ABSTRACT:
A press brake control system and apparatus including a vertical ram extension controller and back gauge system which together determine respectively the angle and location of successive sheet metal bends according to a stored operating sequence. The control system and apparatus is attached to an existing and unmodified press brake to which the press brake control system automatically adapts its control functions according to the mechanical parameters and conditions of the particular press brake. Futhermore, the press brake control system elements communicate according to a communication system having redundancy and error-checking features to be operable in hostile electrical and physical environments.
