Abstract To relate the thermomechanical behaviour and microstructural evolution of heat-assisted incremental sheet forming (SPIF) for Ti–6Al–4 V sheet, multi-scale models based on crystal plasticity finite element model (CPFEM), representative elementary volume (RVE), cellular automaton (CA) were established in this article. An experimental-scale CPFEM was built advance to provide macrograin le...

With a view to improving the surface quality of magnesium (Mg) alloy at warm temperature, ultrasonic-assisted single-point incremental forming (SPIF) is proposed. The Mg during SPIF primarily affected by two parts: orange peel patterns non-contact and scratches adhesive wear contact surface. In this work, AZ31B sheet parts different temperatures ultrasonic amplitudes evaluated examining roughne...

In Incremental sheet metal forming process, one important step is to produce tool path, an accurate path of the main challenge incremental process. Various factors should be considered prior generation i.e. mechanical properties metal, holding mechanism, speed, feed rate and size. this work investigation studies have been carried out find different strategies control twist effect in final produ...

Single point incremental forming (SPIF) process has proven benefits in terms of formability, flexibility, and low cost as compared to conventional sheet forming, although it some issues such dimensional accuracy quality surface finish for materials. The SPIF is considered a potential method producing customised medical parts craniofacial implants using titanium sheet. This investigation aims an...
