Volume of crater from MRR Solution

Follow our step by step solution on how to calculate Volume of crater from MRR?

FIRST Step Consider the formula

V = \frac{Z w}{f c}

Next Step Substitute values of Variables

∴

V = \frac{80m³/s}{1600cycle/s}

Next Step Convert Units

∴

V = \frac{80m³/s}{1600Hz}

Next Step Prepare to Evaluate

∴

V = \frac{80}{1600}

Next Step Evaluate

∴

V = 0.05m²

LAST Step Convert to Output's Unit

∴

V = 50000mm²

Go Material removal rate, MRR

MRR = - \frac{K mrr \cdot {V c}^{2}}{2 \cdot R c \cdot \ln (1 - (\frac{V c}{V 0}))}

Go Proportionality constant for MRR

K mrr = - \frac{MRR \cdot (2 \cdot R c \cdot \ln (1 - (\frac{V c}{V 0})))}{{V c}^{2}}

Go Resistance of circuit

R c = - \frac{K mrr \cdot {V c}^{2}}{2 \cdot MRR \cdot \ln (1 - (\frac{V c}{V 0}))}

Go Input power supply to achieve given MRR

V 0 = \frac{V c}{1 - \exp (- \frac{K mrr \cdot {V c}^{2}}{2 \cdot R c \cdot Z w})}
