FMS Flexible Manufacturing System

Last updated on 

Flexible Manufacturing System (FMS) is a highly automated manufacturing system that integrates various computer-controlled machines, material handling equipment, and storage systems to produce a range of products in a highly efficient and flexible manner. FMS is designed to operate on a just-in-time basis, producing products as they are needed, and therefore minimizing the need for inventory and reducing lead times. This article will provide a detailed explanation of FMS, including its definition, components, working, advantages, and disadvantages.

Definition of FMS:

A Flexible Manufacturing System (FMS) is a highly automated and computer-controlled system designed to manufacture a variety of products with a high degree of flexibility, quality, and productivity. FMS is a highly integrated system consisting of several machines, material handling equipment, storage systems, and computer-controlled devices, all working together to produce high-quality products in a highly efficient and cost-effective manner. The system is capable of producing a range of products in a highly flexible and efficient manner, without the need for constant retooling or setup changes.

Components of FMS:

The FMS consists of several components, including:

  1. Computer Control System: This is the central component of the FMS, which controls and monitors all the operations of the system. The computer control system uses various software programs to manage the machines, material handling equipment, and storage systems, ensuring that they operate efficiently and produce high-quality products.
  2. CNC Machines: Computer Numerical Control (CNC) machines are the heart of the FMS, as they perform the actual manufacturing process. The CNC machines are highly automated and controlled by the computer control system, which ensures that they operate efficiently and produce high-quality products.
  3. Material Handling Equipment: Material handling equipment such as conveyors, robots, and automated guided vehicles (AGVs) are used to move the products from one machine to another in the FMS. The material handling equipment is also controlled by the computer control system, which ensures that the products are moved efficiently and accurately.
  4. Storage Systems: Storage systems are used to hold the raw materials, work-in-progress, and finished products in the FMS. The storage systems are also controlled by the computer control system, which ensures that the products are stored and retrieved efficiently and accurately.

Working of FMS:

The FMS works on the principles of automation, computer control, and integration of various components. The working of FMS can be explained in the following steps:

  1. Product Design: The first step in the FMS process is product design. The product design is created using computer-aided design (CAD) software.
  2. Process Planning: Once the product design is complete, the process planning begins. The process planning determines the manufacturing process required to produce the product, the type of CNC machines required, and the sequence of operations.
  3. Material Handling: The raw materials required for the manufacturing process are delivered to the FMS and stored in the storage system. The material handling equipment, such as conveyors or AGVs, are used to move the raw materials to the CNC machines.
  4. Manufacturing Process: The manufacturing process begins when the raw materials are fed into the CNC machines. The CNC machines are programmed to perform the required manufacturing process to produce the product. The CNC machines are highly automated and can perform complex operations such as drilling, milling, and cutting.
  5. Quality Control: As the product is manufactured, it is inspected and tested for quality. The computer control system monitors the quality of the product and ensures that it meets the required standards.
  6. Packaging and Shipping: Once the product is complete, it is packaged and shipped to the customer. The FMS is capable of producing products on a just-in-time basis, which minimizes the need for inventory and reduces lead times.

Advantages of FMS:

  1. Reduces Labor Costs: FMS requires less manual labor, as most of the manufacturing process is automated. This reduces labor costs and improves productivity.
  2. Increases Productivity: FMS is designed to operate on a just-in-time basis, producing products as they are needed. This reduces the need for inventory and improves productivity.
  3. Improves Quality: FMS is capable of producing high-quality products consistently, as the manufacturing process is automated and controlled by the computer control system. This reduces the chances of errors and defects in the final product.
  4. Increases Flexibility: FMS is designed to be flexible, as it can produce a range of products without the need for constant retooling or setup changes. This increases flexibility and reduces lead times.
  5. Improves Efficiency: FMS is highly automated, which improves efficiency and reduces the chances of errors or defects in the final product.
  6. Reduces Lead Times: FMS is designed to operate on a just-in-time basis, producing products as they are needed. This reduces the need for inventory and reduces lead times.
  7. Increases Capacity: FMS can produce products at a high rate, which increases capacity and reduces production time.

Disadvantages of FMS:

  1. High Initial Investment: FMS requires a high initial investment, as it involves the integration of several components and the use of advanced technology.
  2. High Maintenance Costs: FMS requires regular maintenance, which can be costly. The machines and equipment used in the FMS must be maintained to ensure that they operate efficiently and produce high-quality products.
  3. Limited Flexibility: FMS is designed to be flexible, but it may not be suitable for certain types of products or manufacturing processes. This limits its flexibility and may require additional investment in new equipment or technology.
  4. High Dependence on Technology: FMS is highly dependent on technology, and any failure in the computer control system or machines can disrupt the manufacturing process and lead to downtime.

Conclusion:

Flexible Manufacturing System (FMS) is a highly automated and computer-controlled system designed to manufacture a variety of products with a high degree of flexibility, quality, and productivity. FMS is capable of producing a range of products in a highly flexible and efficient manner, without the need for constant retooling or setup changes. FMS is designed to operate on a just-in-time basis, producing products as they are needed, which minimizes the need for inventory and reduces lead times. While FMS has several advantages, such as increasing productivity and improving efficiency, it also has several disadvantages, such as high initial investment and high maintenance costs. Overall, FMS is a highly advanced and efficient manufacturing system that is suitable for a wide range of products and manufacturing processes.
