Development of a Software Module for the Evaluation of Tool Life in Cold Forging

Project Status: finished


The application of the finite element method offers considerable opportunities in the development of high loaded tool systems for bulk metal forming processes. In addition to the analysis of material flow and tool load, the prediction of tool life and probable failure cause gains in importance. Therefore, cold forging tools from industry are analysed by calculating of the process dependent load and by evaluating of the real tool life data and its statistical characteristics. The calculated tool load and the tool life data form the knowledge basis for a software module for the lifetime prediction that can extend commercial FEM codes. The correlation between the tool load, which can be described by damage parameters, and the expected tool lifetime is performed by the application of an artificial neural network.
