A hydrodynamic lubrication theory is developed for a generalized hydrostatic extrusion and drawing process with augmentation and back pressure. The die is assumed to be conical and uniform deformation and isothermal lubrication conditions are assumed to exist. The theory is in good agreement with experimental data previously published by other workers.
