Abstract: An experimental validation was established to evaluate the cutting edge by Burr Free Technology (BFT) implemented on the blanking tool design. The output of the BFT is presented in this paper with the optimized tool design factors. The combination of the conventional positive tool-die clearance and the negative tool-die clearance was introduced in this BFT tool design to derive the predicted experimental results. The sequences of the entire BFT concept was introduced in this paper. The BFT tool design with lower punch protrusion of 0.700mm and the combination of the positive punch-die clearance for upper punch and lower die and the negative punch-die clearance for lower punch and upper die respectively concluded the most optimized results.
