Design and Research of the Structural of Cross-rail in the Planer Type Machines

The cross-rail is one of the main supporting parts of the planer type machines the quality of the cross-rail's structural can been directly affected on the performance of the machines and the cost of machining. In this paper the research is done about the form of rib and section the distributing of guide-way and the discussion is given about the form and the machinability of the cross-rail in the certain machine tools. By using the finite element analysis method the complexion of stiffness about all kinds of forms of the cross-rail guide-way distributing is contrasted.
