Five-Axis Carving and Milling Machine Modeling and Structure Optimization Design of the Welded Bed

Basing on the combination of the five-axis carving, the milling technology and the traditional machining technology, some parts of the design of five-axis carving and milling machine has been done and the three-dimensional model of the machine has been finished accordingly. This paper focuses on the whole structure modeling, the structural design of welded bed, the analysis and optimization. Because the welded bed is made of many steel plate welded, the strength of structure is weaker than the needed. Through the research of the welded plate, the strength of the machine can be strengthened if the bed is melded by different kinds of little steel plates around the bed. And by the analysis of the steel plate welded styles from different schemes, the optimal scheme can be presented to make sure the strength and stiffness.
