MATHEMATICAL SHIP LOFTING AND NUMERICAL CONTROL OF SHIPYARD FABRICATING EQUIPMENT. VOLUME 6, NUMERICALLY CONTROLLED SHIPYARD FABRICATING EQUIPMENT, SUMMARY REPORT

A description is given of the conventional methods of lofting and fabricating ship parts and concepts are presented for replacing these methods with mathematical lofting and numerically controlled or automatic processes. Presented are: (1) specifications for numerically controlled flame and plasma-arc cutting machines; (2) design concepts and specifications for stretchforming machines; (3) design concepts and specifications for a machine for cutting shell plate after forming; and (4) procedure for making a cost analysis of the proposed process. Recommendations are made for continuing development of the new concepts presented toward the goal of reducing ship construction costs. (Author)
