Abstract:Electrochemical trepanning is an economical approach for machining straight blades made of hard to cut materials. However, the stray corrosion caused by cathode tip in traditional electrochemical trepanning process, may introduce a tapered wall of fabricated blade. In this paper, a modified electrochemical trepanning process with a pictographic insulation sleeve based on the lateral flow mode is proposed to reduce the taper of blade. Computer-aided optimization method was investigated to optimize the protruding length of pictographic insulation sleeve. Finally, a series of experiments were carried out and results showed that the taper angle of fabricated blade has been reduced from 0.286 to 0.106, when protruding length of the pictographic insulation sleeve improved from 0 to 0.4 mm.
