Abstract	The modified fine blanking technique is the subject of this research, along with a comparison of conventional blanking and shaving. The modified process does not require the use of a triple-action press and the press can be run at the same rate as conventional blanking. A counter-pressure punch and assembly are used to prevent the fracturing of the cut, which is similar to standard fine blanking. The difference between the two fine blanking techniques is that the modified method does not hold the material from lateral movement during the perforating operation. Furthermore, to achieve an optimum comparison of all three methods (conventional blanking, shaving, and modified fine blanking), a die set was designed that could produce parts for each of these processes. The evaluation of each method was done by cutting similar samples of each method and placing them in plastic, which allowed microscopic comparisons to be made of the three methods. A trade-off analysis of the various methods demonstrated that the modified fine blanking technique is superior to the other techniques.
