A punch press ram drive is described in which a reversible electrical servo motor is coupled to a crankshaft having an eccentric journal driving a pitman arm connected to the ram. The electrical servo motor is operated by program controls so as to either cause rotation or oscillation of the crankshaft to drive the ram through various programmed stroking modes, in which punch position, velocity, acceleration, varying over the course of a stroke may be programmed.
