Maximum Marks: Answer FIVE questions, taking ANY TWO trom Group A. Excellent design and effective manufacture are the pre-requisites of a successive This problem can be solved only by designing and manufacturing better.
Identification and analysis of need, product design specifications, standards of performance and constraints. Searching for design concepts: Morphological analysis, brainstorming.
Evaluation of design concepts for physical reliability, economics, feasibility and utility. Detailed design:Design for manufacture, assembly, shipping maintenance, use, and recyclability.
The 5 Types of Manufacturing Processes
Design checks for clarity: Simplicity modularity and safety. Standardization and size ranges.
Reliability and robust design. Design organization and communication technical reports, drawings, presentations and models. Concept of manufacturing: Classification of manufacturing processes.
Most companies use more than one of these environments to get a single product out the door. This is certainly true considering today's use of the supply base versus the historical practices of vertically integrated companies.
Vertically integrated companies often had all five environments. Speeding up or slowing down the speed of the operation modulates differences in customer demand. There is little setup and changeover activity. If the peak line speed cannot keep up with demand, a second line is added.
If demand is not enough for a dedicated second line, it is met by a second line operating in Discrete mode that also makes other products. Discrete: This environment is highly diverse. It covers a range from few setups and changeovers to frequent setups and changeovers.

The products being made may be alike or highly disparate. The more unlike the products are, the longer is the unproductive set-up and tear-down time. Job Shop: Job shops rarely have production lines, they have production areas. The area may assemble only one version of a product, a dozen versions, or even a couple dozen. CAD systems function by their capacity to codify geometrical concepts.
Thus the design process using CAD involves transferring a designer's idea into a formal geometrical model. Efforts to develop computer-based "artificial intelligence" AI have not yet succeeded in penetrating beyond the mechanical—represented by geometrical rule-based modeling.
Other limitations to CAD are being addressed by research and development in the field of expert systems.
THE ORIGINS OF CAD/CAM
This field is derived from research done in AI. One example of an expert system involves incorporating information about the nature of materials—their weight, tensile strength, flexibility, and so on—into CAD software. By including this and other information, the CAD system could then "know" what an expert engineer knows when that engineer creates a design.
The system could then mimic the engineer's thought pattern and actually "create" more of the design. Expert systems might involve the implementation of more abstract principles, such as the nature of gravity and friction, or the function and relation of commonly used parts, such as levers or nuts and bolts.
Such futuristic concepts, however, are all highly dependent on our abilities to analyze human decision processes and to translate these into mechanical equivalents if possible. One of the key areas of development in CAD technologies is the simulation of performance.
Among the most common types of simulation are testing for response to stress and modeling the process by which a part might be manufactured or the dynamic relationships among a system of parts. In stress tests, model surfaces are shown by a grid or mesh, that distort as the part comes under simulated physical or thermal stress. Dynamics tests function as a complement or substitute for building working prototypes. The ease with which a part's specifications can be changed facilitates the development of optimal dynamic efficiencies, both as regards the functioning of a system of parts and the manufacture of any given part.
Simulation is also used in electronic design automation, in which simulated flow of current through a circuit enables the rapid testing of various component configurations.
The processes of design and manufacture are, in some sense, conceptually separable.True [S '97] 2. This is the phase that takes into account when the product has reached the end of useful life.
A quality control specialist observes how well the product meets specifications.

The manufacturing department interprets that design and makes the product according to what they think suitable. In this method each functional departments were separated from others, as shown by wall.
He has to ensure the technical and economical feasibility of the product. Design process and explain W'96 Justify the statement with reasons Modern design problems cannot be handled by traditional methods'.
A plan shows how a project will be initiated, organized, co-coordinated and monitored. They must also be expert in understanding how their design can be manually assembled.
