Here each and every mechanical engineering subject questions are given topic by topic. 1 / 25 Angle between side cutting edge and axis of tool is known as: Side relief angle Side rake angle Side cutting edge angle Back rake angle 2 / 25 Which of the following tools is most suitable for very hard and brittle material? HSS None of the mentioned Cast-cobalt alloy Carbides 3 / 25 Which of the following will give better chip flow? Negative back rake angle tool Zero back rake angle tool Positive back rake angle tool None of the mentioned 4 / 25 Negative back rake angle is given for machining of: Soft and ductile material Brittle and hard material Soft material Ductile material 5 / 25 What is the optimum value of side cutting edge in degrees for maximum tool life? 25 22 30 20 6 / 25 Mechanical chipping may occur in which of the following tool? None of the mentioned Mild Steel tool HSS tool Diamond tool 7 / 25 Which of the following material can be used for coating on tools? cBN (cubic boron nitride) TiCN (Titanium Carbo-Nitride) WC (tungsten carbide) HSS (high speed steel) 8 / 25 Angle between the rake face and plane perpendicular to rake face is known as: Side relief angle Back rake angle End relief angle Side rake angle 9 / 25 For large positive back rake angle, tool will be Weaker Harder Stronger Smoother 10 / 25 High speed steels are most suitable for High Positive rake angle tools High Negative rake angle tools Zero Rake angle tools None of the mentioned 11 / 25 Positive rake angle is given for machining of: Ductile material None of the mentioned Both hard and soft material Brittle material 12 / 25 For large negative back rake angle, tool will be Weaker Smoother Harder Stronger 13 / 25 Angle between end cutting edge and axis of tool is known as: Side relief angle Back rake angle End cutting edge angle Side rake angle 14 / 25 For machining of carbide material which of the following tool will be preferred? Large negative rake angle tools Zero rake angle tools Large positive rake angle tools Small point angle tools 15 / 25 With an increase in side cutting edge angle keeping width of cut constant, depth of cut will Decrease Remains constant First increase then decrease Increase 16 / 25 With an increase in lip angle keeping side rake angle constant, strength of tool. Decreases Increases None of the mentioned Remains constant 17 / 25 Flank wear occurs at Tool flank below cutting edge Tool face None of the mentioned Tool shank 18 / 25 Angle between the rake face flank of tool and perpendicular line drawn from cutting point to base of tool is known as: Back rake angle Side relief angle End relief angle Side rake angle 19 / 25 Which of the following will give maximum chip flow during machining? Hard material All of the mentioned Brittle material Ductile material 20 / 25 What is the optimum value of positive rake angle in degrees for maximum tool life? 10 20 15 12 21 / 25 Crater wear occurs at Tool shank None of the mentioned Tool face Tool flank 22 / 25 Angle between side cutting edge and end cutting edge in the top surface plane of tool. Side relief angle Side rake angle Side cutting edge angle Nose angle 23 / 25 Which of the following will give large friction during chip flow? Small lip angle tool Zero back rake angle tool Negative back rake angle tool Positive back rake angle tool 24 / 25 Which of the following is correct about crater wear? None of the mentioned Occurs more in soft tool Occurs more in brittle tool Occurs more hard tool 25 / 25 If a percentage of cobalt in Tungsten carbide tool increases, then toughness of tool will Decrease Remains Constant Increase First increase then decrease Your score isThe average score is 0% LinkedIn Facebook VKontakte 0% Restart quiz Related Spread the love
