Development Status and Technical System Framework for Smart Machine Tool

Abstract

Smart machine tool has become the development trend of machine tool equipment. After the introduction on the research status of smart machine tool at home and abroad, three major issues of smart machine tool technology are analyzed, followed by the narrow and broad definitions of smart machine tool. Then eight smart technology features are given, including human-computer-machine synergy, overall-local coordination, smart appropriateness and endless, self-learning and its ability to continue to improve, unity of autonomy and centralized, structural openness and scalability, green characteristic of manufacture and process, penetrability of intelligence, and the characteristic and interrelationship of intelligent functions are described, which contain people-centered human-computer-machine dynamic interactive function and three basic intelligent functions, including implement, preparation and maintenance. Finally, the theoretical framework is established, supported by eight theories and technologies, including human-computer-machine integration and fusion, perception of multi-source information, intelligent decision-making, intelligent implementation, intelligent maintenance, comprehensive ability evaluation of smart machine tool, standardization of smart machine tool, supporting technologies of smart machine tool and so on. Thus, the technical framework of smart machine tool has been formed, and it will be enriched constantly with technical progress and deep application.
