摘　　要：把微分几何中曲线与曲面之间的“切触”概念应用于高速机车流线型复杂曲面的数控加工 。In this paper an innovative theory for machining complicated surface is presented . By using a disc cutter instead of ball end miller , and adjusting the axis relative to the surface, the formed surface has the same curvature as the required surface ,up to as high as third order.

关 键 词：圆柱铣刀 三维自由曲面 三阶切触原理 高速机车
