“…Therefore, diverse advanced machining methods, such as Linear Friction Welding (LFW) [2], Electro Discharge Machining (EDM) [3], and Electrochemical Machining (ECM) [4] are introduced into blisk process. Especially, due to characteristics of non-existent tool wear and short process-time, ECM plays a prominent role in the blisk process [5]. Lots of efforts have been devoted to blisk ECM.…”

Electrochemical machining plays a prominent role in blisk (bladed integrated disk) construction process. Since blisk channel is narrow and twisted, interference between electrodes may happen during electrochemical machining. Therefore, this paper develops a cathode designing method to avoid interference. Firstly, according to theory of electrochemical machining, machined channel is predicted by calculation. Second, with this channel, interference analysis is carried out and a cathode is designed. Finally, the cathode is employed in experiment and no interference appears.

This study investigates the feasibility of using electrochemical machining (ECM) to produce critical aeroengine components from a new burn-resistant titanium alloy (Ti40), thereby reducing costs and improving efficiency relative to conventional mechanical machining. Through this, it is found that an aqueous mix of sodium chloride and potassium bromide provides the optimal electrolyte and that the surface quality of the Ti40 workpiece is improved by using a pulsed current of 1 kHz rather than a direct current. Furthermore, the quality of cavities produced by ECM and the overall material removal rate are determined to be dependent on a combination of operating voltage, electrolyte inlet pressure, cathode feeding rate and electrolyte concentration. By optimizing these parameters, a surface roughness of 0.371 lm has been achieved in conjunction with a specific removal rate of more than 3.1 mm 3 /AAEmin.

Electrochemical machining (ECM) is an economical and effective method for machining hard-to-cut metal materials into complex shapes in aerospace and aeronautics fields, which are difficult to machine with conventional methods. As we all know, electrolyte flow field is one of the important factors in ECM irregular vortex paths of the closed integer impeller. To improve the stability of the whole processing, the flow field mathematical model was developed. The 3-D gap flow field simulation models of the reversed flow and forward flow patterns were also established, respectively. From the streamline, velocity, and pressure cloud picture of the electrolyte flow field simulation, the results showed that under the reversed pattern, the electrolyte flow velocity in the front gap and the side gap was not only higher but also more uniform than the forward pattern. Finally, the experimental verification was carried out and the experimental results were consistent with the simulation results. The whole process is stable and has no spark and no short circuit phenomenon with the reverse flow pattern. We successfully obtained 0.8-micron surface roughness of the machined workpiece. On the contrary, the irregular vortex paths cannot be successfully processed by forward flow pattern. The results indicate that reverse flow pattern is an effective and feasible method to machining irregular vortex paths of the closed integer impeller.
