Adjusting residual stresses by flexible stress superposition in incremental sheet metal forming
نویسندگان
چکیده
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, causes beneficial tool side compared tensile induced by single-point process without such supporting die.

Prediction of Instability in Planar Anisotropic Sheet Metal Forming Processes
In this paper instability of planar anisotropic sheet metal during a few forming processes is investigated for the first time. For this reason components of the constitutive tangent tensor for planar anisotropic sheets are developed. By using the above tensor location of necking is predicted. Direction of the shear band is also predicted using the acoustic tensor. A finite element program is pr...

One of the methods for making prototypes is incremental forming process. In this method, the forming tool, performs a pre-programmed movement by the CNC machine and runs the desired path. This modernization process is used in the automotive, aerospace, military, medical and other industries. One of the most influential parameters in this process is forming tool. This parameter is effective in f...
متن کاملLaser-assisted asymmetric incremental sheet forming of titanium sheet metal parts
Asymmetric Incremental Sheet Forming (AISF) is a relatively new manufacturing process. In AISF, a CNC driven forming tool imposes a localized plastic deformation as it moves along the contour of the desired part. Thus, the final shape is obtained by a sequence of localized plastic deformations. AISF is suitable for small series production of sheet metal parts as needed in aeronautical and medic...
متن کاملExergy analysis of incremental sheet forming
Research in the last 15 years has led to die-less incremental forming processes that are close to realization in an industrial setup. Whereas many studies have been carried out with the intention of investigating technical abilities and economic consequences, the ecological impact of incremental sheet forming (ISF) has not been studied so far. Using the concept of exergy analysis, two ISF techn...
