摘　　要：为实现零件加工时的自动装夹分组及定位面、装夹面的自动选择,从定义特征、加工面、装夹方案及它们之间的关系出发,采用聚类的思想求解装夹规划问题.在划分加工阶段的基础上,提出用"找相同元素法"获得刀具进入方向(TAD)相同的特征组合.对特征——TAD矩阵做变换,得到TAD可行解,进一步对TAD可行解寻找装夹面、定位面,并生成装夹可行解,即可形成装夹方案.以CATIA平台为基础,用CAA开发软件验证了该方法的可行性.该方法对实现零件的装夹分组有重要作用.To automatically identify the locating surface and clamping surface for setup planning of machining process, cluster method is used to manipulate the relations of machining feature, machining surface, clamping and to solve the setup planning problem. We put forward the finding same element method to find out the TAD feasible solution. Firstly, the feature-TAD array should transform to get TAD feasible solution. Secondly, find out relevance face and work out the clamp feasible solution based on TAD feasible solution. Finally, on the basis of CATIA platform, software development using CAA and verify the feasibility of this method. This method is important to realize the clamping block.
