Abstract
AbstractIn this paper an optimization of the dynamic blanking process with using E‐PLANNER, ANSYS and MATLAB programmes was presented. The main aim of this work was to obtain the high quality of the cut surface in function of: the size of clearance between punch and die, value of fillet radius of the punch edge and the speed of blanking. Numerical analyses were conducted in Ansys LS‐Dyna programme, with use of the explicit method and the experiment plan had been done before. Five levels rotary plan, was used. Unknown coefficients in mathematical model in the shape of quadratic equation with interactions were obtained. Obtained regression function was optimized in MATLAB programme, and determined optimal conditions of the process parameters. (© 2008 WILEY‐VCH Verlag GmbH & Co. KGaA, Weinheim)
