Calculate the value of Taylorian Exponent of tool life in machining
Question: A 50 mm diameter steel rod was turned at 284 rpm and tool failure occurred in 10 minutes. The speed was changed to 232 rpm and the tool failed in 60 minutes. Assuming straight line relationship between cutting speed and tool life, calculate the value of Taylorian Exponent (n). [ISRO 2011] Tool life indicates the duration of time within which a cutting tool provides satisfactory performance in machining. Taylor’s
