“…Pulsed electrochemical machining (PECM) is a promising micromachining technique for fabricating microstructures. PECM has several advantages, including a cheaper set-up, no tool wear, no residual stress, higher machining rate, better precision, and applicability to any conductive material, regardless of hardness [7][8][9][10][11][12].…”

Pulsed electrochemical machining (PECM) has been conducted for invar (Fe-Ni) fine sheet consisting of 64 % Fe ions and 36 % Ni ions. Solutions of sodium chloride (NaCl), acetic acid (CH 3 COOH), sodium nitrate (NaNO 3 ), and sodium nitrite (NaNO 2 ) mixed with sodium tartrate (C 4 H 4 Na 2 O 6 ) were used as an electrolyte. First, the electrical conductivities of all electrolytes have been measured. As the concentration of each electrolyte increased, the electrical conductivities of electrolytes increased except for the acetic acid. The electrochemical machinability has been investigated using four types of electrolytes. The results of PECM show that the electrolyte which has the high electrical conductivity value leads to the low electrochemical machinability. The pulse waves which indicate the electrical characteristics during the PECM has been observed and it is confirmed that the passivating oxide film occur in PECM. To compare the capability of changing in transpassive state, the anode surface has been investigated. This study presents the relationship between electrical conductivity and electrical machinability. Moreover, the capacity of changing in transpassive state has been investigated as compared with four types of electrolytes. This study shows the possibility of applying invar fine sheet in PECM and contributes to determining the electrolyte for the process.

“…Fortunately, as one of the non-traditional methods, electrochemical machining (ECM) technology has the merit of high efficiency, good surface quality, no stress, and no cathode wear [6][7][8][9][10][11], which is widely used in machining turbine disk, diffuser, and high-compression engines in aviation and aerospace fields. These components or parts are exceedingly difficult to process by traditional machining methods [12].…”

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.
