Title Computer aided design and manufacture of Link hip prosthesis of punch and die

Abstract

With the rapid development of mechanical automation , 3D modeling technology has been widely applied in various fields of life. This paper mainly introduces the design of human hip joint prosthesis of punch and die. At first introduces the artificial hip joint replacement of the current situation and research status at home and abroad. Then the features of SolidWorks software in 3D modeling and analysis of how to use SolidWorks to complete the 3D modeling design are shown in this paper. After that,design of punch and die manufacturing of hip prosthesis is completed through the mold's built-in SolidWorks. Finally complete the simulation of NC machining of punch and die.

Kinds of knowledge and skills are applied during the graduation design . Deeply research on 3D modeling technology and mechanical design method is done as well. And enhance my ability on use of SolidWorks proficiency.

Keywords 3D modeling Hip prosthesis punch SolidWorks CAMWorks
