Influence of Process Parameters on the Deep Drawing of an Axisymmetric Workpiece

Optimization of process parameters in sheet metal forming is an important task to reduce manufacturing cost. To determine the optimum values of the process parameters, it is essential to find their influence on the deformation behavior of the sheet metal. Punch radius, matrix radius and blank holder force are considered as process parameters. In finding optimum values, advantages of finite element software ABAQUS, statistical design of experiments(Taguchi method) are exploited. Finite element analyses are conducted for combination of process parameters designed using taguchi experimental design. Optimum results obtained from analysis of variance (ANOVA) in experimental design. The analysis results presented herein are further validated by comparing them with experimental results.
