Machining Time for Workpiece given Roughness Solution

Follow our step by step solution on how to calculate Machining Time for Workpiece given Roughness?

FIRST Step Consider the formula

t m = 0.18 \cdot \frac{L}{n w \cdot {(r E \cdot R a)}^{0.5}}

Next Step Substitute values of Variables

∴

t m = 0.18 \cdot \frac{400mm}{10Hz \cdot {(1.5mm \cdot 0.0175mm)}^{0.5}}

Next Step Convert Units

∴

t m = 0.18 \cdot \frac{0.4m}{10Hz \cdot {(0.0015m \cdot 1.8E-5m)}^{0.5}}

Next Step Prepare to Evaluate

∴

t m = 0.18 \cdot \frac{0.4}{10 \cdot {(0.0015 \cdot 1.8E-5)}^{0.5}}

Next Step Evaluate

∴

t m = 44.4000564251076s

Next Step Convert to Output's Unit

∴

t m = 0.740000940418459min

LAST Step Rounding Answer

∴

t m = 0.74min
