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