Abstract
NC data analysis is one of the efficient methods for acquisition and retaining the machining knowledge. However, code interpretation of actual NC data (ISO 6983) differs among CNC controllers. Typical examples of interpretation difference are fixed cycle orders which are significant for the machining of hole feature. Thus, it is difficult to analyze actual NC data directly. In this research, for obtaining the machining knowledge, actual ISO 6983 NC data is transformed into a next-generation CNC control language (IS014649) which contains the technical information. In this report, the method for extracting Workingstep which consists of Machining feature, Machining strategy from NC code depending on the controller based on Form-shaping function is described.
