Dieless Sheet Metal Forming

This paper aims to develop a similiar method that can form flat metal sheets into three dimensional shapes without using dedicated dies.

Kim tj yang dy 2000 improvement of formability for the incremental sheet metal forming process. Abstract roboforming is a dieless incremental robot based sheet metal forming process for cost effective manufacture of prototype parts and small batch sizes. Incremental sheet metal forming process by amino called dieless nc forming. Scientific output incremental sheet forming isf is a dieless sheet metal forming technique.

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. For this purpose very simple and compact tooling is devised and put on the bed of a numerically controlled nc machine tool. Metal forming incremental forming dieless forming. Dieless nc forming or incremental sheet forming is a process that can produce complex shapes from various materials.

Thibaud s hmida rb richard f malécot p 2012 a fully parametric toolbox for the simulation of single point incremental sheet forming. Flexible dieless forming spinning designers of sheet metal components are increasingly looking for flexible and materially efficient manufacturing techniques especially in the automotive industry.

In isf a forming tool mounted on a cnc milling centre follows the predefined incremental tool path and deforms the sheet which is clamped at its outer periphery. This process is based on localized plastic deformation in a sheet metal blank. 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. Science makes complex jobs simple.

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. The key advantage of isf over conventional sheet forming processes is that specialised dies are not required. 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.
