THE WORKING TABLE DESIGN WITH HIGH SPECIFIC STIFFNESS FOR HIGH SPEED MACHINE TOOL

摘要

Working table is one of the moving parts in a high speed machine tool which requires high specific stiffness. Light weight and high stiffness are two goals in its design. In this paper, bionic principle was applied to design a working table impelled by electric linear direct driver in a high speed machine tool. The FEM result shows that the weight and the deformation of the new structure are both decreased compared with the original design under the same loading and constraint. This method can also be applied in the design of other parts of high speed machine tool.
