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 ...

Owing to the relatively lower dimensional accuracy and poorer surface finish compared other additive manufacturing (AM) technologies, directed energy deposition (DED) yields parts that often require extensive post-processing. Thus, it is well suited be combined with subtractive or deformation processes into hybrid strategies, which may enable microstructure engineering of near-net-shape directl...

With a view to reducing the springback and twist of PEEK during incremental forming process, ultrasonic vibration is introduced into polymer thermal single-point process (SPIF). In this study, effects temperature on formed parts are investigated. Several modified tool trajectories developed, influence trajectory also studied. Finally, microstructures analyzed by XRD. The results show that incre...

The use of biodegradable materials has a growing field application due to environmental concerns, however, scientific research on incremental forming using biomaterials is scarce. Thus, this study focuses the single point (SPIF) process applied composite sheet that combines thermoplastic matrix (Solanyl) reinforced with natural fibres (flax). influence parameters final geometry determined, eval...

Incremental sheet metal forming process has seen one of the highest increases in diversity last years. Single point incremental (SPIF) become more attractive due to multiple benefits it possesses over other conventional cold processes such as deep-drawing. However, yet arise large-scale industrial implementation because its drawbacks high production time and low accuracy, which lead prototype p...

This study investigates the deformation and fracture mechanisms of two testing methods, tension under cyclic bending (TCB) plus compression (TCBC) their relationship to single point (SPIF) double-sided (DSIF) incremental sheet forming processes. Experimental tests were carried out by using a bespoke TCBC test rig DSIF machine with grade 1 pure Ti samples. The results show elongation-to-fracture...

This paper presents a direct substructuring method to reduce the computing time of implicit simulations of single point incremental forming (SPIF). Substructuring is used to divide the finite element (FE) mesh into several non-overlapping parts. Based on the hypothesis that plastic deformation is localized, the substructures are categorized into two groups: the plastic—nonlinear—substructures a...

Single point incremental sheet metal forming has passed through a period of ample improvement with developing responsiveness from research societies and industries globally. The process expressively spared the practice using costly dies, which makes it an appropriate for manufacturing prototypes small batch production. It also discovers easiness in fabricating components timeworn equipment. Add...
