Introduction to Flexible Manufacturing System (FMS)
• A flexible manufacturing system (FMS) is a highly automated
Group Technology machine cell, consisting of a group or
processing workstations (usually CNC machine tools),
interconnected by an automated material handling and
storage system, and controlled by a distributed computer
system.
• The reason the FMS is called flexible is that it is capable of
processing a variety of different part styles simultaneously
at the various workstations, and the mix of part styles and
quantities of production can be adjusted in response to
changing demand patterns.

The FMS is most suited for the mid-variety, mid-volume
production range.

Components of FMS
• There are several basic components of an FMS:
1. Workstations.
2. Material handling and storage systems.
3. Computer control system.
4. People are required to manage and operate the
system.
27/08/2015akhtar kamal 6
1.Workstations
• Following are the types of workstations typically
found in an FMS:
1. Load/Unload Stations.
2. Machining Stations.
3. Other processing Stations. (punching, shearing,
welding, etc.)
4. Assembly Station.
5. Other Stations and Equipment. (Inspection, Vision,
etc)
27/08/2015akhtar kamal 7
2.Material Handling and Storage System
• Functions of the Handling System
1. Independent movement of work parts between stations.
2. Handle a variety of work part configurations.
3. Temporary storage.
4. Convenient access for loading and unloading work parts.
5. Compatible with computer control.

3.Computer Control System
• The FMS includes a distributed computer system that is
interfaced to …
 the workstations,
 Material handling system, and
 Other hardware components.
• Human are needed to manage the operations of the FMS.
Functions typically performed by human includes:-
 Loading raw work parts into the system,
 Unloading finished parts (or assemblies) from the system,
 Changing and setting tools,
 Equipment maintenance and repair,
 NC part programming in a machining system, and
 Programming and operation the computer system.

Flexible Manufacturing Cell (FMC)
• A flexible manufacturing cell consists of two or three processing workstations
(typically CNC machining centers) plus a material handling system.
• The material handling system is connected to a load/unload station.

Advantages of flexible manufacturing
systems
1. Increased machine utilization
2.Lesser number of machines required
3.Reduction in floor space requirement
4. Greater flexibility
5.Reduction in inventory
6. Lower manufacturing lead time
7.Reduced labor requirement
8. Better product quality and productivity
9. Extended period production
27/08/2015akhtar kamal 18
Limitation of flexible manufacturing
systems
1. High initial cost
2. High maintenance cost
3. Worker unemployment
27/08/2015akhtar kamal 19
Application of flexible manufacturing
systems
• The four types of production systems can be distinguished in
terms of production quality (volume) and product variety
(flexibility),as shown in Figure
• The stand alone machines including CNC machines are highly
flexible and most suited for large product varieties. However, they
are not suitable for large production quantity.
