摘要：

This paper describes a method of generation of the free-form surface by the boundary integral equation using the polyharmonic function. This method requires boundary geometry of the free-form surface and the lines on the free-form surface, which are contour lines for example. The height of points on the free-form surface is calculated, after solving the discretized boundary integral equations. Several elements and their shapes, which are useful in this method, are shown. In order to investigate the efficiency of this method, this method is applied to the CAD for dies.
