What factors affects surface finish during EDM ?
The amount of material removed and the surface finish produced is dependent upon the current in the spark. The material removed by the spark can be assumed to be a crater. The amount removed therefore will depend upon the crater depth, which is directly proportional to the current. Thus as the material removed increases and at the same time, the surface finish also decreases. However, decreasing the current in the spark, but increasing its frequency will improve the surface finish in view of the small crater size, but at the same time, the material removal rate can be maintained by increasing the frequency.
How to Calculate Overcut produced per side?
Overcut produced per side calculator uses Overcut in mm per side = (Overcut Constant A*Capacitance in Surface Defect^0.333)+Overcut Constant B to calculate the Overcut in mm per side, The Overcut produced per side formula is defined as the length of extra material removed due to side sparks in mm per side of electrode. Overcut in mm per side is denoted by O symbol.
How to calculate Overcut produced per side using this online calculator? To use this online calculator for Overcut produced per side, enter Overcut Constant A (A), Capacitance in Surface Defect (Csd) & Overcut Constant B (B) and hit the calculate button. Here is how the Overcut produced per side calculation can be explained with given input values -> 5 = (1.4*5.70416541^0.333)+2.5.
