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...

Abstract Process-induced residual stresses significantly influence the mechanical properties of a formed component. A polymer pad is used as flexible die in two-point incremental forming to induce compressive component during process. Experimental and numerical results illustrate stress superposition on properties. It shown that active support, using geometry-independent polyurethane die, cause...

recently, incremental sheet metal forming (ismf) process as one of the new methods in rapid prototyping collection has been considered by researchers. this process is based on a defined path in cnc controller and applies a spherical-head tool that supplies the required pressure for sheet metal forming. despite affirmation of process ability in forming symmetric geometries, some of its aspects s...

Incremental sheet forming (ISF) technology is a suitable and flexible solution to create complex 3D geometries of the sheet. A gradually formed into desired shape with tool usually attached CNC machine or robot. This process valid metal as well polymer sheets. However, inaccuracy geometry occurring errors in previously discussed industries prove novelty technology.
 In this research novel ...

Uniform wall thickness plays an essential role in avoiding forming failure incremental sheet forming. However, it is challenging to promote the uniform distribution of single-pass high angle and complex three-dimensional thin-walled parts using flexible dieless technology. In this article, based on hydraulic support single-point technology, finite element software used simulate analyze influenc...

New manufacturing technologies are developed fast in order to keep up with the market demands, both in the field of metal cutting and metal forming. The Asymmetric single point incremental forming (ASPIF) is a manufacturing technology with a high degree of novelty, which allows the user to manufacture complex parts by metal forming, using only a punch and an active plate without the need of usi...

The present paper aims to study the behavior of tailor welded blanks subjected a single point incremental forming (SPIF) process from an experimental view. This was chosen deform truncated cone shapes AA1050 aluminum alloy with different thicknesses. A uniaxial tensile test performed determine mechanical characteristics alloy. Initial tests implicated use variable wall angle parts which were pr...
