A Study on the Forming of Parts for Automobile using Fine Blanking Process

The fine blanking is a process of press-working which makes possible to produce thick sheet metal parts of finished sheared surface and close dimensional accuracy over whole material thickness in single blanking operation. Fineblanked parts in general are characterized by their cleanly sheared surface over the whole stock thickness and accurate size for the specific functions. The fine blanking technology is urgently needed to remove secondary operations which are necessary in conventional blanking operation and cost reduction. In this study, the effect of material texture and vee-ring on parts for automobile is investigated by experimental observation and analysis.
