Discuss three (3) advantages of using cutting fluids in machining operation.
Explain the distinct features of non-conventional machining which gave it superiority over the conventional machining?
In machining a mild steel work piece with carbide tool, the life of the tool was
found to be 1 hour and 40 minutes, at a spindle speed of 30 m/min. Calculate the
tool life if it has to be operated at a speed of 40% higher than the initial cutting
speed. Also calculate the cutting speed if the tool is required to have a life of
2 hours and 45 minutes. Assume Taylor's exponent valuen is 0.28.
