Abstract
In this research, for retaining the machining information such as machining features and machining strategies, the ISO 6983 NC data are analyzed based on a next-generation CNC control language (ISO 14649) which contains the machining information explicitly. In previous report, the method for grouping tool paths from ISO 6983 NC data based on geometric information of the tool path was proposed. In this report, the grouping method for a multistage machining using type of group and motion direction of tool paths is proposed, and the software to display extracted machining information with an expertise is developed. The machining information is integrated, retained on the machining database, and displayed by the software.
