| Abstract Scope |
Incremental sheet forming is a rapid-prototyping process designed for manufacturing sheet metal products. Despite its high flexibility and efficiency in manufacturing low-batch products, the geometric inaccuracy of formed parts, such as the so-called “pillow effect” is considered to be a major drawback of ISF. This study aims to assess the development of the pillow effect in two different ISF methods, Double-Sided Incremental Forming (DSIF) and Two-Point Incremental Forming (TPIF), to provide insight into the developing stages of the pillow effect. A set of experimental evidence is provided to show how pillows are formed throughout the two different ISF methods. Finite element models are also introduced to provide quantitative conclusions, followed by a discussion on what affects material flow in each process due to differing material-supporting schemes. |
