Research On Computer Aided Process Planning Of Coupling

In manufacturing, the types of parts are complex and diverse,the process parameters that parts` corresponding processing methods and processing need to be considered is "dazzling". The process of complex parts is more cumbersome and taking more time, therefore, it is particularly important to design rational and automated processing technology, which can take technologist freed from repetitive and complex work. CAPP(Computer Aided Process Planning, CAPP) technology can not only solve the problem but also achieve the design process standardization and automation.It is important for enterprises to shorten production preparation,improve manufacturing quality and optimize manufacturing resources. So for a specific industry, the development process of CAPP system can help designers to query, design and management parts has important practical value.First,this paper introduces the home and abroad research of CAPP technology.Followed by the development of CAPP system research expertise required, including: the description and input of parts` information,the process of typical mechanical parts, process decision methods of the system.After that establish the coupling process knowledge and technology database combined with actual production for the convenience of the CAPP calls.Finally, contraposing coupling manufacturer’s product variety and the actual production, taking into account the needs of small and medium sized machinery manufacturing enterprises to CAPP, integrated consider the practical and advanced of CAPP system, and learning the experience from technology staff s,using Qt language based on the coupling process knowledge and technology-based database, developing a interactive coupling CAPP system which can not only complete process design but also achieve process management.It designed to standardize the design of process of coupling products, improve efficiency of the process and production efficiency.It has good practical value.
