Interactions of process variations and nominal tool design on clinched joints

Approach for meta-model-based variation simulation for different tool designs
Approach for meta-model-based variation simulation for different tool designs

The virtual design of clinch joints is usually based on the assumption of ideal boundary conditions that do not fully reflect reality. As a result, a reliable realistic prediction of the clinch joint properties has not yet been possible. The latest KTmfk publication therefore presents a meta-model-based method that enables the quick prediction of clinch joint properties, taking into account unavoidably scattering process parameters and the nominal clinch tool design. This shows that the tool already has a considerable influence on the scattering of the clinch joint properties under consideration of realistic boundary conditions. Therefore, a simultaneous tool design and variation analysis is recommended to ensure quality.
