Application of CAD/CAM Technology on the Modeling of Freeform Surface Parts

摘要

To improve the design of complex curved parts and the shortage of reading two-dimensional drawings.This paper explicitly discussed modeling the bottom of a bottle by enhanced modeling and rendering techniques of CAD/CAM.Established the bottom with freeform surfaces in UG to solve the problem of design a part with freeform surfaces,and rendered the bottom of the bottle to express the result of three-dimensional stereoscopic of a part with freeform surfaces.Rendering is setting the material and texture for the model,and then adding lights and setting the background,etc to help solving the problem of identifying a part with freeform surfaces.Finally,we got the features of UG,the advancement,applicability of CAD/CAM and the necessity of expanding it.
