The objective of this program was to provide an improved method of manufacturing military gun barrels ranging in bore size from .22 to .50 caliber. During this project, suitable equipment was purchased, and a pilot line for cold rotary forging of barrels was established. Excellent bore qualities, reproducibility, reduced process time and reduced tooling costs were demonstrated. By rifling, chambering, and simultaneous exterior contouring, many conventional machining operations were eliminated with a gain in production rate. The cold rotary forging of gun barrels has been implemented as a production process for the Rock Island Arsenal. Greater utilization will occur when engineering design is more closely correlated to the manufacturing process.
