2. Conventional Manufacturing Consisted of 2 varieties
Job Shop type systems were capable of large variety of product, but at a high cost.
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.
3. 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.
4. What is CIM? CIM is the integration of the total manufacturing enterprise through the use of integrated systems and data communications coupled with new managerial philosophies that improve organizational and personal efficiency.
5. 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.

8. Manufacturing Cells VS FMS A FMS/FAS is a manufacturing cell, but a cell is not necessarily a FMS/FAS
A FMS/FAS is a complete system that runs automatically
A manufacturing cell has some or most of the components of a FMS/FAS, but not all of them.
9. History of FMS 1950’s NC machines first appear
1960’s Computers appear in industry
Later 1960’s Flexible Manufacturing Systems first appeared in the U.S.A. at companies like Ingersoll-Rand, Caterpillar, John Deere, and General Electric Co.

17. Computer Controls (cont) Tool control
Tool life monitoring
Performance monitoring and reporting
18. 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
19. Why Implement a FMS/FAS? (continued) Reduced direct labor requirements and higher labor productivity
Opportunity for unattended production
20. FMS Implementation Issues Part family considerations
Physical characteristics or workparts
Scheduling and dispatching
21. FMS Issues (cont) Part grouping
Pallet and fixture allocation
Requires management commitment and planning
Major invest of time and money
