A flexible manufacturing system is a type
of industrial process that allows equipment
to be used for more than one purpose,
though they may be somewhat related.
The concept of flexible manufacturing systems
evolved during the 1960’s when robots,
programmable controllers, and computerized
numerical controls brought an environment to
the factory floor in the form of numericallycontrolled and direct-numerically-controlled
machines.
The main goal of a flexible manufacturing
system (FMS) is to offer the speed needed
to change with market conditions quickly,
but not sacrifice any quality.
Equipments of FMS
Equipment that does this most effectively is likely
designed for two or more purposes.

The potential benefits from the
implementation and utilization of a flexible
manufacturing system have been detailed
by numerous researchers on the subject.
These benefits include ;

Despite these benefits, FMS do have
certain limitations. In particular, this type
of system can only handle a relativelynarrow range of part varieties, so it must
be used for similar parts that require
similar processing.
Due to increased complexity and cost, an
FMS also requires a longer planning and
development period than traditional
manufacturing equipment.
Any system will have certain
disadvantages. The possible
disadvantages associated with the
system are as follows:


Very high start-up cost.
Problems may occur in the various
components of the systems, which may
require a long debugging process.


However, the magnitude of flexibility that
the system offers and the volume of
production completely justifies the high
initial investment made to develop this
system.
Any system of this magnitude and
complexity it bound to develop some
problems. Anyway,the returns offered by
this system completely justify the time
spent on debugging it.
Consequence


Flexible manufacturing systems are now
being widely employed to improve
productivity and quality of the product. It
also improves the quality of life for the
operator. The new techniques will have a
major impact on economic factors.
Finally, implementation of FMS will
benefit both the manufacturer and
the costumer.
