Abstract：

Based on analyzing of geometry parameters of cross rolling pass,the contact curve of roller and pipe was obtained by using surface modeling and editing of 3-dimensional CAD.And the opening value of cross rolling pass,at any point of the rolling line,could be automatically calculated by projecting a curve to a surface along the normal direction of the surface.With the 3-dimensional CAD software—MDT(Mechanical DeskTop),the procedure of 3-dimensional graphic solution for opening value of cross rolling pass was given in detail through a practical design example.The problems existing in traditional calculation for opening value were overcome by using the approach mentioned above.This approach could shorten the design time and reduce the design complexity.It provides a simple,accurate and visual method of 3-dimensional graphic for cross rolling of pipes in industry.
