2. A series of turning tests were conducted using cemented carbide cutting tool at a given machining conditions under a given environment (cutting fluid applications).Its Speed was 165m/min at a tool life of 9 min and 130 m/min at a life of 15 min. (a) on a piece of natural log-log paper, plot your results from the plot, determine the values of n[slope of the line] and C in the Taylor Tool Life Equation (b) As a comparison, calculate the values of n and C in the Taylor equation solving simultaneous equations. Are the resulting n and C values the same?
