Research on the key Technology of contour error control of machine tool based on digital twin

Abstract

It is difficult to control the contour error machining with CNC machine tools. Aiming at this problem, a contour error control framework based on digital twin and digital twin interaction method were proposed. The method is based on the theory of digital twin, first built in the Ve2 multidimensional image modeling machine, then use data interaction model for digital twin body inside and outside information interaction, based on improved particle swarm algorithm to build the dynamic optimization model of pass through to the real time processing information of voice parameter to optimize the machine tool, the simulation under the reducer housing, for example, the effectiveness and feasibility of this method for contour error control of the machine tool are verified.
