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.
Identify the various machine tools used in industry and explain the importance of each machine tool.
In a cutting test with 0.3 mm flank wear as tool
failure criterion, a tool life of 10 min was obtained
at a cutting velocity of 20 m/min. Taking tool life
exponent as 0.25, the tool life in minutes at 40
m/min of cutting velocity will be
