The incremental sheet metal forming (ISMF) process is a new and flexible method that is well suited for small batch production or prototyping. This paper studies the use of the finite element method in the incremental forming process of AA1050 sheets to investigate the influence of tool diameter, vertical step size, and friction coefficient on forming force, spring-back, and thickness distribut...

There are several parameters that have significant influence in metal forming process. One of the most important of them is friction coefficient. Friction can change the pattern of metal flow and the force needed for deformation. It is necessary to determine the friction coefficient to study the effect of friction on metal forming process. This study is concerned with numerical and experimental...

Friction has an important influence in metal forming operations as it contributes to the success or failure of the process. In the present investigation, the effect of friction on metal forming was studied by conducting compression tests of cylindrical Al-Mg alloy using Finite Element Method (FEM) technique. Three kinds of compression tests were performed. For the first test, a constant coeffic...
