Jet Electrolytic Drilling (JED) is a micro-hole drilling process, which employs a jet of electrolyte for anodic dissolution of workpiece material and does not require entry of a nozzle into the machined hole. JED has been used for drilling small holes in aerospace, electronic, and micro-mechanics. One of the most significant problems on JED is the precise control and parameters optimization of the process. This paper established a two-dimension mathematical model for JED to describe the shape of the drilled hole. The model was validated by comparison of simulation and experimental result. JED experiments were performed on 0.6mm thickness stainless steel sheets with different parameters including nozzle diameter and operating voltage. It is found that JED is suitable for drilling micro-holes with diameter less than 1mm and the operating voltage should better be more than 120V.
