Abstract
In this paper, the research focus on NC process information integration methods based on database and process information extraction from macro files of heterogeneous commercial CAM platforms. First, analyzed the macro file characteristics of studied CAM system to build heterogeneous systems variables mapping table and establish standard macro file for each studied CAM systems; Second, designed macro file self-learning mechanism based on characteristics of the macro file, extracted implicit process information in macro files and saved to build General process Database; Finally, used the General process Database and the standard macro files to generate target macro files to achieve automatic programming. The process Information integration method in this research improved the efficiency and processing quality of NC machining, and made excellent process experience well inheritance and reuse.
