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