Abstract: With the current situation of the global sheet metal industry, meeting market demand for low-cost, high-quality sheet metal products is a major problem. Sheet metal blanking is a metal production method that is widely used in automobiles, aircraft, electrical and electronics equipment, heavy machinery, and other industrial equipment. Burrs are undesirable material and ragged edges raised on the surface of the blank during the blanking process. The creation of a burr on a piece of metal reduces its quality, accuracy, and utility. As a result, it must be separated by further processing such as machining or deburring, which raises the cost per item in manufacturing. Burr can be reduced by selecting the right collection of process variables. This paper provides a review of finite element simulations of the blanking process using the Ansys/Explicit Dynamics software package with various sets of process parameters. It also examines the author's design of experiments (DOE) methodology and the effects of process parameters on burr formation and equivalent stress.
