The Cad System Developed In Three-dimensional Cam Mechanism

Along with the information era and the advent of the global integration process, China's machinery manufacturing enterprises must to possess the capabilities of the rapid development products,development and the innovation in order to survival and to development in the fierce competition market.Due to Cam' s unique features,.It has a wide range of applications in various fields of the industrial engineering.The Cam mechanisms are not the same in the different application environments which is decided by the feature of the cam mechanism.Therefore It's will lengthen the product design cycle,design cost and reduce the enterprise competitive power if we carry on the redundant design and the computation to a single cam gear which will increases the massive duplicated work for the designers.Practice has proved that 3D CAD technology played a key role to speed up the product development,to shorten the product design cycles,to improve the product quality and to reduce the costs.All aboved is a powerful method which will support enterprises to enhance their innovative design and to improve their market competitiveness.In order to meet the requirements of the industry and according to the habits of the Chinese designer,we establish the 3D CAD system of Cam which is based on the SolidWorks and through the use of the secondary development of SolidWorks interface.This article discusses the application of the Cam,the trend of its development, development of the CAD technology,describe the function of the SolidWorks software,point out the necessity of the secondary development of SolidWorks and the secondary development methods.The article discusses the three-dimensional modeling techniques in detail and defined the system's design philosophy by the parameters of the feature-based modeling technology.This article focuses on the key technologies of the created SolidWorks API application which is base on the Windows platform in the VB environment,3D CAD disc Cam system is development by the Visual Basic which is based on the SolidWorks and introduce the system development of the relevant content.This article seeks to reserach and discuss the technology of SolidWorks secondary development deeply.In particular to provide the reference of the CAD system design for related institution.Its theory also applies to other secondary development of the CAD software.This article do be a good reference to the CAD/CAM practitioners and the technical personnel.
