Nowadays Single Point Incremental Forming (SPIF) is really a new technology of forming metal sheet after its formation and long development in about five decades. Although it was invented in, 1967 by Leszak, an American inventor, but the applications innovative have just been popular from 1990 because advance controlling technology. This especially adapted to small batch, unique or single produ...

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...

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 This article outlines the development of an elastically foldable, bistable diaphragm geometry that enables increase in compression volume compressors compared to use flat diaphragms. Using a Finite Element Model (FEM) ABAQUS/Standard, several membrane geometries (truncated cone, and dome) were calculated analyzed with regard their elastic deformation. Selected produced using Single Poi...

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 this study, an artificial neural network was used to predict the minimum force required to single point incremental forming (SPIF) of thin sheets of Aluminium AA3003-O and calamine brass Cu67Zn33 alloy. Accordingly, the parameters for processing, i.e., step depth, the feed rate of the tool, spindle speed, wall angle, thickness of metal sheets and type of material were selected as input and t...

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...

In this study, single point incremental forming (SPIF) of Al-Li alloy sheets under different angles are studied via both experimental methods and numerical simulations. The effect angle on the geometric accuracy SPIFed component is studied. simulation results show that higher angle, lower stress at corner, leading to better geometrical accuracy, which also experimentally validated. It found hig...
