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...

Tailor-made blanks are sheet metal assemblies with different thicknesses and/or materials and/or surface coatings. A monolithic sheet can be machined to make the required thickness variations that is referred as tailor machined blanks. Due to the thickness variation in tailor machined blanks, laser bending of these blanks is more complicated than monolithic plates. In this article, laser formin...

Incremental sheet forming (ISF) is an emerging technology that has shown great potential in customized three-dimensional (3D) parts without the use of product-specific dies. The force reduced ISF due to localized nature deformation and successive forming. Forming plays important role modeling process accurately, so it needs be evaluated accurately. Some attempts have been made earlier calculate...

The most prominent feature of sheet material forming process is an elastic recovery phenomenon during unloading which leads to springback and side wall curl. Therefore evaluation of springback and side wall curl is mandatory for production of precise products. In this paper, the effects of some parameters such as friction coefficient, sheet thickness, yield strength of sheet and blank-holder fo...

This paper describes single point micro incremental forming (SPMIF) applied to the fabrication of meso-scale shell structures. The authors have developed SPMIF without using any die and backing plate for flexible micro forming of miniature 3D products in a range of micro meters to sub-millimeters. A desk-top type of CNC milling machine was constructed as an experimental apparatus. Thin aluminum...
