Theory Examination (Semester-II) 2015-16 MANUFACTURING PRACTICES

This is a 3-hour Theory Examination for Workshop Technology / Manufacturing Processes (ME-202) with a total of 100 marks. The question paper is divided into three sections – A, B, and C, and students must answer questions from each section as directed. The paper covers core workshop practices such as carpentry, fitting, forging, molding, metal cutting, sheet metal work, welding, and machine tools.

Section – A (20 Marks)

Section A contains 10 short-answer questions, each carrying 2 marks. Students must answer all questions briefly.
These questions test basic definitions and fundamental workshop concepts, such as:

types of carpentry joints and carpentry processes

definition of fitting and fitting operations

forging defects

properties of molding sand

straight polarity vs reverse polarity

meaning of machine tools

cutting speed and feed in metal cutting

metals used in sheet metal work

materials used for patterns in foundry

This section checks quick recall and understanding of basic workshop practices.

Section – B (50 Marks)

Section B contains 8 descriptive questions, out of which any five must be attempted.
These questions require explanations, diagrams, sketches, and detailed descriptions. Topics include:

types of wood, wood properties, and carpentry tools

tools used in fitting

furnaces used in forging

principle of resistance welding, differences between spot and seam welding

sheet metal operations with sketches

working principles of shaper and milling machine

principal parts and operations of a lathe machine

pattern allowances with neat diagrams

This section tests the student's ability to explain processes clearly and draw workshop tools or machine components accurately.

Section – C (30 Marks)

Section C contains three long-answer questions, of which any two must be answered.
These involve deeper explanations, detailed notes, and sketches. Topics include:

metallurgy of weld, types of cutting tools, and molding processes

seasoning of wood and methods of seasoning

definition of forging and various forging operations with sketches

This section checks advanced understanding and the ability to present detailed technical content.

Overall Summary

This question paper evaluates the student's knowledge of practical manufacturing processes, common workshop tools, welding, foundry work, woodworking, forming operations, and machine tools.

Section A tests basic concepts

Section B checks explanations and diagrams

Section C tests detailed understanding and long descriptive answers
