Question

If the Taylor's tool life exponent $n$ is $0.2$ , and the tool changing time is $1.5 m i n$ , then the tool life (in $m i n$ ) for maximum production rate is

Open in App

Solution

Given, $n = 0.2$
$T_{c t} = 1.5 m i n$
Tool life for maximum production rate,
$= (\frac{1}{n} - 1) T_{C t}$
$∴$ Tool life $= (\frac{1}{0.2} - 1) \times 1.5$
$= 4 \times 1.5 = 6 m i n u t e s$
