Definition
A Flexible Manufacturing System (FMS) is a production system consisting of a set of identical and/or complementary numerically controlled machine which are connected through an automated transportation system.
each process in FMS is controlled by a dedicated computer (FMS cell computer).
Equipment of FMS
Primary equipment
work centers
Universal machining centers (prismatic FMSs)
Turning centers (rotational FMSs)
Grinding machines
Nibbling machines
Process centers
Wash machines
Coordinate measuring machines
Robotic work stations
Manual workstations
FMS different approaches
The capability of producing different parts without major retooling
A measure of how fast the company converts its process/es from making an old line of products to produce a new product
The ability to change a production schedule, to modify a part, or to handle multiple parts
Disadvantage of using FMS
Limited ability to adapt to changes in product or product mix (ex:machines are of limited capacity and the tooling necessary for products, even of the same family, is not always feasible in a given FMS)
Substantial pre-planning activity
Expensive, costing millions of dollars
Technological problems of exact component positioning and precise timing necessary to process a component
Sophisticated manufacturing systems
FMS Layouts Continued
Ladder Layout:
Parts can be sent to any machine in any sequence
Parts not limited to particular part families
Open Field Layout:
Most complex FMS layout
Includes several support stations
