摘　　要：为掌握直线度误差对象的统计特征规律,通过构建在视频测量仪器上实现对某零件表面直线度误差测量坐标点的采集,将坐标点数据导入MATLAB软件中做出统计直方图,得出直线度误差近似服从正态分布的规律.采用统计学的正态性D检验法对直线度误差数据进行检验,得到零件表面直线度误差统计模型服从正态分布规律的结论.In order to master the statistical characteristics law of the straightness error object,this paper realizes the collection of straightness error measuring coordinate points of a certain part surface by the building video measuring instrument.Then import the coordinate points data to MATLAB software to make statistic histogram.From the statistic histogram,it is obtained that the statistical model is approximately obedient to normal distribution.Using the method of statistical D-normality test to test the straightness error data,a conclusion is pointed out in the research that the surface straightness error statistical model is normal distribution.
