21. • The machines and handling system are arranged in a line.
• It is most appropriate for a system in which the part progress from one
workstation to the next in a well defined sequence with no back flow.
• The operation of this type of system is very similar to transfer type.
• Work always flows in unidirectional path as shown in Figure.

22. • The parts move in one direction around the loop, with the capability to stop
and be transferred to any station.
• The loading and unloading stations are located at one end of the loop.
• One direction flow, but variations in processing sequence possible for different
part types.
• Secondary handling system at each workstation.
• Parts can skip stations for flexibility.
• Used for large part sizes.
• Best for long process times.

23. • In this configuration, part loading and unloading
stations are located at the same end.
• The sequence of the operation/transfer of parts
from one machine tool to another is in the form
of ladder steps.
• Loop with rungs to allow greater variation in
processing sequence.
• Parts can be sent to any machine in any
sequence
• Parts not limited to particular part families

24. • The open field layout is an adoption of
the loop configuration.
• The open field layout consists of loops
and ladders organized to achieve the
desired processing requirements.
• This is used for the processing of a large
family of parts.
• The number of different machines may
be limited, and the parts are routed to
different workstations depending on
availability of machines.
• A possible arrangement of this layout is
shown in fig.

25. • If a handling robot is used in a Flexible
manufacturing system cell , the machines
are laid out in a circle, such a layout is
called circular layout.
• A possible arrangement of this layout is
shown in fig.

28. • Less waste
• Fewer workstations
• Quicker changes of tools, dies, and stamping machinery
• Reduced downtime
• Better control over quality
• Reduced labor
• More efficient use of machinery
• Work-in-process inventory reduced
• Increased capacity
• Increased production flexibility
