摘　　要：通过对椭圆封头的几何特征和数控加工工艺进行分析,得出其制造难点在于控制内、外曲面等壁厚达到要求,通过求解内、外曲面轮廓的参数方程,并对不同数控编程方法进行分析,得到该椭圆封头的数控加工及数控编程方案,解决了该椭圆封头的数控加工问题。Through the analysis of the geometric characteristics and numerical control processing technology of the elliptical head,it has been found that the difficulty of its manufacturing lies in controlling the wall thickness of the inner and outer surfaces to meet the requirements.By solving the parameter equations of the inner and outer surface contours,and analyzing different numerical control programming methods,the numerical control machining and numerical control programming scheme of the elliptical head has been obtained,and the numerical control processing problem of the elliptical head has been solved.
