“…Wang et al [18] conducted experiments on rock cutting and metal cutting, and the results veri ed the possibility of cutting by cavitating water jet mixed with abrasives under submerged conditions. Yu et al [19] used the cavitation jet as the loading source, and abserved micro array expansion on copper foil with a thickness of 100µm. Their method is feasible for the exible expansion of metal foil, eco-friendly, low cost, easy control and mass production.…”

This study proposes a new technology of exible micro blanking with cavitation jet to improve the quality of micro blanking parts. We simulated the cavitation jet, obtained the change of its meteorological volume fraction, and veri ed the high-pressure phenomenon caused by cavitation collapse, which is used to achieve processing. Then, we investigated the blanking form ability of cavitation jet on T2 copper foils to cope with different shapes. The impact of the incident pressure of cavitation jet and targeted distance on the micro blanking form ability is studied, and the experimental results are correlated with the simulation. Also, we observed a linear relation between the critical blanking thickness and blanking size of T2 copper foil. Through the characterization of the experimental results, it is found that the internal stress of the regular polygon-shaped blanking parts is unevenly distributed along the blanking contour during processing, which is easy to cause the material to tear and produce defects like aws and incomplete forming. On the other hand, the internal stresses of the circular blanking parts are evenly distributed along the blanking contour, which shows that the blanking forming has good quality. This processing technology is different from traditional plastic micro blanking processing, the cut edge morphology of micro blanking parts under cavitation jet technology is mainly bending and pulling, without obvious shearing marks. Under moderate incident pressure, the cut edge of the blanking part has few pulling marks and small burrs, and has good and uniform blanking quality.
