Abstract

The invention relates to a five-axis numerically-controlled machine tool control method based on digital twins. The five-axis numerically-controlled machine tool control method based on the digital twins is characterized by comprising the steps of: 1, establishing a twin virtual model similar with a physical entity; 2, establishing a digital twin model of a five-axis numerically-controlled machinetool; 3, establishing a communication between the twin virtual model and the entity five-axis numerically-controlled machine tool in virtual simulation software; 4, establishing a processing and analysis system for twin data; and 5, enabling the five-axis numerically-controlled machine tool and the twin virtual model to keep twin information synchronization in real time. The five-axis numerically-controlled machine tool control method based on the digital twins is scientific and reasonable; data real-time synchronization can be carried out between the twin virtual model and the entity five-axis numerically-controlled machine tool; not only can simulation be carried out before machining, a scheme for solving problems can be timely found, a product machining effect can be predicted and theactual engineering operation is guided, but also a machining state can be monitored in real time and visually displayed in the machining process so as to timely find and correct problems of the machining link and improve machining efficiency.

Description

technical field [0001] The invention belongs to the field of industrial equipment automation, and relates to the real-time operation control, monitoring and analysis of digital twins of five-axis numerically controlled machine tools, and in particular to a control method based on digital twinned five-axis numerically controlled machine tools. Background technique [0002] With the development of the information age, digital twin technology has become one of the methods to realize intelligent manufacturing. The digital twin is to create a virtual model of a physical entity in the information space through digital means, and use the data to simulate the behavior of the physical entity in the real environment. There are relatively few existing control methods for CNC machine tools based on digital twins, and most of them are digital twin modeling methods for CNC machine tools. [0003] By searching the published patent documents, a published patent document similar to this pat...
