一种面向工艺规划的零件分类和识别方法：采用零件工艺相似系数对零件实现分类。类似K-means的聚类算法。-Part classification and recognition method for process planning: the classification of parts by the process similarity coefficient. A clustering algorithm similar to K-means.

最终的权值矩阵就是滤波器的系数，模式识别中的bayes判别分析算法，基于欧几里得距离的聚类分析。- The final weight matrix is ??the filter coefficient, Pattern Recognition bayes discriminant analysis algorithm, Clustering analysis based on Euclidean distance.
