Question: Using the Taylor equation VTn = C, calculate the percentage increase in tool life when the cutting speed is reduced by 50% (n = 0∙5 and C = 400). [IAS 2002] This is a simple problem based on the Taylor equation of tool life. The Taylor’s Tool Life equation provides an exponential relationship between the cutting velocity and tool life, as given below. The V indicates cutting velocity (m/min),
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.
Question: In the Taylor’s tool life equation, VTn = C, the value of n = 0.5. The tool has a life of 180 minutes at a cutting speed of 18 m/min. If the tool life is reduced to 45 minutes, then what will be the cutting speed? [IAS 1997] This is one simple problem based on Taylor’s Tool Life equation where one combination of velocity and life is given. It
