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...

Two-point incremental forming method is considered a modern technique for manufacturing shell parts. The presence of bottom punch during the process makes this technique far more complex than its conventional counterpart i.e. single-point incremental forming method. Thus, the numerical simulation of this method is an essential task, which leads to the reduction of trial/error costs, predicts th...

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...

New methods in metal forming are rapidly developing and several processes used to optimize manufacturing components reduce cost production. Single Point Incremental Forming (SPIF) is a sheet process for rapid prototyping applications small batch This work dedicated the investigation of profile geometry thickness evolution truncated pyramid. The influence parameters during SPIF also studied. A n...

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...

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...

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....

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 The single point incremental forming (SPIF) process is a flexible and progressive manufacturing technique in the monolithic molding domain of heterogeneous metal pressing panels, which can contribute to panels with complex contour applicable fabrication small amount titanium mesh plates for cranial prosthesis. A sandwich construction was proposed this paper purpose inhibiting indentati...
