3.  A Flexible manufacturing is a automated
machine cell ,consisting of a group of
processing workstations ,interconnected with
automated material handling and storage
system and controlled by integrated computer
control system.

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

7.  External changes such as change in product design
and production system.
 Optimizing the manufacturing cycle time.
 Reduced production costs.
 Overcoming internal changes like breakdown etc

8.  Work stations.
 Automated material handling and storage system
 Computer control system.

9.  Substation.
 Load and unload station.
 Machining station.
 Other processing station.
 Assembly.

14.  Sequential FMS.
 Random FMS.
 Dedicated FMS.
 Engineered FMS.

15.  Sequential FMS: It manufactures one piece part
batch type and planning and preparation is carried out
for the next piece part batch type to be manufactured.
 Random FMS :It manufactures any random mix of
piece part types at any one time.
 Dedicated FMS : It continually manufactures , for
extended period , the same but limited mix of piece
part batch types.
 Engineered FMS : It manufactures the same mix of
part types throughout its lifetime

16.  Progressive or Line type.
 Loop type:
 Ladder type.
 Open field type.
 Robot cantered type.

17. Progressive or Line type
 The machines and handling system are arranged in a
line.
 In this system part progress from one workstation to
the next in a well defined sequence with no back flow
 Work always flows in unidirectional path.

18. Loop type
 In this , parts usually move in one direction around
the loop, with capability to stop and be transferred to
any station.
 The loading and unloading stations are typically
located at one end of the loop.

20.  The loading and unloading stations is typically at the
same end.
 The sequence to the operation /transfer of parts from
one machine tool to another is in the form ladder
steps.

21.  The loading and unloading stations is typically at the
same end.
 The parts will go through all the substations such as
CNC machine , coordinate measuring machines and
wash station by the help of AGV’S from one
substation to another.

23.  Robot cantered cell is a relatively new form of
flexible system.
 One or more robots are used as the material handling
system.
 Industrial robots can be equipped with grippers that
make well suited for handling of rotational parts

25.  Availability of raw material.
 Proximity to market.
 Transport facilities.
 Availability of efficient and cheap labour.
 Availability of power, water and fuel.
 Atmospheric and climatic condition.
 Social and recreation facilities.
 Business and economic condition.

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

27.  To be flexible , a manufacturing system must posses
the fallowing capabilities.
 Identification of the different production units to
perform the correct operation.
 Quick changeover of operation instruction.
 Quick changeover of physical setups of fixtures ,
tools and other working units.

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

31.  To reduce setup and queue times.
 Improve efficiency.
 Reduce time for product completion.
 Utilize human worker better.
 Improve product routing.
 Produce variety of items under one roof.
 Improve product quality.
 Serve a variety of vendors simultaneously.
 Produce more product more quickly.

32.  Limited ability to adapt to changes in product or
product mix.
 Expensive
 Substantial pre-planning activity.
 Sophisticated manufacturing system.

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

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

38.  FMS is a revolution in the field of manufacturing technology
and
 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.
 AGV’s and AS/RS is a great system which was developed to
improve the material handling and storage systems used in
industries to handle, store and retrieve materials with
precisions, accuracy and speed under defined degree of
automation.
