Abstract
On the basis of experimentally determined lateral spread data a program for computer aided roll pass design was developed. The experimental data are expressed in terms of area ratios vs width-to-thickness ratio for different material properties. A maximum allowable deformation is put in by the designer and the program iterates until the calculation and experimentally determined value of the lateral spread coincide. Flash and neutral line are interactively selected. Center of gravity, initial cross sectional area (rectangular), and roll pass schedule are calculated. The results for a roll pass schedule are compared successfully with experiments. The program has been applied for different profile types (airfoil shapes, flat, and complex profiles) and compared with manually designed airfoil shapes.
