We usually put the ring with equipment generates increased diameter , wall thickness reduction processing technology called ring rolling . Compared with ordinary forging forming process , ring rolling process has the energy, materials , high production efficiency , low production costs, wide range of products and other major advantages . In the ring rolling process design process, the need for many process parameters selection and calculation. Traditional manual design efficiency and higher cost , and the strong dependence on personal experience . The emergence of CAPP system can be a good solution to this problem , ring rolling CAPP system can realize ring rolling design, analysis , manufacturing, automation and integration. CAPP system currently used a lot , Liu Yufeng developed ring rolling CAPP system is a platform based on VB and fuzzy mathematical theory developed by Intelligent Systems . However, the system due to various reasons there are still many shortcomings and deficiencies , but the system only developed rectangular cross-section ring rolling CAPP system , not comprehensive, system availability is not very good . Based on the study of Liu Yufeng CAPP system developed on the basis of actual production for the needs of the targeted improvement and perfection , while the introduction of three-dimensional finite element analysis software for inner and outer ring rolling process steps were simulated and analyzed , reached a practical level outside rough design. On this basis, the development of small and medium- ring rolled CAPP system . The new system is simple, practical, and not only for the rectangular cross-section ring , can also be used inside and outside the ring stepped section . The new system can call the Pro / E software automatically generates a three-dimensional model of forgings and drawings , automatically calculates the important process parameters , and the system is connected with the Excel software to realize the automatic generation of quotations . Compared with the traditional process , the new system can greatly save the ring rolling design time, improve design accuracy and efficiency.
