圆弧形内螺纹的包络法加工

Envelop Method Machining of Circular-arc Inner Screw Thread

针对圆弧形内螺纹加工的传统方法,并从实际生产加工出发,提出了包络成型法的加工方法,建立了加工的轨迹曲线方程并求得最大误差。新的加工方法,验证了理论分析,提高了加工精度和生产效率,降低了劳动强度,达到较好的预期效果。此加工方法已在实际中得到应用。

According to the machining method of a circular-arc inner screw thread, and form actual production processing conditions, this paper has put forward the envelope method of forming process, established the machining trajectory curve equations and obtained the maximum errors. The new method has validated the theoretical analysis, improved the processing precision and production efficiency, reduced labor intensity and reached a better-expected effect. The processing method has got application in practical.
