Exploration of software process method in CAD/CAPP/CAM integrated

Waterfall model and unified process are two methods,which are often used in the course of software development. In this paper, combining CAD/CAPP/CAM integrated study, the advantages and disadvantages of this two methods are analyzed,and increment iteration is presented based on unified process and referenced waterfall model. Accomplished assignment and achieved purpose in every of stage are set. Problems to be paid attention to in practice are proposed.
