把微分几何中曲线与曲面之间的“切触”概念应用于流线型复杂曲面的数控加工,提出用圆柱铣刀和圆锥盘铣刀的外圆在五坐标联动中加工三维自由曲面的最佳切触条件。利用曲线与曲面之间可以比曲面与曲面之间贴合得更紧密的特点 ,把微分几何里的曲线与曲面之间的“切触”概念应用于曲面数控加工
The concept of “touch-in” between curves and surfaces in differential geometry is applied to the NC machining of streamlined complex surfaces. The best method of machining a three-dimensional free-form surface with a cylindrical cutter and a conical cutter in the five- Touch conditions. By using the characteristic that the curve and the surface can be closer together than the surface and the surface, the concept of “touch-in” between the curve and the surface in the differential geometry is applied to the surface NC machining
