Incremental Sheet Metal Forming Simulation

Hence with these methods it is possible to optimize the tool as well as the component.

Incremental sheet metal forming simulation.

13 3 3 incremental forming analysis. Simulation makes it possible to detect errors and problems such as wrinkles or splits in parts on the computer at an early stage in forming. In metal forming simulation the forming of sheet metal is simulated on the computer with the help of special software. Two broad divisions in the application of finite element analysis method for sheet metal forming can be identified as inverse one step and incremental.

Incremental sheet forming isf process is an advanced flexible manufacturing process to produce complex 3d products. Simulation of single point incremental forming spif in catia v5. In conventional forming process the products are produced by dedicated tools i e. In incremental simulations the forming process is divided into steps or increments and the problem is solved incrementally through time.

However isf does not require any dedicated tool. Incremental simulations yield all the relevant parameters that interest the forming expert from strain distribution sheet thickness and cracks for example to springback in the trimmed part stress distribution and hardening. The dimple was drawn and through our simulation we were able to successfully reduce the process to six steps in order to minimize the thinning percentage to the required level. It is important to understand the difference between the two calculation methods and to understand when it is appropriate to use each method.

The term incremental and one step refers to the calculation method used to solve the forming simulation mathematics of a sheet metal forming simulation problem. The forming process simulations were successful in eliminating forming problems splits wrinkles and other negative outcomes before the tooling was designed and manufactured. One step a single step calculation that completes very quickly in one step. In the present paper deformation behavior of sheet metal in an incremental forming process is numerically simulated using a dynamic explicit finite element code dyna3d halliquist 1989.

Within each step or increment the positions velocities accelerations and forces are calculated at the nodal points in the blank. Unlike one step simulation in which only the final part shape is solved incremental forming simulation allows the accurate modeling of sheet forming processes.
