The forming parameters for incremental forming of aluminium alloy 3003 sheet are presented. Using two shapes for testing (a conical shape and a pyramid shape) and forming the sheet to various draft angles, the following data have been assembled: tensile tests, strain measurements, strength coefficient K and strain-hardening exponent n. The method of analysis of stress-strain diagrams used by Ford in the plane strain compression test are shown to be applicable. Relationships such as the sine law for spinning have been applied to the data and are presented.
