Titel:: Interaction of heat generation and material behaviour in sheet metal blanking
Abstract:: A temperature rise occurs in the sheet metal and tool parts due to the dissipation of a large part of plastic work during blanking. The resulting temperature in the shearing zone has various impacts on the process. The correlation between the temperature rise and sheet metal behaviour under varying process parameters is investigated. Causal associations can be shown by in-situ measurements of the dynamic temperature development at the cutting edge of the punch and analyses of the sheet metal behaviour. The presented results provide essential knowledge for further experimental, analytical and numerical blanking investigations. © 2015 CIRP. «
