Abstract

An automated flexible manufacturing system for fabricating electrical cable harness assemblies. The system includes a wire preparation system in which the wires are cut to length, provided with the desired electrical terminations and marked for identification under the control of computing means to which wire harness data is fed. The prepared wires are transported to an automated cable harness assembly system which is also controlled from computing means to which the wire harness data is fed.
