Abstract

Abstract: Aiming at the poor virtual-real interaction ability, single data presentation mode, and hysteretic abnormality handling in CNC machine tool status monitoring, a visual monitoring method for machine tool process based on digital twin is proposed, Which realizes the mapping of three subsystems of machine tool, machinery, control and electrical to the information space from three dimensions of geometry, logic and data. The verification of instructions and CNC programs, real-time status monitoring and abnormality handling during operation are carried out. A digital twin-based machine tool modeling and monitoring system is designed and developed. Taking a five-axis CNC tool grinder as an example, the feasibility of the proposed method is verified, Which can effectively improve the virtual-real interaction ability of machine tool, degree of data visualization, and the efficiency of abnormality monitoring and processing.

Key words: digital twin, digital twin machine tool, modeling, status monitoring
