Abstract: This application with ESPRIT software has been developed in the work shop of the mechanical department of INSA-Lyon. Because of the usual use in education and in industries of many CAD software systems such as Catia, Pro Eng, IDEAS etc., was decided 3 years ago to implement a powerful CAM software system completely independent of these. The objectives were: friendly data communication with CAM system; to increase the development of applications in the production and manufacturing fields; to develop formation and training for education and industries with the help of information and communication technologies. This paper rapidly presents the implementation and the actual exploitation. In paragraph 1, ESPRIT software and the used functions are presented. The CAM formation of the INSA mechanical engineers is detailed in paragraph 2. The paragraph 3 presents the future developments. The KBM (Knowledge Based Manufacturing) function is described so as his use for the process planning. To conclude, the benefits expected for education and industry with virtual machining and e-manufacturing are highlighted.
