Tool Changing Time for each Tool given Cutting Velocity Solution

Follow our step by step solution on how to calculate Tool Changing Time for each Tool given Cutting Velocity?

FIRST Step Consider the formula

t c = \frac{(C t \cdot \frac{L ref}{{(\frac{V}{V ref})}^{\frac{1}{n}} \cdot \frac{1 - n}{n}}) - C t}{C t}

Next Step Substitute values of Variables

∴

t c = \frac{(48 \cdot \frac{8400min}{{(\frac{420m/min}{2.9961m/min})}^{\frac{1}{0.5408}} \cdot \frac{1 - 0.5408}{0.5408}}) - 48}{48}

Next Step Convert Units

∴

t c = \frac{(48 \cdot \frac{504000s}{{(\frac{7m/s}{0.0499m/s})}^{\frac{1}{0.5408}} \cdot \frac{1 - 0.5408}{0.5408}}) - 48}{48}

Next Step Prepare to Evaluate

∴

t c = \frac{(48 \cdot \frac{504000}{{(\frac{7}{0.0499})}^{\frac{1}{0.5408}} \cdot \frac{1 - 0.5408}{0.5408}}) - 48}{48}

Next Step Evaluate

∴

t c = 62.7001516841988s

Next Step Convert to Output's Unit

∴

t c = 1.04500252806998min

LAST Step Rounding Answer

∴

t c = 1.045min
