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 Energy Delivered per Spark?
Energy Delivered per Spark calculator uses Energy Delivered per Spark in Energydel/spark = 0.5*Capacitance Energydel/Spark*Voltage at Any Time t Energydel/spark^2 to calculate the Energy Delivered per Spark in Energydel/spark, The Energy delivered per spark formula is defined as the parameter which defines the amount of material removed and the surface finish produced. Energy Delivered per Spark in Energydel/spark is denoted by Peds symbol.
How to calculate Energy Delivered per Spark using this online calculator? To use this online calculator for Energy Delivered per Spark, enter Capacitance Energydel/Spark (Ceds) & Voltage at Any Time t Energydel/spark (Veds) and hit the calculate button. Here is how the Energy Delivered per Spark calculation can be explained with given input values -> 12 = 0.5*6*2^2.
