Abstract : The importance of the extrusion operation in the development of Air Force weapons systems was emphasized and the need for research in the area of extrusion lubricants was established. Experiments which were performed at the Air Force Materials Laboratory on various lubricants were discussed, and a unique system was devised to record the force transmitted to the die by means of a specially designed H12 tool steel load cell. This measurement in combination with the total load, as sensed by strain gages on the stem, enabled a dynamic evaluation of the role of lubrication in the container liner, the friction condition in the die, and the material's extrudability-all under various process conditions. These measurements were recorded during extrusions of OFHC copper at 800 F and of 1018 steel at 1800 F. (Author)
