采用圆柱铣刀的不可展直纹面数控侧铣加工

The NC side milling of the ruled surface with cylindrical cutter

将切触原理应用于曲面加工。对不可展直纹面,按切触原理,确定当接触线不沿刀具直母线时,刀具的最佳姿态,并按三阶切触原理,确定刀具的最佳姿态和最佳接触方向,做到曲面三阶展开和三阶接触。

The concept of contact was applied into the machining of the complex surface. For the undeveloped ruled surface, with the theory of contact, the best cutter postural can be determined when the contact line not along the straight line of the cutter. And further more, with the concept of third order contact, both the best cutter postural and contact direction can be determined at same time.
