The formability of sheet metal appears better in incremental forming than in conventional forming. In this study, the effect of process parameters-tool type, tool size, feed rate, friction at the interface between tool and sheet, plane-anisotropy of sheet-on the formability was investigated by experiments and FEM analyses. It was found that the formability is improved when a ball tool of a particular size is used with a small feed rate and a little friction. Due to the plane-anisotropy, the formability differs according to the direction of the tool movement. (C) 2002 Published by Elsevier Science B.V.
