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...

BACKGROUND Endogenous PIF, upon which embryo development is dependent, is secreted only by viable mammalian embryos, and absent in non-viable ones. Synthetic PIF (sPIF) administration promotes singly cultured embryos development and protects against their demise caused by embryo-toxic serum. To identify and characterize critical sPIF-embryo protein interactions novel biochemical and bio-analyti...

Abstract Incremental Sheet Forming (ISF) has attracted attention due to its flexibility as far forming process and complexity in the deformation mode are concerned. Single Point (SPIF) is one of major types ISF, which also constitutes simplest type ISF. If sufficient quality accuracy without defects desired, for production an ISF component, optimal parameters should be selected. In order do tha...

Knowing the importance of predicting acting forces during formation process, our research has conducted 27 Single Point Incremental Forming (SPIF) experiments in hyperboloid format, followed by Finite Element Method (FEM) simulations and regression equations were determined to estimate maximum axial force process. ANOVA analysis variance was used determine significance material parameters respo...

Spore coat protein synthesis in submerged pseudoplasmodia of Dictyostelium discoideum is dependent on the presence of a low relative molecular mass extracellular factor, SPIF, the activity of which can be mimicked by methionine. In vitro translation and northern blot analysis revealed that the level of spore coat protein mRNA in pseudoplasmodia incubated in the absence of methionine is little d...

This paper proposes an Intelligent Process Model (IPM), founded on the concept of data mining, for predicting springback in the context of sheet metal forming, in particular, Single Point Incremental Forming (SPIF). A limitation with the SPIF process is that the application of the process results in geometric deviations, which means that the resulting shape is not necessarily the desired shape....

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...

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...

Abstract The mechanical properties and the operating life of a formed component are highly dependent on residual stress state. There is always high magnitude stresses in components by incremental sheet forming (ISF) due to localized deformation mechanism. Hence, thorough understanding generation ISF necessary. This study investigates mechanism for two process variants ISF, i.e., Single Point In...
