Abstract : Using funding appropriated in FY79 preliminary engineering was conducted to examine the present methods used in the manufacture of split rings. This report is the culmination of an effort to examine the present methods of manufacturing split ring breech seals and to establish new manufacturing procedures and equipment to improve the quality and lessen the high rejection rates experienced using the present methods of machining. Initial engineering analysis revealed that the manufacturing difficulties experienced are predominant in three machining operations: (1) kinking; (2) Splitting; and (3) Polishing the split surfaces. This report addresses those areas.
