How the spark is produced in Electric Discharge Machining ?
A typical circuit used for supplying the power to an EDM machine is named as the relaxation circuit. The circuit consists of a DC power source, which charges the capacitor ‘C’ across a resistance ‘Rc’. Initially when the capacitor is in the uncharged condition, when the power supply is on with a voltage of Vo, a heavy current, ic, will flow in the circuit as shown to charge the capacitor. The relaxation circuit as explained above was used in the early EDM machines. They are limited to the low material removal rates for fine finish, which limits its application. This can be explained from the fact that the time spent on charging the capacitor is quite large during which time, no machining can actually take place. Thus the material removal rates are low.
How to Calculate Voltage of Charging Circuit Max Spark Current?
Voltage of Charging Circuit Max Spark Current calculator uses Charging Voltage = Maximum Current*sqrt(Inductance of Maximum Spark/Capacitance of Maximum Spark) to calculate the Charging Voltage, Voltage of charging circuit max spark current formula is defined as the voltage at which the capacitor of charging circuit is being charged. Charging Voltage is denoted by Vmaxspark symbol.
