Traveling wire electrochemical machining is a promising approach for the fabrication of various metal parts. However, the stray-current attack deteriorates the surface quality while it is employed to cut thick workpiece as a normal pulse or DC is used. In this paper, the characteristics of the stray-current attack in reciprocated traveling wire electrochemical machining are firstly identified, and special insulating methods are proposed to reduce the effect of the stray-current. The model of electric field is built. Both the simulation and the experimental results illustrate that the stray-current attack can be reduced significantly by the proposed insulating methods. Finally, structures with fine surface quality on stainless steel 304 with thickness of 20 mm were successfully produced.
