This document provides an overview of flexible manufacturing systems (FMS). It defines FMS as an automated machine cell consisting of interconnected processing workstations and automated material handling. It discusses the history and purpose of FMS in optimizing manufacturing cycle times and reducing costs. The basic components of FMS are described as workstations, automated material handling systems, and computer control systems. The document outlines different types of FMS layouts and how flexibility is achieved. It provides examples of FMS applications and discusses the advantages of FMS in improving efficiency and reducing production time, while also noting the high expenses associated with implementation.

3.  A flexible manufacturing
system is a automated
machine cell, consisting
of a group of processing
workstations, interconnect
ed 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.

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.

6.  Workstations
 Automated Material Handling and Storage systems
 Computer Control System

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

8.  AGV

12.  Sequential FMS
 Random FMS
 Dedicated FMS
 Engineered FMS

13.  Progressive or Line Type
 Loop Type
 Ladder Type
 Open field type
 Robot centered type

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.

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.

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

22.  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.  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.

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

29.  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.
