In this work, the process of micro-channels in electrochemical micro-milling by using rotating magnet assisted helical tool is presented. The results show helical tool and Lorentz force of the rotating magnetic field that enhance the renewal of the electrolyte and machining efficiency. The feed rate can be raised under the magnetic field assisted in terms of experimental results; moreover, the surface roughness also can be reduced. The study reveals that the magnetic field assisted approach indeed can improve machining efficiency, accuracy and surface roughness. COMSOL Multiphysics is utilized to simulate with discharged voltage and the results are compared with experimental results.
