## Volume of crater related to mean current setting Solution

STEP 0: Pre-Calculation Summary
Formula Used
Volume of crater = (3.25*10^6/Ultimate Tensile Strength)*Sparking time*Mean current setting^(3/2)
V = (3.25*10^6/Sut)*τs*Im^(3/2)
This formula uses 3 Variables
Variables Used
Ultimate Tensile Strength - Ultimate tensile strength (UTS) is the maximum stress that a material can withstand while being stretched or pulled. (Measured in Megapascal)
Sparking time - Sparking time is defined as the time for which a spark is sustained. (Measured in Second)
Mean current setting - Mean current setting is the current set to mean current value during unconventional machining of EDM. (Measured in Ampere)
STEP 1: Convert Input(s) to Base Unit
Ultimate Tensile Strength: 100 Megapascal --> 100000000 Pascal (Check conversion here)
Sparking time: 10 Second --> 10 Second No Conversion Required
Mean current setting: 1 Ampere --> 1 Ampere No Conversion Required
STEP 2: Evaluate Formula
Substituting Input Values in Formula
V = (3.25*10^6/Sut)*τs*Im^(3/2) --> (3.25*10^6/100000000)*10*1^(3/2)
Evaluating ... ...
V = 0.325
STEP 3: Convert Result to Output's Unit
0.325 Square Meter -->325000 Square Millimeter (Check conversion here)
325000 Square Millimeter <-- Volume of crater

## 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.
