Taylor’s Tool Life curve when tool life increases 16 times if the cutting speed is halved

Question: In a single-point turning operation of steel with a cemented carbide tool, Taylor’s tool life exponent is 0.25. If the cutting speed is halved, how many times the tool life will increase? [ISRO 2013, IAS 1995] This problem can be solved using well-known Taylor’s Tool Life equation which provides the exponential relationship between cutting velocity and tool life. The generalized form of Taylor’s Tool Life equation is shown below.
