Abstract
The application of hard coatings to metal forming tools is essential in order to obtain lower interfacial friction coefficient and extended tool life. By considering friction and wear as interactive responses from a coating tribo-system, an interactive friction model developed recently has enabled the prediction of the friction coefficient evolution and the coating breakdown. In the present research, the interactive friction model was implemented in the FE simulation of a sheet metal forming process, via a multi-objective cloud FEA system. The wear distribution on the punch, die and blank holder has been visualised, which has shown that wear is strongly dependent on the forming parameters, such as blank holding force. Based on these simulation results, predictions can be made for the remaining coating thicknesses. Moreover, preliminary guidelines are presented on the coating design to enable an optimised coating thickness distribution.
