Theory Examination (Semester-II) 2015-16 BASIC MANUFACTURING PROCESS

This question paper evaluates student knowledge in workshop technology, welding, casting, metal forming, heat treatment, machine tools, and manufacturing systems.
It is divided into three sections, covering definitions, medium-length answers, sketches, and long descriptive explanations.

SECTION – A (10 × 2 = 20 Marks)

This section contains short questions requiring brief explanations.
Topics include:

Components and operations of a shaper

Difference between shaper & planer

Production vs productivity

Types of production systems

Principle of oxy-acetylene welding

Types of gas flames and their uses

Annealing & normalizing of carbon steels

Electroplating & galvanizing

Tool steels and their classification

Ductile vs brittle fracture

This section checks basic manufacturing and material science concepts.

SECTION – B (5 × 10 = 50 Marks)

Students must attempt any five descriptive questions (many require neat sketches).
Topics include:

Shaper machine: components, operations, drive mechanisms

Oxy-acetylene welding: principles, flames, identification & applications

Annealing & normalizing with diagrams

Electroplating & galvanizing (process + sketches)

Tool steels, uses of copper alloys (brass/bronze)

Construction + working + applications of cupola furnace

Die casting: process with neat sketch

Ductile casting process & advantages

Slag inclusion and how to avoid it

Application of oxidizing, neutral & carburizing flame

This section tests process understanding, sketches, material behavior, and practical workshop knowledge.

SECTION – C (2 × 15 = 30 Marks)

Students must attempt any two long-answer questions.

Topics include:

Shaper Machine (Detailed)

Working principle

Construction with sketch

Operations

Limitations and applications

Production & Manufacturing

Role of materials and manufacturing in national growth

Types of production (job, batch, mass, continuous) with examples

Cupola Furnace & Related Concepts

Full working principle with labeled diagram

Advantages, limitations & casting applications

This section evaluates deep technical understanding, diagram-based explanation, and analytical skills.
