The head of a steam generator consists of several parts with different structures. Machining of a large circular arc surface and the inside and outside of the ellipsoid is a difficult task. This paper discusses the problem of manufacturing large parts in the steam generator oval head. By analyzing the part structure and technical difficulties, a manufacturing process and the main operation procedures are proposed, which include parametric control machining treatment. The process can give good results, confirmed by inspection on the manufactured thickness.
