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 کاملThe Effects of Forming Parameters on the Single Point Incremental Forming of 1050 Aluminum Alloy Sheet
The single point incremental forming (SPIF) is one of the dieless forming processes which is widely used in the sheet metal forming. The correct selection of the SPIF parameters influences the formability and quality of the product. In the present study, the Gurson-Tvergaard Needleman (GTN) damage model was used for the fracture prediction in the numerical simulation of the SPIF process of alum...
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 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...
