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 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 End relief angle Side rake angle Side relief angle 2 / 25 Angle between the rake face and plane perpendicular to rake face is known as: Side relief angle Side rake angle End relief angle Back rake angle 3 / 25 Which of the following will give maximum chip flow during machining? Brittle material Ductile material Hard material All of the mentioned 4 / 25 For machining of carbide material which of the following tool will be preferred? Large negative rake angle tools Zero rake angle tools Small point angle tools Large positive rake angle tools 5 / 25 For large negative back rake angle, tool will be Weaker Smoother Stronger Harder 6 / 25 Which of the following will give large friction during chip flow? Positive back rake angle tool Small lip angle tool Negative back rake angle tool Zero back rake angle tool 7 / 25 Angle between end cutting edge and axis of tool is known as: Side relief angle Side rake angle End cutting edge angle Back rake angle 8 / 25 With an increase in side cutting edge angle keeping width of cut constant, depth of cut will Increase Decrease Remains constant First increase then decrease 9 / 25 What is the optimum value of positive rake angle in degrees for maximum tool life? 12 10 20 15 10 / 25 Positive rake angle is given for machining of: None of the mentioned Brittle material Both hard and soft material Ductile material 11 / 25 Which of the following material can be used for coating on tools?
