Chapter:

16. Which of following tool will give best result for machining of brass?

Large positive rake angle tools Large negative rake angle tools Zero rake angle tools Small point angle tools

Zero rake angle tools

Brass is neir very hard nor very soft and zero rake angle tool would be best option for machining of brass.

Hint Answer

17. For large negative back rake angle, tool will be

Weaker Stronger Smoother Harder

Stronger

With an increase in negative back rake angle, lip angle increases and tool tip become thick and hence strength of tool will increase.

Hint Answer

18. Which of following tool material will offer lower friction and higher resistance to cracks and wear?

HSS TiC WC TiCN

TiCN

TiCN is a coated tool and hence offer very less friction and re is much low chance of wear in tool due to coating on tool.

Hint Answer

19. Angle between rake face flank of tool and perpendicular line drawn from cutting point to base of tool is known as:

Side rake angle Side relief angle End relief angle Back rake angle

Side relief angle

Side relief angle is angle between flank of tool and perpendicular line drawn from cutting point to base of tool.
