An overview of stabilizing deformation mechanisms in incremental sheet forming
In Incremental Sheet Forming (ISF) strains can be obtained well above the Forming Limit Curve (FLC) that is applicable to common sheet forming operations like deep drawing and stretching. This paper presents an overview of mechanisms that have been suggested to explain the enhanced formability. The difference between fracture limit and necking limit in sheet metal forming is discussed. The neck...
متن کاملAn Overview on Incremental Sheet Forming, a Method for Rapid Manufacturing of Hollow Metal Parts
During the last decade, incremental forming is an innovative processing method which has been strongly investigated. Its potential as a flexible manufacturing method was noticed. This paper aims to present a comparative study of the recent worldwide developments in the field of incremental sheet forming (ISF), as a flexible method for manufacturing hollow metal parts. There are pointed out its ...
متن کاملPrediction of Instability in Planar Anisotropic Sheet Metal Forming Processes
In this paper instability of planar anisotropic sheet metal during a few forming processes is investigated for the first time. For this reason components of the constitutive tangent tensor for planar anisotropic sheets are developed. By using the above tensor location of necking is predicted. Direction of the shear band is also predicted using the acoustic tensor. A finite element program is pr...
متن کاملExergy analysis of incremental sheet forming
Research in the last 15 years has led to die-less incremental forming processes that are close to realization in an industrial setup. Whereas many studies have been carried out with the intention of investigating technical abilities and economic consequences, the ecological impact of incremental sheet forming (ISF) has not been studied so far. Using the concept of exergy analysis, two ISF techn...
متن کاملThe mechanics of incremental sheet forming
The deformation mechanism of incremental sheet forming (ISF) is examined experimentally through forming specially prepared copper sheets. Strain distributions through the thickness of the sheets are measured for two configurations of ISF: two-point incremental forming (TPIF) and single-point incremental forming (SPIF), and a comparison is made to pressing. The measurements show that the deforma...
