- Abstract
The technology of sheet-bulk metal forming (SBMF) offers the possibility of manufacturing metal parts from a flat semi-finished product with functional secondary forming elements. Therefore, this technology provides the advantages of a resource-efficient production by shortening the process chain, saving materials and reducing the production costs. However, high contact normal stresses arise in SBMF-processes, leading to increased tool wear. The project T06 deals with the further development of numerical wear calculation for processes with high contact normal stresses. The numerical wear modelling is performed using the adapted friction law according to Archard, based on the friction shear stress. This model is applied exemplarily for the wear calculation in an industry-oriented process based on an extrusion process of the company Fischerwerke GmbH. An experimental setup is developed which simulates the industrial application at laboratory level. A hydraulically working oscillating device is installed in this test stand. The influence of a superimposed oscillation on the process characteristics of the Fischer process is investigated. The focus is on a reduction of the average forming force and a related reduction of the tool loads.
