Numerous billets of AISI 1018 steel at 1800 F and OFHC copper at 800 F were direct extruded on a 700-ton horizontal press in order to determine the effects of such process variables as reduction ratio, billet length, lubrication condition, and die angle on the forces involved in the operation. A unique measurement system was employed which quantitatively determined the deformation force of the die as well as the total required extrusion force on the stem. Author
