Abstract
Proceedings of the REAPS Technical Symposium. Paper No. 24: The Application of a CNC Frame Bender within an Automated Shipyard. The CNC frame bender is a machine being developed to utilize a computer controlled method for the cold forming of ship frames, especially large steel beams. The technology being incorporated will: (1) shape ship frames by applying mostly pure bending moment to the members - a four point bending action instead of the conventional three point bending; (2) use computer control with feedback to carry out the bending, including corrections for springback; (3) eliminate out-of-plane deformation by built- in computer routines that correct incipient errors detected during the bending; and (4) straighten beams in both horizontal and vertical planes. The frame bender will handle beams with either symmetrical or asymmetrical cross sections.
