Abstract：Through comprehensive comparison of domestic and foreign technology of wood engraving machine and five-axis CNC system, advanced five-axis engraving technology was used in the wood engraving machine. The 3D virtual modeling technology was used in the design of engraving machine beam, bed and other frame structure. The feed system of engraving machine and other functional components were designed. The static stiffness of gantry beam and other parts of engraving machine were optimized by using virtual modeling technology. Based on meeting the carving precision, the optimization of the mechanical structure was finished.
Keywords：wood engraving, mechanical design, feed system, stiffness optimization
