Abstract：

The surface data of the curved sheet must be analyzed in die CAD & CAM.The method of getting the surface data of the curved sheet is expounded.Flatting the three dimensional model,the center of the forming press is computed.At the same time,the way of treating the vane model is also described.A method for die design and automatic manufacturing is proven.
