观测值中误差方法,它更能明确分出零件表面粗糙度同一系列中的差异.

On Micro Roughness Cross-height Rz-value Calculation

In roughness and precision evaluation,the usual method is to get the reflection components of surface roughness by Rz parameter,although it is a most probable value.But in the light of precision analysis,it cannot represent the accidental error characteristic of surface roughness.One kind of observed value error method is suggested,which can branch out the difference in components surface roughness.
