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