三维机加工工序模型的变更与维护方法
|
摘要
针对三维机加工工序模型在变更过程中数据维护困难的问题,提出一种基于变更传播模型和工序模型信息的三维工序模型变更与维护方法.首先,通过建立工艺路线中各加工特征间的设计结构矩阵(DSM),分析各加工特征可能的传播路径;然后,以分析所得路径为核心,对可能受影响的加工特征、加工特征所属工序模型等信息进行结构化存储;最后,结合工艺路线中各工序的工序模型信息,提出添加、删除、修改加工特征的工序模型变更和维护算法.实例验证表明:该方法可有效地进行三维机加工工序模型的变更与维护.
In order to solve the problem of difficult data maintenance in the process of the 3 D machining process model, a method of change and maintenance of 3 D process model based on change propagation model and process model information was proposed. First, by established the design structure matrix(DSM) among each machining feature in the process route, the possible propagation path of machining characteristics was analyzed. Second, taken the paths of analysis as the core, the affected information, for example the information of processing features and process models that may be affected, are structured storage combined with the process model information of each process. Finally, a process model change and maintenance algorithm to add, delete and modify machining feature is proposed based on process model information. The examples show that this method can effectively change and maintain the 3 D machining process model.
