Work package contribution

Work package 1: Characterization of the fine-blanking process.

In this part the work conditions and specifications for fine blanking different materials will be collected. The results will be used for the next WP’s.

Work package 2: Optimization of the tool material.

As explained above the material selection and the subsequent heat/cold treatment of these materials is of upmost importance for the success of the final coating operation. In this part several tool materials used in industrial environment will be listed from WP1 and a well defined selection will be made for the best coating development in WP 3. Also new developed steel materials will be involved in this selection. The selected materials will be subjected to a combined heat and cold treatment to enhance hardness, toughness and stability. Finally characterization of the mechanical and structural properties will be performed. In combination the coating development and the well defined selection of steel materials will be made for the laboratory tests. From the results obtained in WP3 and WP4 feedback will be given to optimize the substrate by adapting the heat or cold treatment.

Work package 3: Coating development for fine blanking tools.

The coating development starts with the coating of reference samples and the determination of the coating properties on it. In iterative loops the coating properties shall be optimized. In the next step test and production tools will be coated with the best coating procedures. After cutting tests in WP 4 and WP 5 a detailed wear analysis will give information for further coating optimization.

Work package 4: Cutting tests on a laboratory scale

The cutting test on laboratory scale will be done on a fine blanking tool already available at Fraunhofer IWU where several test geometries exist. One test geometry will be chosen, that allows the determination of tool wear and component quality under relatively short production cycles. The test will be done in a conventional press at Fraunhofer IWU. As results the tool analysis and the component quality measurements will be delivered to all project partners for a detailed evaluation of the best coating and tool material combinations for the fine blanking application.

Work package 5: Cutting tests under production conditions

To verify the practical tests on a laboratory scale, the coated tool and active parts for a demonstrator will be used at a supporting SME in each country for application trials under production conditions. Therefore the demonstrator tool will be manufactured, heat treated and coated. After the tests the tool analysis and the component quality measurements will be delivered to all project partners.

Work package 6: Evaluation and systematization of the experimental results, final report

The results of the above mentioned cutting tests in WP4 and WP 5 will be compared and evaluated in order to determine the performance of the examined combination of substrate and coating for fine blanking. In the end the final report will be written by all partners.

Work package 7: Transfer of the results to the industry.

This part will provide professional feed-back between the partners and users as well as the dissemination of the results within the user group.
