【Abstract】 According to the design and manufacture in the die of high tension electrical equipment insulator,this paper expatiates upon the true connotation of virtual manufacture technology which is based on product modeling data share and process simulation in CIMATRON environment. Furthermore, the paper expound the CAD/CAM technology on the basis of drawing which experiences the phase of curve modeling,surface modeling and solid modeling describing the geometry of product and gradually become feature modeling which is based on geometry form comprising of all information during design and manufacturing of product. The quality of die will be improved and the period of production will be shortened. Moreover,the important means of product modeling and data exchange is based on CAD/CAM technology.更多还原
