ABSTRACT OF THE DISCLOSURE: A method of controlling a press having a slide mechanism mounted for reciprocating movement, a press drive for cycling the slide mechanism and including a press drive shaft and means for driving the shaft at a controllable angular velocity, and an automated feed mechanism for transferring workpieces in and out of at least one work station in the press in synchronism with the reciprocating movement of the press slide, the method comprising the steps of driving the press drive shaft at a first, relatively fast angular velocity during a "closed" portion of each cycle of reciprocating movement of the press slide, the "closed" portion of each cycle including that portion of the cycle during which the press slide is working one or more workpieces, and driving the press drive shaft at a second angular velocity, slower than the first angular velocity, during an "open" portion of each cycle of reciprocating movement of the press slide, the second angular velocity being sufficiently slow to allow the automatic feed mechanism to transfer workpieces in and out of the work station in the press during the "open" portion of each cycle.
