Standardized Database Of Cnc Machining Parameters

With the prevalent application of advanced NC machines and the development of CAPP towards intelligence, many enterprises are facing an urgent problem of how to select proper tools and optimum cutting parameters in NC machining process planning and application. As an important part of CIMS, the management system of tools & machining parameters gets new chances and challenges.Through the project of the standardization of cutting parameters and tools parameters m NC manufacturing of aircraft slructural components, this dissertation analyzed and researched the problems concerned the standardization of the tools, which directed at the common materials and typical features of the parts. The crucial issues, which include the organization scheme of tools information in database, the recommendation of tools and machining parameters, are mainly discussed.Based on the above, cutting tools databases are built up, and experts system is used in tools selection. And then cutting parameters selection and optimization of end-mill in NC machining are researched deeply. In server, Oracle 7.3 is adopted as the database management system, while Delphi 5.0 is used as the development tool in client. At last, the dissertation introduced the integration of network and database, and realized cutting tools information sharing with Internet by means of ASP.
