Simulation and experimental of array microtexturing based on porous nozzle technology

In response to the significant shortcomings of the single-hole nozzle system for jet electrolytic machining, which is not applicable to the field of manufacturing large-scale surface micro-weave structures, a porous strip nozzle machining process is proposed. The porous nozzle structure was fabricated using 3D printing technology, which is not limited by the processing structure, and the jet electrolysis machining device was constructed. Comsol software was used to simulate the flow field and electric field, and the flow channel inside the nozzle cavity was optimised based on the evaluation of the flow rate from the nozzle to the surface of the workpiece and the current density. The study shows that the bar nozzle structure can form a stable jet to achieve efficient machining of the workpiece. The peak material removal rate was achieved at a machining voltage of 475 V and a duty cycle of 70%.
