Ultrasonic vibration assisted single point incremental forming (UVaSPIF) is based on localized plastic deformation in a sheet metal blank. It consists to deform gradually and locally the sheet metal using vibrating hemispherical-head tool controlled by a CNC milling machine. The ultrasonic excitation of forming tool reduces the vertical component of forming force. In addition, application of ul...

Incremental sheet forming (ISF) process show a great potential in the manufacturing of small series production or prototype development parts. One metal process, where contact between punch and is single point, known as point incremental (SPIF). The part manufacture with simple tool, punch, that performs combined movements on vertically horizontally directions. paper introduces study regarding ...

In recent years, in order to reducing die design and manufacturing costs, Multi point forming technique has gained an increasing interest because of its high flexibility. In this process, the conventional fixed shape solid die sets are replaced with a pair of opposite matrices of controllable elements. In this paper, the fundamental principles of multi-point forming was described and the possib...

Pressure-assisted single-point incremental forming (PA-SPIF) is one of the emerging techniques for sheet metals that have been subject rigorous research over past two decades. Understanding its mechanisms and capabilities growing as a result. Open gaps are still present in material constitutive modelling accurate numerical predictions finite-element simulations characteristics localised deforma...

Abstract Putting in place circular economy strategies is an urgent challenge to face. In this scenario, manufacturing processes play a relevant role as efficient material reuse enabler. Scientists have make effort either find new process or rethink old reprocess end-of-life (EoL) component recover both and functions. paper, single point incremental forming (SPIF) used for reshaping sheet metal ...
