Chapter:

26. Complex shape can be formed effectively using?

Powder metallurgy Turning Sand casting Metal casting

Powder metallurgy

Powder metallurgy allows us to create high-quality components, while near-net-shape dimensional control provides a high degree of control over manufacturing process, facilitating production of complex shapes.

Hint Answer

27. Doubling time in flat mould will increase thickness of wall skin by what percentage?

31.6% 41% 73% 22%

41%

Thickness is proportional to ? time. When time is doubled in flat mould, thickness of wall skin will increase by 41%.

Hint Answer

28. Which of following is made of wood?

Gate Riser Bottom board Chill

Bottom board

A chill is an object used to promote solidification in a specific portion of a metal casting mold. Normally metal in mold cools at a certain rate relative to thickness of casting. When geometry of molding cavity prevents directional solidification from occurring naturally, a chill can be strategically placed to promote it.

Hint Answer

29. Which of following code will change specified input values in millimeters?

G01 G00 G20 G20

G20

G20 will change specified input values in millimeters.

Hint Answer

30. Which of following code is used to specify feed per revolution in turning?

G99 G98 G78 G45

G99

G99 is used to specify feed per revolution in turning.

Hint Answer

31. Formation of metal powder to use in powder metallurgy by reducing some compound with CO or or molecules is known as?

Atomization Reduction Crushing Electrolysis

Reduction

Reduction is process of formation of metal powder to use in powder metallurgy by reducing some compound with CO or or reducing agents.

Hint Answer

32. Which following code will produce dwell for a specified time?

G18 G65 G45 G04

G04

G04 will produce dwell for a specified time.

Hint Answer

33. Which of following code is used to give cutter offset compensation, right of a part surface?

G00 G41 G42 G91

G42

G42 is used to give cutter offset compensation, right of part surface.

Hint Answer

34. The channel through which metal or plastic is poured into a mould?

Sprue Gate Flask Riser

Sprue

The passageway in parting plane through which molten flow is regulated is known as sprue. It may be used to control flow of metal in mould cavity.

Hint Answer

35. Powder of various and non-ferrous material which becomes brittle on heating, can be formed using?

Atomization Reduction Crushing Electrolysis

Crushing

Ferrous and non-ferrous metals are heated first, and when y become brittle, y are crushed. If copper is heated to red heat and cooled slowly it becomes brittle.
