In this study, the effects of sheet thickness and the punch-die clearance for blanking CuZn30 sheet material has been investigated experimentally, and estimations through fuzzy logic have been developed for those parameters affecting product quality. 1 mm and 2 mm thick CuZn30 sheet materials were used in the experiments. Blanking experiments were carried out by manufacturing a modular die that had six different clearance values (0.08 mm, 0.10 mm, 0.12 mm, 0.14 mm, 0.16 mm, and 0.18 mm). Blanking forces were determined using a load cell during the experiments. Consequently, in blanking operations, burr height increases with increasing clearance while blanking force and the smooth shear fracture rate decrease with increasing clearance.
