Experimental Investigation on Analysis of Taper Angle of Micro-Holes Machined on Inconel 718 by Electrochemical Micromachining
This paper focuses on the overview of electrochemical machining (ECM) process along with its principles. It is also focused on the literature survey to discuss various advantages, disadvantages and applications of ECM. One of the challenging tasks to modern machining processes is machining of Inconel 718, Inconel 625, Titanium alloy, SS 304 etc. As a research point of the fabrication of microfeatures on such a harder material is quite difficult. ECMM is important technology for micromachining due to its some of the advantages such as no stress generation, high material removal rate (MRR) without tool wear etc. The results shown post micromachining processes mainly depends on the different parameters such as Voltage, Feed rate, duty cycle, current density, type of electrolyte and concentration of the electrolyte. There are many different types of tools which can be used are available such as Copper-Tungsten (Cu-W) alloy, ceramics and CBN tool and so on.
