Material Removal Rate during Drilling Operation Solution

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

FIRST Step Consider the formula

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

Next Step Substitute values of Variables

∴

Z d = \frac{π}{4} \cdot {55mm}^{2} \cdot 0.25m/s

Next Step Substitute values of Constants

∴

Z d = \frac{3.1416}{4} \cdot {55mm}^{2} \cdot 0.25m/s

Next Step Convert Units

∴

Z d = \frac{3.1416}{4} \cdot {0.055m}^{2} \cdot 0.25m/s

Next Step Prepare to Evaluate

∴

Z d = \frac{3.1416}{4} \cdot {0.055}^{2} \cdot 0.25

Next Step Evaluate

∴

Z d = 0.00059395736106932m³/s

LAST Step Rounding Answer

∴

Z d = 0.0006m³/s
