Optimization design and process improvement of horizontal machining center bed based on simulation

In view of the problem that the guide rail is too distorted during the assembly of a horizontal machining center bed and the horizontal adjustment cannot reach the accuracy and needs to be repaired, this paper compares the torsional and flexural static stiffness of the bed and analyzes the stability of the processing technology support by using the simulation software, through which the weakness of the bed in the structural design and processing technology support is found and the improvement scheme is put forward. This study provides a reference structure and method for the structure and high quality manufacturing process design of the bed of the same type of machine tools. The quantitative value of torsional and flexural stiffness of the bed obtained in the research process can also provide a reference value for the finite element analysis of the same type of machine tools.
