| 摘 要： | 基于线接触的回转二次曲面加工方法,无需复杂的位置控制,能够加工在轴和离轴回转二次曲面,同时,用同一个刀具可以加工不同类型、参数的回转二次曲面,并且铣磨成形时定位误差和刀具轮廓误差对面形误差的传递系数都小于1。

| Abstract: | A fabrication technique of conic surface of revolution based on lin e-contact is presented. The shaping theory is analyzed with geometry method. Con ic surfaces can be machined based on this method without complex positioning con trol. Besides, in this method, one type of surface can be got with different too ls, inversely, one tool can machine different types of surfaces. The transfer co efficients between the shape error of the machined surface and the positioning e rror, shape error of the ellipse tool are all smaller than one. |
