Abstract
The single-point incremental forming (SPIF) process is described. The maximum draw angle for SPIF is defined and specific values are given for 3003-0 and 5754-0 aluminium. Forming limit diagrams (FLDs) are developed for incremental forming of aluminium sheet, using SPIF. Five distinct shapes are used to define the forming limits: a hemisphere, a straight-sided cone, a hyperbolic-sided cone, a pyramid, and a shape with five lobes. Strains of more than 300 per cent have been achieved for all shapes.Keywords
