Number of Tools given Non-Productive Time in Turning Solution

Follow our step by step solution on how to calculate Number of Tools given Non-Productive Time in Turning?

FIRST Step Consider the formula
Nt=(NPT-tln-(tptn0))Nb-tstst
Next Step Substitute values of Variables
Nt=(28.169min-30s-(1.5min5))3-20.5min10min
Next Step Convert Units
Nt=(1690.14s-30s-(90s5))3-1230s600s
Next Step Prepare to Evaluate
Nt=(1690.14-30-(905))3-1230600
LAST Step Evaluate
Nt=4.0007
