Product Cycle Model ME6501 Computer Aided Design Notes:

Step 1: Conceive Imagine, Specify, Plan, Innovate The first step is the definition of the product requirements based on company, market and customer.

From this requirement, the product’s technical data can be defined. In parallel, the early concept design work is performed defining the product with its main functional features.

Various media are utilized for these processes, from paper and pencil to clay mock-up to 3D Computer Aided Industrial Design.

(ME6501 Computer Aided Design Notes)

Step 2: Design Describe, Define, Develop, Test, Analyze and Validate
This is where the completed design and development of the product begins, succeeding to prototype testing, through pilot release to final product. It can also involve redesign and ramp for improvement to existing products as well as planned obsolescence.

The main tool used for design and development is CAD. This can be simple 2D drawing / drafting or 3D parametric feature based solid/surface modeling.

This step covers many engineering disciplines including: electronic, electrical, mechanical, and civil. Besides the actual making of geometry there is the analysis of the components and assemblies.

Optimization, Validation and Simulation activities are carried out using Computer Aided Engineering (CAE) software.

(ME6501 Computer Aided Design Notes)

These are used to perform various tasks such as: Computational Fluid Dynamics (CFD);Finite Element Analysis (FEA); and Mechanical Event Simulation (MES).

Computer Aided Quality (CAQ) is used for activities such as Dimensional tolerance analysis.

One more task carried out at this step is the sourcing of bought out components with the aid of procurement process.

The commutation process which takes place by the action of an external force is
called forced commutation.

8. What is a chopper?
A chopper is essentially an electronic switch that turns on the fixed-voltage dc source for a short time intervals and applies the source potential to motor terminals in series of pulses.

(EE6351 ELECTRICAL DRIVES AND CONTROL Important questions)

A full converter is a tow quadrant converter in which the voltage polarity of the
output can reverse, but the current remains unidirectional because of unidirectional thyristors.

5. What is a full converter?
Free wheeling diode is connected across the motor terminal to allow for the
dissipation of energy stored in motor inductance and to provide for continuity of motor current when the thyristors are blocked. Phase control converters are used in the speed control of fractional kW dc motors as well as in large motors employed in variable speed reversing drives for rolling mills. with
motors ratings as large as several MW‟s.

Drives are employed for systems that require motion control – e.g. transportation
system, fans, robots, pumps, machine tools, etc.

Prime movers are required in drive systems to provide the sources: diesel engines, petrol engines, hydraulic motors, electric motors etc. movement or motion and energy that is used to provide the motion can come from various

Drives that use electric motors as the prime movers are known as electrical drives. There are several advantages of electrical drives: a. Flexible control characteristic – This is particularly true when power electronic Converters are employed where the dynamic and steady state characteristics of the motor can be controlled by controlling the applied voltage or current. b. Available in wide range of speed, torque and power c. High efficiency, lower noise, low maintenance requirements and cleaner operation d. Electric energy is easy to be transported.

Virtually nothing moves, turns, rolls, or flies without the benefit of cast metal products.

The metal casting industry plays a key role in all the major sectors of our economy.

There are castings in locomotives, cars trucks, aircraft, office buildings, factories, schools, and homes.

Metal Casting is one of the oldest materials shaping methods known. Casting means pouring molten metal into a mold with a cavity of the shape to be made, and allowing it to solidify. When solidified, the desired metal object is taken out from the mold either by breaking the mold or taking the mold apart. The solidified object is called the casting.
