摘要

为了更直观地获取样块表面三维轮廓的粗糙度信息，以衡量所测试零件的表面质量，进而衡量其加工工艺的优劣以及能否满足设计要求，研究了一种表面三维形貌的评定方式。利用白光相移干涉系统测量标准样块的表面三维轮廓数据，建立高斯评定基准面并提取粗糙度数据，数据处理后对最为重要的幅度参数和综合参数加以计算，分析各个参数所反映的表面三维结构特征，并对标准样块的表面形貌进行了全面综合分析。实验结果显示，均方根偏差与粗糙度的比值为1.04，表面十点高度为0.059

m，偏斜度大于0，陡度小于3，均方根斜率为2.993

m，表面峰曲率算数平均值为0.181

m。该实验结果符合研磨样板表面轮廓的分布特征，并且与用轮廓仪的测量结果相符。

Abstract

To directly capture the roughness of the three-dimensional surface profile for surface quality evaluation of the tested parts

thus weighing its processing technology and whether relevant design requirements are satisfied

an evaluation method for the three-dimensional surface profile was put forward. Relevant data on three-dimensional surface profile of the standard sample piece was measured by using the white-light phase-shifting interference system. Then the Gaussian reference plane was set up and the roughness data was extracted. The most important parameters such as amplitude and integrated parameters were calculated after data processing

for analyzing structural feature of the three-dimensional surface reflected by each parameter. Finally the surface profile of the standard block was analyzed comprehensively. The results show that the ratio of the root-mean-square deviation to roughness is 1.04

and ten-point height of the surface is 0.059

m; the degree of skewness is greater than 0 and gradient less than 3; the root-mean-square(RMS) slope is 2.993

and average curvature of roughness peaks is 0.181

m. The experimental results conform to distribution characteristics of the surface profile of the grinding template

and in consistence with the measuring values by contourgraph.
