Steel laser tailor-welded blanks (TWBs) are produced by end-to-end joining of base sheets using different welding methods. In this article, the formability of laser TWBs of St12 and St14 with thicknesses of 1 mm and 1.5 in single point incremental forming process were experimentally and numerically investigated. First, the forming limit wall angle was experimentally determined for each of the b...

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...

In recent years, numerous scientific and technological innovations have been introduced in the fields of medicine dentistry. The application computer-based engineering techniques has enabled significant improvement design performance biomedical components, including implants prostheses. Innovative flexible manufacturing methods, such as single point incremental forming (SPIF), allow cost-effect...

Single point incremental forming (SPIF) that will produce non-symmetric sheet metal parts has been rarely dealt with so far. SPIF of a Francis hydro-turbine vane made aluminum alloy is studied as typical example in this work. At first, concave geometry, encompassing the desired shape designed, from which formed part be ultimately cut out. The necessary toolpaths are created by using CAM softwar...

Abstract For heat-assisted single point incremental sheet forming (SPIF) works of Ti-6Al-4 V sheets, the use lubricant has shown significant effects on surface quality and geometric accuracy at higher temperatures. Molybdenum disulphide (MoS 2 ) is a common widely used in SPIF works, however, it usually indicates ineffective performance high This article studied different lubricants MoS propose...

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...

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...

Single Point Incremental Forming (SPIF) is a dieless and flexible forming technology that allows performing complex shapes presents high economic payoff for low production series. In this context, research an experimental investigation of Polyether ether ketone (PEEK) sheets deformed by SPIF at room temperature, determining the influence process parameters on material formability. The performed...

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...
