Unconventional machining processes are used only when no other traditional machining process can meet the necessary requirements efficiently and economically. Determinations of machining parameters are essential for the effective utilization of these processes. Electric Discharge Machining (EDM) is a thermo-electric.
The lack of correlations between the cutting rate, the surface finish and the physical material parameters of this process made it difficult to use. This paper highlights the development of a comprehensive mathematical model for correlating the interactive and higher order influences of various electrical discharge machining.
Apr 6, 2016 . The electrical discharge machining conditions selected for this work can be shown in Table 3. EDM cutting parameters such as material removal rate, electrode wear rate, gap size and surface roughness were evaluated when cylindrical cavity of 1.0 mm in depth was machined as shown in Figure 2.
In the first category, the main parameters to choose from at setup time are the resistance(s) of the resistor(s) and the capacitance(s) of the capacitor(s). In an ideal condition these quantities would affect the maximum current delivered in a discharge which is expected to.

discharge parameters, but distributed following a Weibull distribution. This shows that the breakdown is of stochastic nature. After the breakdown, the plasma develops very rapidly (< 50 ns) and then remains stable. The plasma light is particularly intense during the first 500 ns after the breakdown and weaker during the rest.
