Ultimate tensile strength of work piece material Solution

STEP 0: Pre-Calculation Summary

Formula Used

Ultimate Tensile Strength = (3.25*Sparking time*Mean Current Setting^(3/2))/Volume of Crater
S_ut = (3.25*τ_s*I_m^(3/2))/V
This formula uses 4 Variables

Variables Used

Ultimate Tensile Strength - (Measured in Pascal) - Ultimate Tensile Strength (UTS) is the maximum stress that a material can withstand while being stretched or pulled.
Sparking time - (Measured in Second) - Sparking time is defined as the time for which a spark is sustained.
Mean Current Setting - (Measured in Ampere) - Mean current setting is the current set to mean current value during unconventional machining of EDM.
Volume of Crater - (Measured in Square Meter) - Volume of crater is defined as the Volume of crater made by an electric spark during EDM.

STEP 1: Convert Input(s) to Base Unit

Sparking time: 8 Second --> 8 Second No Conversion Required
Mean Current Setting: 0.5 Ampere --> 0.5 Ampere No Conversion Required
Volume of Crater: 3 Square Millimeter --> 3E-06 Square Meter (Check conversion here)

STEP 2: Evaluate Formula

Substituting Input Values in Formula

S_ut = (3.25*τ_s*I_m^(3/2))/V --> (3.25*8*0.5^(3/2))/3E-06

Evaluating ... ...

< 5 Volume of crater made by an electric spark Calculators

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

Ultimate tensile strength of work piece material Formula

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

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.
