THE CASE WESTERN RESERVE N/C FRAME BENDING MACHINE

A ship-frame bending machine which can operate under self-adaptive computer control is described. Advantages of this automated cold-forming system compared with conventional cold-forming and hot-slab bending process include: (1) complete elimination of lofting or templating; (2) direct compatibility with data generated by the AUTOKON computer program package for ship design; (3) reduced construction costs and time; (4) replacement of a costly labour-intensive activity with a more efficient capital-intensive process; (5) reduction of assembly costs because of the capability to produce more precise frames by minimising deformation, buckling and twisting. The primary emphasis of the paper is on the NOVA II computer control algorithm used to accomplish the bending.
