THEORY EXAMINATION (SEM–II) 2016-17 MANUFACTURING PROCESS

This question paper evaluates the student's understanding of metalworking processes, welding, casting, machining, material properties, layouts, and manufacturing fundamentals.
It is divided into three sections covering definitions, comparisons, process explanations, and short descriptive notes.

SECTION – A (10 × 2 = 20 Marks)

This section contains ten short questions, each requiring direct answers.
Topics include:

Electrochemical coating processes (electroplating, anodizing)

Operations of a lathe machine

Aluminum alloys with compositions

Gang milling

Materials welded by neutral flame

Examples of fixed-position layout

Type of loading causing fatigue failure

Recrystallization

Function of riser in casting

Product of a cupola furnace

This section checks basic manufacturing knowledge and key terminologies.

SECTION – B (5 × 10 = 50 Marks)

Students must attempt any five descriptive questions.
Topics include:

Shaper vs planer; shaping machine drive mechanisms with sketch

Formation of arc in welding; welding power sources, advantages & limitations

Comparison: hardness vs toughness; strength vs stiffness

Hot working vs cold working with examples, advantages, and disadvantages

Types of patterns, pattern allowances, and pattern–casting differences

Properties of metal powders and applications of powder metallurgy

Ductile vs brittle fracture; meaning of creep and creep curve

This section tests understanding of processes, characteristics of materials, and practical workshop knowledge.

SECTION – C (2 × 15 = 30 Marks)

Students must attempt any two long-answer questions.

Milling Operations

Difference between up-milling and down-milling

Various work-holding devices in milling, their applications & limitations

Short Notes

High-speed steel (HSS): properties & applications

Moulding sand properties

Deep drawing operation

Composite materials

Production Concepts

Difference between production and productivity

Product layout vs process layout with examples

This section evaluates analytical ability, comparative understanding, and descriptive skills.
