- In conventional metal cutting process,tool wear is inevitable.Explain why cutting tool failure due to tool wear is difficult to predict.(Write it broadly in your own words)arrow_forwardA turning machining experiment was performed at the UCSI University's Mechanical Engineering workshop using a lathe machine with palm oil as lubricant. It was observed that during the entire machining, the technician set cutting tool perpendicular to the direction of tool motion. A further investigation revealed that the tool rake angle was 25° while the dynamometer results' analysis showed that the frictional force and the normal force to the friction was 5 kN and 25 kN respectively. Analyze how the chip thickness will be affected if the machining is performed without any lubricant and the frictional force is increased by 100 %. Assume that, all other parameters were kept constant during the entire operation for both machining with lubricant and the dry machining process.arrow_forwardIdentify some of the reasons why machining is commercially and technologically important.arrow_forward

- 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.arrow_forwardIn 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 25 m/min.
