Prepare Question for Fundamental Design and manufacturing

Hi Friend I give you the question from Engineering Design Process and its structure which is mostly come in AMIE Section A exam those are

(a) What is mean by engineering Design ? ( Answer link given click on question to read )

(b) What are the different stages of Engineering design? Discuss with a suitable examples.

(c) How will you integrate the functions of design and manufacturing? How it will help in achieving economic manufacturing?

(d) List out the characteristics of a good designer.

(e) What is product life cycle? Illustrate, with a suitable example, the various stages of product life cycle?

(f) Briefly describe the various product design techniques.

(g) Write a descriptive note on design checks for clarity,simplicity and safety

(h) What is the role and importance of aesthetics in design ? what are the important aesthetics design requirements? Discuss.

(i) in a system there are four components in parallel followed by three components in series. The components in parallel have a reliability of o.7 each and those in series have reliability of entire system.

Define the terms :
 Reliability
 Mean time to failure,
 Mean time between failure.

(j) explain with diagram a process for the production of seamless tube and pipes.

Question from Needs,Morphology,brainstorming,evaluation of design

(a) What do you mean by ‘standards of performance’? Enumerate the factors affecting this. Explain these factors in brief.

(b) What do you understand by specifications? At what stage these should be defined during the process of product development? Explain.

(c) Differentiate Between standardization and specification giving appropriate examples. How are “preferred number” useful in standardization? explain with the help of suitable example.

(d) Explain ‘Evaluation’ and ‘Evolution’ in the design process.

(e) With the help of an example, explain the concept of Morphology of Design.

(f) What is the role of the need analysis in the Design Process? Distinguish between need analysis and need statement.
Give one need statement for each of the following
(i) Bicycle
(ii) Washing machine
(iii) Personal Computer
(iv) Private Car

(g) Clearly explain ' Brainstorming' with respect to ideonomics.

Question from Casting Process

(a) Write down the objectives of design for manufacturing, Enumerate the points to be observed while designing for ‘Casting’ and ‘Easier Machining’?

(b) Name the sand molding methods. Describe these in brief with the help of figures. What is directional solidification?

(c) Explain permanent mould casting processes.

(d) What are main advantages of the casting process? What is its limitation and how are they overcome?

(e) Describe the investment casting process. What are the advantages and disadvantages of investment casting process ? mention some o its application.

(f) What is a sweep pattern? When is it used?

(g) Define the terms
• Sprue
• Gate
• Core
• Parting line

(h) Briefly explain the characteristics of molding sand required to have a sound mold.

(i) Define Shrinkage and Porosity in castings. How can one tell whether cavities in casting are due to porosity or shrinkage ?
How are dissolved gases removed from castings? List four casting defects.

(j) Why is ‘clearance’ provided in die and punch for blanking and piercing operations? Explain with net sketches.

(k) what are the distinguish features between a casting and pattern?

Question from Manufacturablity / Sort Notes

1. Select a product, such as the telephone or the television, and prepare sketches to describe how their appearances have changed from their inception to the present. What role has technology had in influencing these changes?

2. Explain the following:

o Rolling
o Extrusion
o Blanking
o Forging
o Considerations of design of castings
o Reliability and robust design
o Design for reliability
o Design for assembly
o Role of brain storming in design idea generation.
o Design communication
o Tools of information technology.

3. (a) Define the term reliability and maintainability. Compare the reliability of systems with components in series vs. components in parallel.

(b) What is input-output model? How will you use this model for a manufacturing process? What are the main factors on which the selection of a manufacturing process
depends ? What are the different processes that will represent the area of manufacturing?

(c) What do you understand by design for safety?

(d) What are the essential contents of a technical report? Explain briefly.

(e) Explain how the systematic design process can aid in creating quality products.

(f) What are the major classifications of basic manufacturing processes? Highlight the characteristics of each and its specific applications.

(g) How would you give the specifications for a lathe and milling machine?

4. Differentiate between the following
 Hot working and cold working
 Rolling and forging
 Extortion and wire drawing
 Blanking and piercing
 Creative Design and Innovative Design
 Discrete Manufacturing and continuous manufacturing
 Physical reliability and Economic Feasibility

5. (a) What do you mean by design communication/ How does a drawing help to a design engineer to share his ideas?

(b) During writing a technical report, what point should be kept in mind for easy communication?

(c) what factors govern the selection of manufacturing process for a product?

See the below 'post reply' answer of that above question mostly coverd
hi friend if you feel my discussion is helpful to all then please reply then only i continue my discussion.


  1. Very Surprise of all our customer give the Business Loan for any project such as all our customer wants only minimum interest and quick project funding.

  2. Majorly more type of Pipe Threading Machine Perfectly work in all type of pipe. Electric consumption is always good. But with out power we use only Boom Lift Batteries only solve the problem.

  3. Nice and more reachable blog. Kindly update about some Modular Kitchen In Chennai & Modular Kitchen in Chennai Company
