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