A Flexible Manufacturing System (FMS) is an integrated production system known for its ability to readily adapt to changes in the type and quantity of the products being manufactured. This flexibility is achieved through the use of interconnected machines, automated material handling systems, and sophisticated control technologies.
Components of a Flexible Manufacturing System
An FMS typically consists of several key elements:
Workstations
Workstations are the different points in the manufacturing process where specific tasks are performed. These could be CNC machines, robotics, or other automated systems.
Material Handling Systems
Automated Guided Vehicles (AGVs) or conveyor systems are commonly used to transport materials between workstations.
Central Control System
A centralized computer or controller manages the operations of the FMS, ensuring the coordination and execution of manufacturing tasks.
Storage Systems
Inventory management systems store raw materials, work-in-progress, and finished products, facilitating the smooth flow of materials within the system.
How Does a Flexible Manufacturing System Work?
FMS operates based on a central control system that collaborates with individual workstations and material handling units. Here is a step-by-step overview:
- Instructions Input: The central control system receives production instructions regarding the type and quantity of products to be manufactured.
- Task Allocation: The control system allocates tasks to various workstations based on the current production demands.
- Material Transportation: Automated material handling systems transport materials to the appropriate workstations.
- Manufacturing Process: Workstations execute their respective tasks, such as machining, assembly, or inspection.
- Feedback Loop: Sensors and monitoring devices provide real-time feedback to the central control system to ensure operations are carried out smoothly and efficiently.
Types of Flexible Manufacturing Systems
FMS can be classified into several types based on their flexibility and configuration:
Dedicated FMS
Designed for a specific, limited range of products, dedicated FMS systems are optimized for high efficiency and lower variability in production.
Random FMS
Capable of handling a diverse range of products, random FMS systems are highly adaptable and suitable for environments with fluctuating production needs.
Special Considerations
- Initial Investment: Implementing an FMS requires significant capital expenditure, although it can lead to cost savings in the long run.
- Training and Expertise: Operators need extensive training to manage and maintain an FMS.
- Maintenance: Regular maintenance is crucial to ensuring the reliability and efficiency of the system.
Examples and Applications
Automotive Industry
FMS is widely used in the automotive sector to manage the production of various car models on a single assembly line.
Electronics Manufacturing
The electronics industry employs FMS for the flexible production of components and devices, accommodating fast-changing technology trends.
Historical Context and Evolution
The concept of flexible manufacturing emerged in the 1960s and 1970s through advances in automation and computer technologies. The integration of computer numerical control (CNC) machines and automated material handling systems marked significant milestones in the development of FMS.
Comparisons and Related Terms
Fixed Automation
Fixed automation is characterized by a high-volume, low-variability production process, distinct from the adaptability of FMS.
Computer-Integrated Manufacturing (CIM)
CIM is a broader concept encompassing the entire manufacturing process, including design and business functions, of which FMS forms a part.
