| Abstract: | The paper introduced the sheet metal digital forming process. It is the flexible rapid manufacturing method using CAD model to directly drive to realize the reunification of design and manufacture. It andapts the theory of “Layered Manufacturing” of Rapid Prototyping(RP) technology, dividing the complicated 3D shape into a series of 2D layer data.According to the geometry dimension information of the workpiece,use three\|axis numerical\|control facilities to control a molding tool to do the relative three\|dimension curve action,and to press the sheet metal along its action mark layer by layer. By this method, the sheet metal is steadily formed into the needed automobile covering parts. |
