Welcome to Flexible Manufacturing System (FMS)

FMSA flexible manufacturing system (FMS) is a manufacturing system in which there is some amount of flexibility that allows the system to react in the case of changes, whether predicted or unpredicted. This flexibility is generally considered to fall into two categories, which both contain numerous subcategories.

The first category, machine flexibility, covers the system's ability to be changed to produce new product types, and ability to change the order of operations executed on a part. The second category is called routing flexibility, which consists of the ability to use multiple machines to perform the same operation on a part, as well as the system's ability to absorb large-scale changes, such as in volume, capacity, or capability.

Most FMS systems comprise of three main systems. The work machines which are often automated CNC machines are connected by a material handling system to optimize parts flow and the central control computer which controls material movements and machine flow.

The main advantages of an FMS is its high flexibility in managing manufacturing resources like time and effort in order to manufacture a new product. The best application of an FMS is found in the production of small sets of products like those from a mass production.

A flexible manufacturing system is true mid-volume, mid-variety manufacturing system consisting of a series of flexible machines, automated material-handling systems, automated tool changer, other equipment, such as coordinate measuring machines, part washers etc, all controlled by a high-level centralized computer. It has a high production rate and flexibility. As the name suggests, it permits both sequential and random process at a wide variety of parts.

The essential physical components of the FMS are:

  1. Potentially independent NC machine tools which are able to perform multiple tasks and having automated tool interchange capable abilities;
  2. Automated material handling systems to make the parts from one machine tool to another;
  3. All the components are hierarchically computer controlled;
  4. Coordinate measuring machines;
  5. Part washing devices etc.

Parts are mounted onto fixtures which inturn are mounted onto special pallets before machining. The material handling system then moves it to an idle machining centre.
