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 Smallest diameter of hole given empirical constant?
Smallest diameter of hole given empirical constant calculator uses Smaller Diameter = sqrt(Taper Produced in EDM/Empirical Constant) to calculate the Smaller Diameter, Smallest diameter of hole given empirical constant formula is defined as smallest diameter at depth of crater produced during EDM. Smaller Diameter is denoted by d symbol.
How to calculate Smallest diameter of hole given empirical constant using this online calculator? To use this online calculator for Smallest diameter of hole given empirical constant, enter Taper Produced in EDM (Tsd) & Empirical Constant (KT) and hit the calculate button. Here is how the Smallest diameter of hole given empirical constant calculation can be explained with given input values -> 0.4 = sqrt(0.2/0.1388).
