A number of through holes with 10-mm-diameter have been drilled through 30-mm thick cast iron plate. At a cutting speed of 25 m/min, the high-speed steel drill tool lasted for 44 holes. But, when the cutting speed increased to 35 m/min, the drill tool lasted for only five holes. The feed used in the both cases is 0.08 mm/rev. Determine the values of n and Cin the Taylor tool life equation for the data, where cutting speed v is expressed in m/min, and tool life T is expressed in min.

Machining Processes and Machine Tools

Machining is represented as the process in which an excessive amount of substance is eliminated from the particular element in the form of pieces. In machining, cutting tools such as rotary tools, lathe, drill press, grinder, chop saw, welders, and many more are applied to get the desired shape. As compared to other manufacturing processes, machining is precise and versatile.
