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...

Sheet metal channels with variable sections or local features have been widely used in automobile and construction industries, novel forming techniques, such as flexible roll process, flexibly reconfigurable Deakin’s facility, chain-die recently developed to manufacture those channels. In this paper, the feasibility of technique is systematically investigated through experiment finite element s...

In this paper, an analytical method based on Modified Slab Method of analysis is presented to study the asymmetrical rolling process due to difference in work rolls radii, rolls speeds and interface frictions. The shear force imposed on material along the contact region is considered to be a function of the frictional factor and the roll gap geometry. Elastic-plastic with linear work hardening ...

Double-roll rotary forging is an emerging plastic forming technology based on forging. Owing to the advantages of labor saving, small eccentric load, low noise and vibration, good uniformity, high surface quality, material it very promising for fabrication large-diameter thin-walled disc. To date, a few relevant researches double-roll metal discs have been reported, mechanisms process disc work...

Cold rolling process is a complicated process which can be optimized by changing in variables and settings. This paper presents a set-up optimization system developed to calculate reductions and inter-stand tensions for each stand of a five stand tandem cold mill. The main objective in this optimization is minimization of power consumption. First, by using the analytical method, the equations ...

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...
