Development of Basic System to Construct Database of Machining Know-how

Abstract

This paper presents an automatic database construction system of machining know-how for automatically outputting advanced NC programs from CAM (Computer Aided Manufacturing) systems. A problem of existing CAM system is that NC programs do not consider not only differences in cutting conditions such as machine tools, but also taste of experienced engineers. To solve this problem, this study proposes a system to construct a database which hierarchically organizes cutting blocks, machining features, cutting methods and cutting conditions by downloading the machine tool control parameters via the Internet and NC programs which are popular at the manufacturing site.
