摘　　要：本文介绍金属板料数字化成形的方法 ,这是一种用CAD模型直接驱动 ,实现设计与制造一体化的柔性快速成形方法。其采用快速原型制造技术的“分层制造”思想 ,将复杂的三维形状分解成一系列二维层上的数据。并根据工件的几何形状信息 ,用三轴数控设备控制一个成形工具头作三维曲线运动 ,逐层对板料进行塑性加工 。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.
