Fms layouts and machines

1. Conventional Manufacturing
Consisted of 2 varieties
1. Job Shop type systems were capable of
large variety of product, but at a high
cost.
2. Transfer lines could produce large
volumes of a product at a reasonable
cost, but were limited to the production
of one, two, or very few different parts.

2. What is FMS/FAS?
 A FMS/FAS is one manufacturing
machine, or multiple machines that are
integrated by an automated material
handling system, whose operation is
managed by a computerized control
system. An FMS can be reconfigured
by computer control to manufacture
various products.

3. What is a manufacturing Cell?
 A manufacturing cell usually consists of two
or three processing workstations (typically
CNC Machining or turning centers) plus a part
handling system.
The following two slides contain a CAD layout
and picture of the RIT Mfg Eng Tech Class of
2000’s manufacturing work cell.

5. Flexibility in a FMS/FAS
 Machine flexibility
 Production flexibility
 Mix flexibility
 Product flexibility
 Routing flexibility
 Volume flexibility
 Expansion flexibility

6. Components of an FMS/FAS
 Workstations
 Material handling and storage system
 Computer control system
 People to manage and operate the
system

7. Types of Workstations
 Load/unload Stations
 Machining Stations
 Other Processing Stations
 Assembly
 Other Stations and Equipment (like
Inspection)

8. Layout Configurations for Material
Handling System
 In-line layout
 In-line Transfer
 Conveyor
 Rail guided vehicle
 Loop layout
 Conveyor system
 In-Floor towline carts

9. Layouts Continued
 Ladder layout
 Conveyor System
 Automated Guided Vehicle (AGV)
 Rail guided Vehicle
 Open field layout
 AGV
 In-line towline carts
 Robot-centered layout

10. Computer Control Systems
 Workstation
 Distribution of control instructions to
workstations
 Production control
 Traffic control
 Shuttle control
 Workpiece monitoring

11. Computer Controls (cont)
 Tool control
 Tool locations
 Tool life monitoring
 Performance monitoring and reporting
 Diagnostics

12. Why Implement a FMS/FAS?
 Increased machine utilization
 Fewer machines required
 Reduction in factory floor space
required
 Greater responsiveness to change
 Reduced inventory requirements
 Lower manufacturing lead times

13. Why Implement a FMS/FAS?
(continued)
 Reduced direct labor requirements and
higher labor productivity
 Opportunity for unattended production

14. FMS Implementation Issues
 Part family considerations
 Processing requirements
 Physical characteristics or workparts
 Production volume
 Scheduling and dispatching
 Machine loading
 Part routing

15. FMS Issues (cont)
 Part grouping
 Tool management
 Pallet and fixture allocation
 Requires management commitment and
planning
 Major invest of time and money
