4. Tests are performed to determine the Tool Life of a high speed steel single edge cutting tool. At a cutting speeds (v) of 180
podryga [215]

Answer:(a)   n=0.233

Step-by-step explanation:

Given

We Know according to Taylor tool life

VT^n=c

V=cutting speed

T=tool life

n=tool life exponent

c=constant

180\times \left ( 4.25\right )^n=110\times \left ( 35\right )^n

\frac{180}{110}=\left ( \frac{35}{4.25}\right )^n

1.636=\left ( 8.235\right )^n

taking log both side

\ln \left ( 1.636\right )=n\ln \left ( 8.235\right )

n=0.233
