Abstract: Industrial product development today is faced with the challenge of achieving shorter creation cycles to keep up with international competition. This causes constantly changing requirements for the geometry of the components and thus for the used forming tools. These tools must be designed much faster so that customer requirements are met quickly, which is feasible through a parametric CAD design. As part of a cooperative research project involving the GFaI and the IFUM, a fully parametric CAD model for a sheet-bulk metal forming process was developed. With this tool it is possible to produce cylindrical components with internal and external gearing by combined sheet and bulk forming operations. For this purpose, the CAD model of the tool system is divided into different assemblies. Each assembly consists of various components which relate to each other. Furthermore, the dependencies between the assemblies were built up parametrically via global constrains. An initial structure of the CAD model including constraints is described in this paper. In addition, various process limits are determined by means of experimental tests and calculations. In the first stage of the forming process, blanks are deep-drawn into cups. Due to the geometry of the gears, round cup forming tests were conducted to examine the drawing ratio for different materials (DC04, DP600 and HC260LA). The characteristic values are converted into parameter limits for the new CAD model. Thus, the forming tool can be designed depending on the material used and the required gear size, which can reduce the development time in the future.
