Fundamental Studies On The Incremental Sheet Metal Forming Technique

Incremental sheet forming or isf also known as single point forming is a sheet metal forming technique where a sheet is formed into the final workpiece by a series of small incremental deformations.

Fundamental studies on the incremental sheet metal forming technique.

Generally the sheet is formed by a round tipped tool typically 5 to 20mm in diameter. Fundamental studies on the incremental sheet metal forming technique. As recent market analysis studies have shown accuracy is one of the most important limiting factors for the deployment of spif in industrial applications. Also conventional techniques such as stretching and deep drawing processes were simulated by a commercial fem package for the purpose of comparison in the aspect of forming capabilities.

Firstly an optimal combination of tool and lubricant was explored to form the ta1 commercial titanium sheet metal parts. Fundamental investigations of the incremental sheet metal forming technique were performed in the present study. With this technique the forming limit curve flc appears in a different pattern revealing an enhanced formability compared to conventional forming techniques. In the present study the formability of an aluminum sheet under various.

Also conventional techniques such as stretching and deep drawing processes were simulated by a commercial fem package for the purpose of comparison in the aspect of form ing capabilities. Secondly the effect of the tool diameter on the surface texture of a part was investigated. Several aspects of incremental forming an innovative sheet metal forming process were studied. However studies have shown that it can be applied to polymer and composite sheets too.

Single point incremental forming spif is a sheet metal forming technique that is gradually evolving towards industrial applicability. With decreased design time and negligible production time incremental sheet forming provides reliability flexibility and quality while being an economical option in contrast to the traditional forming process. Incremental sheet forming is a flexible and versatile process with a promising future in the batch production and prototyping sectors.
