Dimension Optimization of Machine Tools' Components

Light weight design without loss of stiffness may reduce the cost and promote the performance of machine tools. A new dimension optimization method is promoted to optimize the vertical slide of a horizontal machining center. The influence of the cross section dimensions to the stiffness and mass is analyzed. A program is compiled to search the minimum weight of the vertical slide with sufficient stiffness. Finite element analysis is used to validate the stiffness of the new design. The result shows that the method is effective in machine tools' components design.
