J. Watson Research Center of IBM apart from other research institutions. However, to exploit the full potential of EMM, research is still needed to improve its accuracy and compactness. The importance of EMM in the area of micromachining and nanofabrication and the recent improvements in accuracy and material removal in the micro and nanodomains have been highlighted in Chapters 8 and 12, respectively. Basic principles are discussed in Chapter 3, and recent developments in EMM setup are also explained in Chapter 5.
The technique was applied mainly for machining of large components made of advanced and difficult-to-cut metals in the 1960s and the 1970s, particularly in the gas turbine industry. Electrical discharge machining at that time was a more accurate technique and was preferred over ECM, because ECM was less accurate and its waste is hazardous to the environment. But ECM was able to achieve much higher machining speed. Rapid development of a wide range of electrochemical machines by several manufacturers in the United States, Europe, and Japan made the process more popular with confidence due to several advantages such as quality, flexibility, and cost.
When current, resistance, and time are expressed in amperes, ohms, and seconds, respectively, the unit of H is the Joule. The heating effect of conductors carrying currents is known as Joule heating. Joule heating is also important in ECM; due to the current flow the electrolyte gets heated, which changes its conductivity. According to Ohm’s law in an electrical circuit, conducted current is proportional to the voltage applied across it. Ohm’s law states that for a voltage V across a circuit of resistance R, the current will be: V ¼ I$R ð2:14Þ Since the power dissipated by a resistor is the amount of energy used (electrical work applied) per unit time, the total energy consumed and dissipated in time t is: V2 $t ð2:15Þ R Generation of heat due to the flow of current changes the resistance across the IEG, which influences the amount of current flow.
