Here each and every mechanical engineering subject questions are given topic by topic. 1 / 25 Crater wear occurs at None of the mentioned Tool flank Tool shank Tool face 2 / 25 Which of the following tools is most suitable for very hard and brittle material? None of the mentioned HSS Cast-cobalt alloy Carbides 3 / 25 High speed steels are most suitable for High Negative rake angle tools Zero Rake angle tools None of the mentioned High Positive rake angle tools 4 / 25 Angle between side cutting edge and axis of tool is known as: Side relief angle Side rake angle Back rake angle Side cutting edge angle 5 / 25 What is the optimum value of side cutting edge in degrees for maximum tool life? 30 22 20 25 6 / 25 For large negative back rake angle, tool will be Smoother Stronger Harder Weaker 7 / 25 Which of the following material can be used for coating on tools? WC (tungsten carbide) TiCN (Titanium Carbo-Nitride) cBN (cubic boron nitride) HSS (high speed steel) 8 / 25 For machining of carbide material which of the following tool will be preferred? Large negative rake angle tools Small point angle tools Large positive rake angle tools Zero rake angle tools 9 / 25 Mechanical chipping may occur in which of the following tool? HSS tool Diamond tool Mild Steel tool None of the mentioned 10 / 25 For large positive back rake angle, tool will be Smoother Harder Stronger Weaker 11 / 25 With an increase in side cutting edge angle keeping width of cut constant, depth of cut will Increase First increase then decrease Remains constant Decrease 12 / 25 What is the optimum value of positive rake angle in degrees for maximum tool life? 10 20 15 12 13 / 25 Angle between end cutting edge and axis of tool is known as: Side rake angle End cutting edge angle Side relief angle Back rake angle 14 / 25 Angle between side cutting edge and end cutting edge in the top surface plane of tool. Nose angle Side cutting edge angle Side rake angle Side relief angle 15 / 25 Which of the following will give maximum chip flow during machining? All of the mentioned Ductile material Brittle material Hard material 16 / 25 With an increase in lip angle keeping side rake angle constant, strength of tool. Remains constant Increases None of the mentioned Decreases 17 / 25 Which of the following will give large friction during chip flow? Small lip angle tool Zero back rake angle tool Positive back rake angle tool Negative back rake angle tool 18 / 25 Angle between the rake face flank of tool and perpendicular line drawn from cutting point to base of tool is known as: Side rake angle Back rake angle End relief angle Side relief angle 19 / 25 Angle between the rake face and plane perpendicular to rake face is known as: Side rake angle Back rake angle End relief angle Side relief angle 20 / 25 Flank wear occurs at Tool shank Tool face Tool flank below cutting edge None of the mentioned 21 / 25 If a percentage of cobalt in Tungsten carbide tool increases, then toughness of tool will Increase First increase then decrease Remains Constant Decrease 22 / 25 Positive rake angle is given for machining of: None of the mentioned Ductile material Brittle material Both hard and soft material 23 / 25 Negative back rake angle is given for machining of: Ductile material Soft and ductile material Soft material Brittle and hard material 24 / 25 Which of the following will give better chip flow?
