PRODUCT DEVELOPMENT: Product functions


A product development has to go through the
following concepts of product engineering which are given as under.

Product functions: 

1. Product specifications

2. Conceptual design

3. Ergonomics

4. Standards

5. Detailed design

6. Prototype development

7. Testing, Simulation

8. Design

9. Design

10. Drafting.

Now let us consider the manufacturing
environment of a given product. How does the product idea originate. Market
forces determine the need for a product. Expertise on the part 
of the company
estimates the likely demand and probable profitability and decides on the best mode
of designing and manufacturing the desired product.

after the design of the product,
the part prints are released for production. The production engineering section
first considers the feasibility of production of the product. Having
ascertained its feasibility, process planning is done so that the product can
be manufactured at the lowest possible cost. Any redesign that is needed for
improving the producibility of the
product without compromising on its functionality would have to be done at this
stage. Having decided on the process plan for manufacture, the necessary
actions are undertaken for its
implementation. These are making of the tooling required, acquiring of new equipment or tools, procurement of the raw materials, releasing
of the detailed operational
instructions to the shop floor, etc. The conventional methods of
manufacturing are generally inefficient and dependent on operator skills. These
methods consume more time, have high costs,
and give poor accuracy.

Product design is an activity
which needs to be well organized and take into account
all influences that are likely to be responsible for the success
of the product under
development. A
product here means a single component which is functional in itself like a
wrench or an assembly of a large number of components all of which will
contribute to the functioning of the
part such as an automobile engine.
The complexity of the design
process certainly increases with the number and diversity
of components present in the final part. Since there are such
  a large number of influencing factors, it is
impossible to specify a design procedure for each component. Here we are
interested in developing some common guidelines and steps that
are needed
to proceed for a successful product design and manufacture.

the above discussion it can inferred that products can be manufactured by more
than one processes. Therefore several alternatives for manufacturing products
are available. The selection of a suitable
process is depended
upon the factors
including volume of production,
properties of the components, technical viability of process, economy involved
and desired quality. Based upon the
volume of product the manufacturing activity can be identified in terms of job shop production, batch production and mass production
