A Numerical Approach to the Establishment of a Sheet Metal Forming Process Technology

A numerical approach to the establishment of a sheet metal forming process technology based on process forming energy evaluation, optimized modeling as relates to CNC programming and the definition of forming technology has been presented in this paper. The sheet metal forming energy evaluation, by means of finite element method, has been used to assess the dependency of the energy consumption on the variation of parts shapes before the elaboration of their developed shape prior to their machine production. The modeling approach is used for creating a model with the ultimate purpose of making a developed shape of sheet workpiece in order to make a CAD format for transfer to software for production. DC 01 (EN 10130 –Cold Rolled Steel Sheet and Strip for Cold Forming) was used as the production material and different parts for sheet metal forming have been chosen. Sheet metal forming technologies (punching, nibbling, marking, embossing, beading, tapping, extruding, punch marking and bending) for production due to their material savings, and increasingly reduced processing time are taken in the account in these investigations
