【Abstract】 We present a directed graph representation model to identify dimensional chains. Then we use dimensional chains to determine working dimensions and tolerances. Based on the methods mentioned above, a software was developed. It is programmed with Visual Foxpro 3.0, and has user friendly interfaces, it provides a tool kit to determine operation dimensions rapidly and conveniently for CAPP.更多还原
