Abstract
An electronic control system for operating the hydraulic cylinders associated with a press brake wherein independent control of each of the hydraulic cylinders is achieved to insure that the cylinders track against a fixed reference to insure more accurate forming of the workpiece. The cylinder tracking is under computer control which also establishes a creep speed slower than the normal forming speed near the point of ram reversal. A plurality of press brake may be operated simultaneously from the same tracking reference.
