Experimental Investigation on Micro Electrochemical Milling of Nickel-Based Superalloy

Abstract:

In this paper, sets of experiments are carried out on the difficult-to-machine nickel-based superalloy based on the principle of micro electrochemical milling with nanosecond pulse current. First, an experimental system for meeting the requirements of the EMM process is established. Second, sets of experiments are carried out to investigate the influence of some of the predominant electrochemical process parameters, such as machining voltage, pulse on time, and electrolyte concentration, on machining accuracy. Finally, using the optimization parameters, a series of 2D and 3D micro structures have been successfully obtained.
