METHOD AND DEVICE FOR INFLUENCING THE SHEARED AND FUNCTIONAL EDGE AT FINE BLANKED FINISHED PARTS

摘要

PURPOSE: A method and device for improving the cut functional edge of fine blanked finishing element are provided to maintain a functional surface and to improve edge roll over. CONSTITUTION: A method for improving the cut functional edge of fine blanked finishing element comprises the next step. The topography of a desired roll over(4) is determined at a finishing part and topography of the expected roll over. A readjusted contour is determined by applying material tolerance in order to compensate insufficient volume. The topography of the roll over, in which the new virtual fine blanking about the readjusted contour operates, is determined.
