2. Introduction to FMS History of FMS Why FMS ? Basic components of FMS FMS equipment Types of FMS Layouts of FMS Flexibility in FMS Applications of FMS Advantages Disadvantage Challenges with FMS Conclusion References CONTENTS

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

4. 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. History of FMS

5. 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. Why FMS ?

6. Workstations Automated Material Handling and Storage systems Computer Control System Basic components of FMS

7. Substations 1. Load/Unload Stations 2. Machining Stations 3. Other processing stations 4. Assembly Workstation

8. AGV Material handling system

9. Computer control Programmable logic Controller

16. 5. Robot Centered Layout

17. 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. Flexibility in FMS

18. 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. Continue…..

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

20. FMS at Vought Aircraft

21. 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 Advantages of FMS

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

23. Processing of Gear 1 by Conventional Manufacturing System.

24. Processing of Gear 2 by Flexible Manufacturing System

25. 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.

26. Comparison

27. Determining if FMS the best production system for your company Possible expansion costs associated with implementing FMS Challenges with FMS

28. 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. Conclusion
