- 4. TYPES OF FMS LAYOUTS 1. Progressive or Line Type Layout • 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.
- 5. PROGRESSIVE OR LINE TYPE LAYOUT
- 6. CONT.… 2. Loop Type Layout • The parts usually move in one direction around the loop, with the capability to stop and be transferred to any station. • The loading and unloading station are typically located at one end of the loop.
- 8. 3. Ladder Type Layout • The loading and unloading station is typically located at the same end. • The sequence to the operation/transfer of parts from one machine tool to another is in the form of ladder steps. CONT.…
- 10. CONT.… 4. Open field Type Layout • The loading and unloading station is typically located at the same end. The parts will go through all the substations. • such as CNC machines, coordinate measuring machines and wash station by the help of AGV’s from one substation to another.
- 11. OPEN FIELD TYPE LAYOUT
- 12. CONT.… 5. Robot centered Type Layout • Robot centered cell is a relatively new form of flexible system in which one or more robots are used as the material handling systems. • Industrial robots can be equipped with grippers that make them well suited for handling of rotational parts.

FACTORS INFLUENCING THE FMS LAYOUTS • 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 conditions
