Patent ID: 8768503

Claim:
A method to establish a parametrized process model for a forming simulation of a tool for deep drawing of a sheet metal based on a predefined component geometry, said tool comprising a die, a binder and a punch, whereby the binder is used to fix the sheet metal in an edge zone of the die, before the sheet metal is pressed in a drawing direction by a means of the punch into the die, and at least one parametrized addendum which complements the component geometry along at least one component edge, said method comprising the following steps; a. providing the predefined component geometry; b. determining a direction of drawing; c. providing a binder surface; d. creating the geometry of at least one parametrized addendum by arranging sectional profiles along the at least one component edge; e. spacing the sectional profiles at a distance from one another, the sectional profiles having initial directions pointing away from the component edge, whereby said initial directions are determined by adapting the direction of the sectional profiles to a course of the component geometry and avoiding overlap of the sectional profiles; f. connecting the sectional profiles to create addendum surfaces.
