Short note on BASIC CONCEPT OF WELDING

In today's world the importance of welding spread over a range,in most of the modern fabrication works welding science has numerous applications in different forms, covering a fairly wide range of such work.

Welding is an alternative method for casting or forging and as a replacement for bolted and riveted

Why we do machining ? What are the basic machining process ?

Machining is very important process in manufacturing. It is used due to following res ion :

• to make surface finishing
• to bring correct shape and size
• to provide threads and whole
• to cut the materials
• to produce seamless tube

List of last ten years question for Group a of Fundamental design and Manufacturing

hi friend here I give you List of last ten years question for Group a of

Fundamental design and Manufacturing. Go through this question and prepare yourself with those. I think it will bring at least 30 marks out of 40 from Group a of Fundamental design and Manufacturing . Please add extra question you feel which is important and out of this list . It will help all........

FUNDAMENTAL DESIGN AND ENGINEERING QUESTIONS

What are the difference between Hot Working and cold working?

Please find bellow the defferane between Hot Working and cold working of Manufacturing

SL	HOT WORKING	COLD WORKING
1	Working temperature is above the re crystallization temperature. Therefore, it can be regarded as a simultaneous process of deformation and recovery.	Cold working temperature is below the crystallization temperature.So no appreciable recovery can take place during deformation.

Is investment casting economical than other casting process?

The investment casting is economical than other casting processes due to the following reasons

– Parts of great complexity and intricacy can be cast

– Close dimensional control and good surface finish

What does you mean by casting process? and why we use casting?

Casting is a manufacturing process by which a liquid material is usually poured into a mold, which contains a hollow cavity of the desired shape, and then allowed to solidify. The solidified part is also known as a casting, which is ejected or broken out of the mold to complete the process. Casting materials are usually metals or various cold setting materials that cure after mixing two or more components together; examples are epoxy, concrete, plaster and clay. Casting is most often used for making complex shapes that would be otherwise difficult or uneconomical to make by other methods.

Short note on Modularity of design

MODULARITY

It is architecture of product which gives different model of product on different cost. Means customer can buys the product as per his budget and need. It can defined as 

”the property of functional flexibility built into the product by assembling discrete unites which can be joined to or arranged with other parts or modules”.

What does you mean for design for safety and what are the necessary step you take for that?

To provide safety of user while using the product is responsibility of designer. If any accident has occurred while using the product the user may demand the compensation, because it is also mention our constitution. Compensation varies country to country. Many times we have seen about compensation which is announced by railway administration for injured person in trains accident. Because responsibility to safety in train journey is of railway railway administration and this accident occurs due to failure railway system. This is also valid for products or building etc. It means designer will stop to design the product or any other? NO. They will design but with considering design for safety which will reduce the responsibility. Thus we can say that design for safety is tool of reducing the responsibility of designer. Following points should always be kept in mind at the time of designing or manufacturing.

What is a significance of feasibility study and Write 5 differences between Evolution and innovative design ?

A design projects begins with the feasibility study. The purpose of this phase is to achieve a set of useful solutions to the design problem. Sometimes, a design group is assigned to a project for which a design concept has already been fixed. In this case, the first step in the study process is to demonstrate whether there is an original need, which was presumed to be valid, thus indeed have current existence, or strong evidence of latest existence.  The next step is to explore the design problem and to identify its elements such as, parameters, constraints and major design criteria. In the next step, an effort is made to conceive a number of possible solutions.

How does need analysis help to build a good product design? Explain with example

Suppose we have to manufacture a mobile and following are the customer needs, we have got after primary identification of need :- 

• seamless communication 
• sms 
• videos 
• recording videos as well voice 

video lecture on engineering design process

Hi all of you online watch our video lecture on engineering design process by our team of online coaching class for amie. In this video lecture you can find the discussion on

What is an engineering Design?

What is an Engineering Design Process?

Explain with an example.

See the video lecture on engineering design process 

Design and Manufacturing (AD 301)) • Purpose of process planning

Process planning deals with the selection of the processes and the determination of conditions of

the processes. The selected operations and conditions have to be realized in order to transform raw material into a given shape. All the specifications and conditions of operations are included in the process plan. The process plan is a document such as engineering drawing. Both the engineering drawing and the process plan present the basic document for the manufacturing of products.

Process planning meaningly influences time to market and productions cost. Therefore the planning activities have a great meaning for competitive advantage

Design and Manufacturing (AD 301)) • Type / Mathode of CAPP

Computer Aided Process Plan system is used to automate the process of production. The main two

approaches for creation and processing of process plan based on computer support and advanced planning methods. The first approach is based on Group technology utilizing (variant method), the second approach is the exact mathematical principle based on modelling of part, manufacturing knowledge and process plan (generative method).

In CAPP two different ways of obtaining the process plan can be observed:

Design and Manufacturing (AD 301)) • Important Question for Group B FDM : CAPP

Hi friend i want to guide you in real manner that is why i think when we start prepearing any subject like Fundamental design and manufacturing ( FDM ) atfirst you have to know what are the question may come in exam chapter-wise. so i start with CAPP because it is easy to learn also remember . Find bellow the question

What is a CAPP ? also describe its type .

Design and Manufacturing (AD 301)) • How CAPP is superior to manual process plan

The uses of computers in process plan have following advantages over manual experience-based process
planning :

(i) It can systematically produce accurate and consistent process plans.

(ii) It leads to the reduction of cost and lead times of process plan.

(iii) Skill requirement of process planer are reduced to develop feasible process plan.

(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?

Start preparation with Fundamental Design and Manufacturing

Hi friend I am try to Start this topic as a online coaching for all amie student who are fight to

clear there subject with there own busy schedule and i want active participation of all. First we are start with Fundamental Design and manufacturing AD301.

Now Question is How to Pass the Subject ?

You have to attain Group A (2 Question), Group b (2 question).

Start with Group A It is a much easier than Group B . Mind in Fdm not carry the mark like other subject very deicult to get good score so for passing you have
