Abstract
In the booming market of electrified mobility, product cost plays a crucial role for the competitiveness of electric vehicles. Approximately 70% of the product costs are determined in the product development phase [1]. Therefore, an early cost evaluation is necessary to check the achievement of cost target and if needed to modify the design as early as possible. To get a holistic view, as one part of the manufacturing cost for lamination stacks, the stamping tooling cost should to be taken into consideration. This work investigates the cost of progressive die in the lamination stack production. By following design of the lamination and the production scenarios selected for stamping, the tooling cost can be estimated based on the dimension and complexity of the stamping part. Besides design parameters, the production scenario also influences the tooling design and its cost. The area of the stroke station is very different while applying segmenting technology for stator stamping process compared with stamping the stator ring. The proposed model also presented an approach to evaluate the complexity of the stamping part design, which is crucial for determining the number of progressive die stations.
