The design and implementation of a minicomputer control for a ship frame bending machine is described. This project automates frame fabrication by using cold-forming four-point bending techniques. The control software can accept data produced by the AUTOKON computer system and can automatically account for springback and for errors in bending or feeding by a self-adaptive algorithm. The Case Western Reserve bending system incorporates state-of-the-art computer technology to upgrade the beam bending operation to a faster and more accurate process that is free of many previously unavoidable human errors. The machine also employs principles of mechanics, made practical by the improved electronic control, that produce a structurally superior bend. Although beam bending represents a small fraction of the total costs of shipbuilding, the potential exists for reduced construction costs throughout the ship assembly process. Potential applications of this system are in no way limited exclusively to shipbuilding.
