Dynamic Structure Design of Large-Scale High-Speed Gantry Type CNC Milling Machine
To design a milling machine with high static stiffness and machining precision, the three-dimensional (3-D) model and the finite element model of a large-scale high-speed gantry type CNC milling machine have been established according to the demand of engineering. The main components of the milling machine have been studied separately by static and dynamic analysis to make an optimal structure design. The results indicate that the structure of the milling machine has great static stiffness, little structural deformation, and good dynamic characteristics. The method used in this paper provides helpful theoretical guidance to the dynamic design of milling machine.
