Process Driven Automated Rebar Bending

This paper will present a new concept for rebar bending, which is based on merging the advantages provided by integrating electronic sensors, computer controlled motors, and data communication with a personal computer. The complexity of predicting the springback of rebar through pattern recognition and impedance control is also being discussed. It is shown how such a system could reduce costs associated with trucking, handling, site storage and wasted time due to short shipments, late deliveries, change orders, and inappropriate batching of the reinforcement bars.
