Research on Machining of Elliptical Thread Parts Based on NC Turning

针对在椭圆曲面上加工圆弧螺纹的车削难点,进行数学模型的深入分析,通过车削圆弧螺纹的应用实例,来介绍车削圆弧螺纹采用宏程序编程的基本思路、方法和步骤,圆弧螺纹牙型轮廓满足圆的方程表达式,加工方式使用螺纹牙型轮廓满足二次曲线的异形螺纹加工,最后通过机床实际加工来验证编程思路的正确性。

Aiming at the difficulty of turning the circular arc thread on the elliptical surface, the mathematical model is analyzed deeply. The basic idea, method and procedure of macro programming of turning arc are introduced by turning the application of turning arc thread. The contours of the arc thread are rounded to satisfy the equation of the circle. The machining method uses the thread profile to meet the quadratic curve profiled thread processing. Finally, the correctness of the programming idea is verified by the actual machining of the machine tool.
