A Flexible Manufacturing System

1. A Flexible Manufacturing System (FMS) is the current level of automation in the field of manufacturing. The application of FMS requires advanced technical know-how.

A Flexible Manufacturing System may be defined as a system dealing with high level

distributed data processing and automated material flow using computer-controlled

machines, cells, industrial robots, inspection machines and so on, together with computer

integrated materials handling and storage systems.

Here manufacturing is considered to be a system which integrates different processes and

requires a properly defined input to create the expected output.

2. Input may be raw material and/or data which have to be processed using various auxiliary components of the system, such as tools, fixtures and clamping devices, sensors and their feedback data. The output may also be data and/or material which can be processed on further units (often called cells) of the manufacturing system.

3. An FMS can also be defined as a computer-controlled configuration of semi-independent

work stations and a material handling system designed to efficiently manufacture more than one kind of part number at low to medium volumes. The definition highlights the three essential physical components of an FMS:

a) standard numerically controlled machine tools;

b) a conveyance network to move parts and perhaps tools between machines and

fixturing stations;

c) an overall control system that coordinates the machine tools, the parts and the work

pieces.

The number of machines in a system typically ranges from 2 to 20 or more. The

conveyance system may consist of carousels, conveyors, carts, robots, automated guided

vehicles, etc.

4. The FMS can be thought of as a distributed management information system linking together intelligent subsystems of machining, welding, painting, flame cutting, sheet metal manufacturing, inspection, assembly, etc. and material handling and storage processes.

Flexible manufacturing systems are regarded by many experts as being the best way to

meet the demands of industry. They consider the FMS to be the future of the automated

factory, or at least the minimally manned factory. And perhaps most significant that

FMS is clearly the most obvious manifestation of computer-inte­grated manufacturing on

the factory floor.

5. So it is possible to say that the FMS is of interest to manufacturers who produce more than one kind of part number at low to medium volumes. The FMSs provide a direct hardware/software solution to many economical and technical problems. The important aspect of these systems is that the machine tools, conveyance and control devices combine to achieve increased productivity and maximum machine utilization without decreasing flexibility.
