Diameter of crater Solution

STEP 0: Pre-Calculation Summary

Formula Used

Larger Diameter = sqrt((8*(Volume of Crater-(pi/6)*Depth of Machined Surface^3))/(pi*Depth of Machined Surface))
D = sqrt((8*(V-(pi/6)*H^3))/(pi*H))
This formula uses 1 Constants, 1 Functions, 3 Variables

Constants Used

pi - Archimedes' constant Value Taken As 3.14159265358979323846264338327950288

Functions Used

sqrt - A square root function is a function that takes a non-negative number as an input and returns the square root of the given input number., sqrt(Number)

Variables Used

Larger Diameter - (Measured in Meter) - Larger diameter is the bigger diameter of hole or other things.
Volume of Crater - (Measured in Square Meter) - Volume of crater is defined as the Volume of crater made by an electric spark during EDM.
Depth of Machined Surface - (Measured in Meter) - Depth of machined surface is the how deep a surface is machined from the un-machined surface.

STEP 1: Convert Input(s) to Base Unit

Volume of Crater: 3 Square Millimeter --> 3E-06 Square Meter (Check conversion here)
Depth of Machined Surface: 13 Millimeter --> 0.013 Meter (Check conversion here)

STEP 2: Evaluate Formula

Substituting Input Values in Formula

D = sqrt((8*(V-(pi/6)*H^3))/(pi*H)) --> sqrt((8*(3E-06-(pi/6)*0.013^3))/(pi*0.013))

Evaluating ... ...

Diameter of crater

Go Larger Diameter = sqrt((8*(Volume of Crater-(pi/6)*Depth of Machined Surface^3))/(pi*Depth of Machined Surface))

Mean current setting from crater volume

Go Mean Current Setting = ((Volume of Crater*Ultimate Tensile Strength)/(3.25*Sparking time))^(2/3)

Volume of crater related to mean current setting

Go Volume of Crater = 3.25*10^6/Ultimate Tensile Strength*Sparking time*Mean Current Setting^(3/2)

Discharge duration of single pulse

Go Sparking time = (Volume of Crater*Ultimate Tensile Strength)/(3.25*Mean Current Setting^(3/2))

Ultimate tensile strength of work piece material

Go Ultimate Tensile Strength = (3.25*Sparking time*Mean Current Setting^(3/2))/Volume of Crater

Diameter of crater Formula

Larger Diameter = sqrt((8*(Volume of Crater-(pi/6)*Depth of Machined Surface^3))/(pi*Depth of Machined Surface))
D = sqrt((8*(V-(pi/6)*H^3))/(pi*H))

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.
