Small lip angle tool Negative back rake angle tool Zero back rake angle tool Positive back rake angle tool 4 / 25 Positive rake angle is given for machining of: Both hard and soft material None of the mentioned Brittle material Ductile material 5 / 25 Crater wear occurs at None of the mentioned Tool face Tool shank Tool flank 6 / 25 Flank wear occurs at Tool flank below cutting edge Tool face None of the mentioned Tool shank 7 / 25 Which of the following material can be used for coating on tools? WC (tungsten carbide) HSS (high speed steel) TiCN (Titanium Carbo-Nitride) cBN (cubic boron nitride) 8 / 25 Angle between side cutting edge and end cutting edge in the top surface plane of tool. Side rake angle Side relief angle Nose angle Side cutting edge angle 9 / 25 With an increase in lip angle keeping side rake angle constant, strength of tool. Remains constant Increases None of the mentioned Decreases 10 / 25 With an increase in side cutting edge angle keeping width of cut constant, depth of cut will First increase then decrease Decrease Remains constant Increase 11 / 25 Angle between side cutting edge and axis of tool is known as: Side cutting edge angle Side rake angle Side relief angle Back rake angle 12 / 25 Which of the following is correct about crater wear? None of the mentioned Occurs more in brittle tool Occurs more in soft tool Occurs more hard tool 13 / 25 For large positive back rake angle, tool will be Harder Weaker Stronger Smoother 14 / 25 Negative back rake angle is given for machining of: Soft material Ductile material Soft and ductile material Brittle and hard material 15 / 25 What is the optimum value of side cutting edge in degrees for maximum tool life? 25 30 22 20 16 / 25 If a percentage of cobalt in Tungsten carbide tool increases, then toughness of tool will Increase Decrease First increase then decrease Remains Constant 17 / 25 What is the optimum value of positive rake angle in degrees for maximum tool life? 10 20 12 15 18 / 25 Which of the following will give maximum chip flow during machining?
