Abstract
This paper describes micro electrochemical machining (ECM) of curved patterns using shaped electrolyte jet. In electrolyte jet machining (EJM), the workpiece is machined locally in the area hit by the jet. To fabricate a curved groove without translating a cylindrical jet, a novel slit nozzle with curvature was developed. The machining characteristics of the curved slit nozzle were investigated experimentally, and it was found that curved grooves similar to the cross section of the jet can be machined. The electric potential distribution in the electrolyte flow and the current density distribution over the workpiece surface were calculated and compared with those of a cylindrical nozzle.
