Machining of pure molybdenum using WEDM

Experimental Investigation of Wire-EDM Machining of Low Conductive Al-SiC-TiC Metal Matrix Composite

“…The MRR value in the WEDM machining cycle is given as the product of kerf width, cutting speed, and thickness of the sample. The cutting speed was found as the inverse of the cutting time measured during the experiment cycle [16]. It is ascertained from Figure 10 and Table 11, for both the cases of dielectric medium with a surge in Ton, Toff, and peak current the MRR rate improved drastically.…”

“…The MRR value in the WEDM machining cycle is given as the product of kerf width, cutting speed, and thickness of the sample. The cutting speed was found as the inverse of the cutting time measured during the experiment cycle [16]. From Table 11 and Figure 10, it is observed that there was a surge of kerf width, material removal rate, and surface roughness in an oil + wax + paraffin environment in correlation with deionized water by 0.99-12.78%, 0.18-33.97%, and 2.15-36.86% respectively.…”

“…is disposed into the machining cycle to flush out the machined material, again varied by the discharge control unit [15]. For engineers to avail WEDM substantially higher in comparison with other unconventional operations, as indicated in Figure 1 corresponds to simple profounding reasons, viz., the nature of machining is independent of the workpiece material (conductive in nature), thickness of the specimen, and economical and accurate cutting cycles [16][17][18]. These enhanced features makes the machining of high end steels, super alloys (Ni, Al, and Ti based) and metal matrix composites easier in correlation to other unconventional and conventional techniques [17][18][19].…”

“…These dictate the flushing factor in the machining cycle and play an important role in the final output delivered by the cycle of WEDM cutting [14,17]. Experiments were carried out to study the optimization of electrical discharge machining (EDM) parameters peak current, pulse time (on/off) with respect to the roughness form [16]. Statistical attributes corresponding to machining parameters of WEDM were carried out in correlation to surface roughness [17].…”

“…An empirical understanding of the method was Material removal rate (MRR) and roughness of the surface (R a : average factor) are the most prominent characteristics of the WEDM process, which distinguishes the process along with the factors associated with the machining cycle and the dielectric availed for conducting the machining operation [14]. Two disparate types of dielectrics are availed, i.e., organic and inorganic based on the requirement and feasibility of the process [16]. These dictate the flushing factor in the machining cycle and play an important role in the final output delivered by the cycle of WEDM cutting [14,17].…”
