CONTENTS
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 ?
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
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 ?
Workstations Automated Material Handling and Storage systems Computer Control System
Basic components of FMS

Types of FMS
Progressive or Line Type Loop Type Ladder Type Open field type Robot centered type
Layouts of FMS
1.Progressive Layout
2. Loop Layout
3.Ladder Type Layout 4.Open Field Layout
5. Robot Centered Layout
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
• 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.

Metal-cutting machining Metal forming Assembly Joining-welding (arc , spot), glueing Surface treatment Inspection Testing
Application of FMS
FMS at Vought Aircraft
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
Expensive. Substantial pre-planning activity.
Disadvantages of FMS
Processing of Gear 1 by Conventional Manufacturing System.
Processing of Gear 2 by Flexible Manufacturing System
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.
Comparison
Determining if FMS the best production system for your company
Possible expansion costs associated with implementing FMS
Challenges with FMS
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.
