MANUFACTURING SYSTEM

MANUFACTURING SYSTEM

Manufacturing basically implies making of
goods or articles and providing services to meet the needs of mankind. It
creates value by useful application of physical and mental-labor in the
process. It is a chain of interrelated activities of production process and
other support services activities of an manufacturing environment such as order
processing, product design, design and manufacturing of tools, die, mould,
jigs, fixtures and gauges, selection of material, planning,
managing
and maintaining control
of the processes, production, and reliable quality of processed product in a
systematic and sequential manner with proper coordination, cooperation and
integration of the whole manufacturing system that will lead to economical
production and effective marketing of proposed product in the minimum possible
time. It
is, therefore, evident that
manufacturing today is not a one man activity as it was in the initial stages,
wherein all the physical and mental inputs were applied by a single craftsman.
These days it has become totally a team work which consists of several
components interacting
together in a
dynamic manner. This entire domain of
manufacturing is known as Manufacturing
System, which takes the required inputs and delivers the products for
the
customer. It is, therefore, evident that manufacturing
today is not a one man activity as it was in the preliminary stages, wherein
all the physical and mental inputs were provided by a
single workman. Today it
is a team work
which consists of
several components interacting together in
a dynamic
manner to provide
the required physical
and mental inputs
at appropriate stages to
impart desired results. This entire domain of manufacturing is known as
Manufacturing System,
which takes the required
inputs and delivers
the products for the customer.

Manufacturing system requires a
large number of activities, few independent and rests mostly
interrelated. The manufacturing activities in a manufacturing system jointly contribute towards
economic and qualitatively acceptable production of desired articles in minimum
possible
time. As per the need of
the
customer, the products are
identified and their demands are determined roughly for market forecast by
considering present and future
competition. Products
that may render the desired service over its expected life satisfactorily as
per requirement of customers are identified in terms of their demand, conceived
and developed for securing orders by the sales department. Once the product
design activity is over and
the design
finalized from all
angles, functional,
aesthetic, material selection,
safety,
economy,
etc., it is followed by preparation of production
drawings
of the product assembly and
its
components including a bill of
materials. This is the stage where a make or buy decision has to be taken in
order to decide as to which components are to be bought from outside and which
are to
     be manufactured within the concern.
It is followed by process planning i.e. selection of
the best process and an its parameters, design of jigs, fixtures
and dies, selection of tooling, programming of tool path as per need, for the
components to be produced in-house. An important
activity in process
planning within the organization is also to involve latest
research and development findings, through which the old processes are
improved and new one’s
are developed
in order to ensure better quality and economic production. 

The interaction of
different
manufacturing activities in a manufacturing system can also be further
enhanced by the use of
computer and hence leading CIM. The real manufacturing or production
activity
   is carried out on the shop.
The layout of the shop floor has a significant influence on the tools required to
be coordinated in order to an economical and high quality production of various
components. It should be such that it ensures timely movement of raw materials,
dies moulds, jigs and fixtures and finished components, adequate safety to men,
material
and machinery, enables timely inspection and quality control and
minimizes handling time
for material
and parts, etc. During actual manufacturing a lot of different activities are
called management function. Various
engineers play an important role in the organizational function of a manufacturing concern. They
are required to ensure proper movement of the material, tools
and parts as per their specialized jobs in industry.
