Abstract:
1. A shell plating developing method for developing a shell plating of a predetermined shape on a flat plate, comprising the steps of: determining a first connection line and a second connection line constituting a shell plating lattice system based on a curvature of said shell plating and being orthogonal at each lattice point of said shell plating lattice system; and developing said first connection line as a straight line on the flat plate while maintaining the length of the first connection line, and developing said second connection line on a flat plate as a line constituting a flat plate lattice system along with said straight line and being orthogonal to said straight line at each lattice point of the flat plate lattice system in such a way that the integrated value of the amount of machining corresponding to the expansion ratio or the shrinkage ratio of the second connection line is minimum.
