摘要: 根据CAPP系统人机工程和工艺路线方案选择的需要,提出了一种基于图形控件和过程网的多工艺路线可视化设计与评估方法.该方法根据工艺路线的构成要素,设计建立了具有标示、工艺、图形和评估四个方面属性的工序控件、机床控件、特征控件和搬运控件等图形控件,采用图形控件的拖拽方式和网络图的表达方式构建工艺路线,实现了多工艺路线的可视化设计,并采用Dijkstra算法对过程网中的多条工艺路线进行评估,从而选择最优工艺路线.最后给出了某飞机结构件的应用实例.该方法能够更好地体现工艺师的设计思路,有效地进行工艺方案论证和决策.

Abstract: To meet the requirements of human machine engineering and alternative selection of process routes in CAPP, an approach to visually plan and estimate the multi-process routes based on graphic components and process nets was put forward. According to the elements of process route, common and typical graphic components including operation component, equipment component, feature component and transfer component were built, and these components were represented by four kinds of attributes: identification, display, technology and estimation. Thus, process routes were constructed by dragging graphic components and were presented by process net so that multiple process routes can be planned simultaneously and visually. Dijkstra algorithm was adopt to estimate the performance indexes of the multi-process routes, and to select the optimal process route. An application example for panning the process routes of an aircraft structural part was illustrated. The approach proposed is able to properly present the process planer’s intents and effectively carry out analyses and decision-makings for planning process routes.
