【 摘 要 】

Sheet metal blanking is an industrial process widely used in automotive, electronics, aerospace and several other industrial applications. Burrs are the hard and sharp-raised edges formed at the cut edge of the blank during blanking process. Presence of a burr reduces the quality, accuracy and usability of the blank. So, it has to be removed by further processing like machining or deburring, which further increases the cost of production. Choosing proper process and geometric parameters can reduce the extent of burr. In this paper, finite element simulations of the blanking process for AA6082-T6 were carried out using the ABAQUS-CAE software package with various process and geometric parameters. Design of experiments (DoE) methodology was applied to understand the effects of the process and geometric parameters on the burr formation during blanking of metal sheets. This effort will not only help to optimize the blanking process, but also to increase the product quality and reduce the cost of production. Typical pattern of shear strain field evolved at various punch penetrations of sheet metal blanking is being studied.
