Abstract

Cross-rail is a key component of support structure of the machine, whose mechanical properties have direct impact on the accuracy and dynamic performance of the machine. This paper studied a bridge type milling composite extrusion CNC machine whose cross-rail welded together by a rib structure, therefore, well-designed rib structure is particularly necessary. In this paper, the finite element method for analyzing the cross-rails of four different rib structures, static deformation and natural frequency, and the deformation of impact on the process of start and stop in three performances are adopted to obtain better overall performance rib structure to meet the requirements of the mechanical properties of the machine.
