针对平面度误差统计特征识别的问题，以条件概率和全概率为理论依据，提出由平面到直线再到平面的研究思路。采用三坐标测量机对某两个零件实际平面进行提取实验，通过对实验数据的分析和处理，对其平面度误差统计特征进行识别。经过检验方法计算验证，结果表明，在工艺系统稳定的情况下，加工出来的工件表面的平面度误差呈现正态分布的特征。

To the characteristics of flatness error identification problem,a research idea is put forward by the plane to the line and then the plane based on conditional probability and the probability theory.The actual planes information of two parts is extracted by the experiments using a three coordinate machine.Through the analysis and processing of exper-imental data,the flatness error statistical characteristic is identified.After the verification of the test method,the results showed that flatness error of the work piece surface exhibited the characteristics of a normal distribution under the stable processing conditions.
