Tool Positioning Time per Operation given Non-Productive Time in Turning Solution

Follow our step by step solution on how to calculate Tool Positioning Time per Operation given Non-Productive Time in Turning?

FIRST Step Consider the formula

t pt = \frac{NPT - (\frac{t s + N t \cdot t st}{N b}) - t ln}{n 0}

Next Step Substitute values of Variables

∴

t pt = \frac{28.169min - (\frac{20.5min + 4 \cdot 10min}{3}) - 30s}{5}

Next Step Convert Units

∴

t pt = \frac{1690.14s - (\frac{1230s + 4 \cdot 600s}{3}) - 30s}{5}

Next Step Prepare to Evaluate

∴

t pt = \frac{1690.14 - (\frac{1230 + 4 \cdot 600}{3}) - 30}{5}

Next Step Evaluate

∴

t pt = 90.028s

Next Step Convert to Output's Unit

∴

t pt = 1.50046666666667min

LAST Step Rounding Answer

∴

t pt = 1.5005min
