3. What is FMS ?
A flexible manufacturing system is a automated machine cell, consisting of a group of processing workstations, interconnected with automated material handling and storage system.

4. History of FMS
The first FMS was patented in 1965 by Theo Williamson who made numerically controlled equipment. Examples of numerically controlled equipment are like a CNC lathes or mills which is called varying types of FMS.

5. Why FMS ?
External changes such as change in product design and production system.
Optimizing the manufacturing cycle time
Reduced production costs
Overcoming internal changes like breakdowns etc.

6. Basic components of FMS

17. Flexibility in FMS
Flexibility in manufacturing means the ability to deal with slightly or greatly mixed parts, to allow variation in parts assembly and variations in process sequence, change the production volume and change the design of certain product being manufactured.

18. Continue…..
To be flexible, a manufacturing system must posses the following capabilities:
Identification of the different production units to perform the correct operation.
Quick changeover of operating instructions.
Quick changeover of physical setups of fixtures, tools and other working units.

19. Application of FMS Metal-cutting machining Metal forming Assembly
Joining-welding (arc , spot), glueing
Surface treatment
Inspection
Testing

22. Advantages of FMS To reduce set up and queue times Improve efficiency
Reduce time for product completion
Utilize human workers better
Improve product routing
Produce a variety of Items under one roof
Improve product quality
Serve a variety of vendors simultaneously
Produce more product more quickly

23. Disadvantages of FMS
Expensive.
Substantial pre-planning activity.

24. Processing of Gear 1 by Conventional Manufacturing System.

25. Processing of Gear 2 by Flexible Manufacturing System

26. The processing of Gear by FMS saves approximately 100 seconds per gear including pre & post processing adjustments. This means if number of gears to be produced increases this will save lot of time and increase productivity of the manufacturer. This will help in earning more profit. Hence FMS is more beneficial than conventional manufacturing system.

27. Comparison

28. Challenges with FMS
Determining if FMS the best production system for your company
Possible expansion costs associated with implementing FMS
These challenges must never be overlooked when deciding whether or not to implement a FMS system. In order to get the best possible results you must answer the these questions within your own firms.

29. Conclusion
FMS is a revolution in the field of Manufacturing Technology.
FMS can be designed to meet the specific demand of each company
FMS is used for multitask operation.
FMS requires substantial investment of time and resources.
