Prediction of forces in incremental sheet forming using finite element method

Incremental sheet forming is one of the promising forming process, where sheet metal parts are directly produced from CAD drawing by using three axis CNC milling machine or dedicated machine. The aim of this article is to study the effectiveness of finite element analysis in predicting forming forces in single point incremental process. Tool diameter was varied and simulated results in terms of forming force in axial direction, X-direction and Y-direction were determined. The obtained results compared with analytical results and are in good agreement, shows capability of finite element analysis in predicting forming forces in incremental sheet forming process.

Experimental Study Regarding PA and PE Sheets on Single Point Incremental Forming Process

The present paper aims to present an experimental study on the behaviour of PA and PE sheets during the single point incremental forming. Due to the fact that the purpose of this research is to study the behaviour of PA and PE sheets during the single point incremental process both in terms of process forces and in terms of major and minor strain and thickness reduction, a Kuka Kr210 robot was chosen as an alternative to using a universal milling machine. The specimens were made of 3 mm PA and PE sheets. The size of the sheets was 250 mm x 250 mm. The forces measured on the three directions of the coordinate axes were compared. To measure the major strain, minor strain and thickness reduction, the digital image correlation method was applied.
