Flexible manufacturing system

Flexible manufacturing systems (abbreviated to FFS , also FMS for Flexible Manufacturing System) are multi-machine systems for processing workpieces. The individual machining stations are mostly standard numerically controlled machining centers . These are linked together via a transport and storage system in order to enable the automated flow of workpieces. In addition to the processing stations, you have workpiece and tool storage with the corresponding transfer stations. The clamping of the workpieces and the magazining of the tools can be carried out independently and in some cases in a centralized manner, which saves additional and distribution times for the machines. The automation of the transport also reduces space and personnel costs and shortens the lead times for orders.

The coordination of the individual NC controls, the transport control and other decentralized controls is carried out via a central master computer to which the individual cell computers ( flexible manufacturing cell ) are linked. The processing stations can take over one or more processing steps.

Although flexible manufacturing systems have a high potential for rationalization, they are nevertheless expensive to purchase and require highly qualified personnel who can operate them, so that their purchase is only worthwhile if there is an operational order situation with continuously high quantities.

The world's first flexible manufacturing system Prisma 2 went into operation in 1971 in the Karl-Marx-Städter VEB Fritz-Heckert-Werk . It consisted of 8 machining centers, a measuring bridge, 2 measuring machines and the transport system.
