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 Largest size of hole given taper?
Largest size of hole given taper calculator uses Larger Diameter = 2*Depth of Machined Surface*Taper Produced in EDM+Smaller Diameter to calculate the Larger Diameter, Largest size of hole given taper formula is defined as width of crater produced on upper surface in EDM. Larger Diameter is denoted by Dsd symbol.
How to calculate Largest size of hole given taper using this online calculator? To use this online calculator for Largest size of hole given taper, enter Depth of Machined Surface (Hsd), Taper Produced in EDM (Tsd) & Smaller Diameter (d) and hit the calculate button. Here is how the Largest size of hole given taper calculation can be explained with given input values -> 3.48 = 2*52*0.2+1.2.
