Abstract
Incremental sheet metal forming is a novel and quick process suitable for rapid prototyping and production of small batch of sheet metal components. The forming operation is carried out at room temperature employing a CNC machining center. A specially designed spherical tip tool and a simple support to hold the formed sheet are required to undertake the process. In this work, incremental sheet metal forming was carried out on 0.5 mm AA 1050 sheet to study the impact of process and product characteristics. The process parameters involved are rotation of the tool, feed in x, y directions and axial feed in z direction. Two process conditions are used, namely, with lubrication and without lubrication. Frustum of square pyramid has been considered as the shape of the component form the formed component strain distribution was measured. To measure strain distribution, circular grids were etched on the surface. Formability diagram were plotted with the results. The results of forming with lubrication and without lubrication were compared and brought out.
