【摘要】 提出了零件面向对象的特征模型及其ODL描述方法,给出了描述的存储结构和零件特征的面向对象存取方法;构建了零件的AOVN网,实现了其机械工艺规程的CAG;通过构造AOEN网,可找到零件的关键工序,从而为有效地控制零件工艺周期创造条件.更多还原

【Abstract】 Firstly this paper gives an object\|oriented model and its description method for the parts, and then it provides a physical structure for the model, moreover it has built up a model called AOV network to implement the procss planning by CAG, finally it puts forward a method to find out the key process which greatly helps to control the manufacturing period by using AOE network model.更多还原
