Research On CAPP In Digital Manufacturing Of Coupling

With the rapid development of information technology and its wide use in manufacturing,the building of enterprise information has entered a prosperous age. More and more enterprisers realize that it is very important to resolve such problems as releasing technologists from burdensome and repeated labor,managing a mass of technical files and data effectively,integrating with other information systems of an enterprise and so on.The application and development of CAPP has offered an approach for enterprisers radically.The CAPP is shortend form of computer aided process planning.The process planning is the first stage of preparation for manufacturing technical document.And it is the bridge between product design and product manufacturing.The process is the base of froch design,manufacturing,the method of machining and machining route.Its function is following:organizing produce,controlling quality,enhancing productivity,reducing cost,reducing produce periods,improving work conditions,etc.so,the process planning is the core part of production.In the mechanical industry,There are tens of thousands of types of mechanical parts and many ways of machining gears and a various kinds of machines,as a result the planning of the machining processing turn out to be especially important.The process gets more complicated partly.Because there are so many kinds of parameters have to be taken into consideration while machining,the other reason is that the process steps are sometimes complex,which makes it necessary to deal with a lot of related factors.so it is meaningful both theoretically and practically to establish such kind of expert system that will help to compile and check the file in terms of the parameters and the number of the parts.On the basis of the elaborating the basic technology of the CAPP system development and research dynamic at home and abroad,the paper Major research the CAPP on CNC machining technology.The study include:mechanical components design process;CAPP system research in decision-making process;database design of the CAPP system.Combined with the number of coupling components manufacturing process,in view of the practice of coupling enterprise considers, combined with small and medium-sized machinery manufacturing enterprises on the CAPP requirements,considering the practicality and advanced systems,while capitalizing on all the technology staff experience,staff developed a process can easily to carry out process design and process management,interactive coupling CAPP system.Through the implementation of the CAPP system,the technology staff can be able to standardize a variety of coupling products,process design,process design improve efficiency,to provide customers with optimal process design result.It greatly improves the efficiency of production,has good practical value.
