Material Removal Rate during Drilling Operation using Feed Solution

Follow our step by step solution on how to calculate Material Removal Rate during Drilling Operation using Feed?

FIRST Step Consider the formula

Z d = \frac{π \cdot {d m}^{2} \cdot f d \cdot n t}{4}

Next Step Substitute values of Variables

∴

Z d = \frac{π \cdot {55mm}^{2} \cdot 3.01mm/rev \cdot 793rev/min}{4}

Next Step Substitute values of Constants

∴

Z d = \frac{3.1416 \cdot {55mm}^{2} \cdot 3.01mm/rev \cdot 793rev/min}{4}

Next Step Convert Units

∴

Z d = \frac{3.1416 \cdot {0.055m}^{2} \cdot 0.003m/rev \cdot 83.0428rad/s}{4}

Next Step Prepare to Evaluate

∴

Z d = \frac{3.1416 \cdot {0.055}^{2} \cdot 0.003 \cdot 83.0428}{4}

Next Step Evaluate

∴

Z d = 0.000593859298887292m³/s

LAST Step Rounding Answer

∴

Z d = 0.0006m³/s
