| Abstract | ||||
| Electrochemical machining [ECM), offers the unique advantage of a better accuracy and high surface integrity of hard machined components. A new technique has been developed to utilize a simultaneous moving and rotating electrode to remove a specific amount of material, from a pre-machined holes and rods of hardened steel specimens. One of the electrodes was provided with two simultaneous movements; traverse speed and rotational speed. The electrolyte was pumped into the gap between tool and workpiece, through a matrix of fine holes distributed along one of the electrode surfaces. A mathematical model has been proposed for accurately estimating the thickness the removed workpiece layer under different working conditions. Experimental results revealed that this technique could lead to the removal of a surface layer thickness up to 200 microns, which consequently, classified this method as a super finishing process. Finally, the results of the experiments and the simulation are compared to each other. The obtained results are an endeavor to enhance the controllability of the ECM process. | ||||
