Structure Optimization of Ultra-precision Machine Tool Guide based on Isight

摘要

The influence of the guide rail on the machining precision of the machine is great, and the optimization of the rail structure can improve the machining performance of the machine tool. Based on ANSYS Workbench simulation analysis, this study uses Isight to optimize the structure. The key dimensions of the rail structure are used to model the parameters and the optimal Latin hypercube test. The maximum deformation of the optimized rail is increased by 4.74%, but the quality is reduced by 3.91%, which satisfies the accuracy requirement. The optimization results verify the feasibility of the proposed method.
