Investigation of part blank modelling accuracy in the progressive die stamping process
Santrauka
This article deals with the possibilities of improving part blank modelling accuracy for the process of progressive die stamping based on experience obtained in an automotive die manufacturing company. An improvement suggestion for engineering efforts is proposed. To confirm the validity of the proposition, an experimental trial run of progressive stamping dies was performed, the results of which were compared with simulation results. It was established that the improved modelling method is about 30% more accurate in respect to trim line deviation.
