Abstract
Technical information, such as machining features, type of machining operations and machining conditions, should be represented explicitly and integrated into one data structure with some relation between the information in order to manage, modify, and verify NC data and avoid human error. However, traditional NC data (ISO 6983) contains such kind of technical information implicitly. In this research, technical information is extracted from NC code, and the extracted technical information is transformed into a next-generation CNC control language (ISO14649) which contains the technical information, and the ISO 14649 data are stored in XML.
