Dieless Sheet Metal Forming

For this purpose very simple and compact tooling is devised and put on the bed of a numerically controlled nc machine tool.

Dieless sheet metal forming. Advantages over conventional sheet metal forming because the process can be controlled entirely by cnc processes no die is required as is in traditional sheet metal forming. Kim tj yang dy 2000 improvement of formability for the incremental sheet metal forming process. Metal forming incremental forming dieless forming. Int j mech sci 42 1271 1286 crossref google scholar.

Science makes complex jobs simple. Flexible dieless forming spinning designers of sheet metal components are increasingly looking for flexible and materially efficient manufacturing techniques especially in the automotive industry. It was developed as an alternative manufacturing method for prototyping sheet metal stampings and producing panels in small lot sizes 1 to 500 pieces per month. Scientific output incremental sheet forming isf is a dieless sheet metal forming technique.

The flexible metal spinning process developed by our research group which requires no dies and achieves near net shape parts promises to deliver an alternative to currently employed stamping and drawing techniques. Incremental sheet forming isf is an umbrella term for a range of processes in which a sheet is formed incrementally by a progression of localised deformation. A wide range of shapes can be achieved by moving a spherical ended indenter over a custom designed. The elimination of the die in the manufacturing process reduces the cost per piece and increases turnaround time for low production runs because the need to manufacture a die is eliminated.

This process is based on localized plastic deformation in a sheet metal blank. Incremental sheet metal forming process by amino called dieless nc forming. Thibaud s hmida rb richard f malécot p 2012 a fully parametric toolbox for the simulation of single point incremental sheet forming. Its principle is based on flexible shaping by means of a freely programmable path synchronous movement of two industrial robots driving workpiece independent forming tools.

Abstract roboforming is a dieless incremental robot based sheet metal forming process for cost effective manufacture of prototype parts and small batch sizes. Scimplicity llc provides service software and machinery technologies for rapid low volume sheet metal forming based on the innovative dieless forming method for sheet metal components double sided incremental forming dsif developed by researchers and engineers associated with scimplicity and northwestern university. Dieless nc forming or incremental sheet forming is a process that can produce complex shapes from various materials.
