Design and Optimization of the X Direction Sideway Face Camber Curve of Super-Span Cross-Rail

Abstract:

As super-span cross-rail of NC heavy-duty planer type milling machine tool has a super span and heavy mass,it will deform seriously after installed. Machining an arch camber on X direction sideway in advance is used to compensate for influence caused by its deformation.Finite-element method is used to analysis deformation of super-span cross-rail when working.Multinomial is used to fit deformation curve based on deformation of the X direction sideway of cross-rail when bottom-slide and ram at each position.At the same time this paper takes into consideration of the impact on camber curve as the bottom-slides span brings about 2 deformation curves.A method based on 2 deformation curves is put forward to design and optimize the camber curve. By comparing various camber curves effect on the deformation of milling head,this article proves that the optimization method can effectively reduce the influence of cross-rails deformation on machine tools accuracy.
