An FMS is a highly automated manufacturing cell consisting of interconnected CNC machine tools controlled by a distributed computer system. It integrates flexible automation, CNC machines, computer control, automated material handling and group technology. An FMS is suitable for mid-volume production of parts that can be grouped into families. It provides increased machine utilization, reduced space, and greater responsiveness compared to dedicated lines. The main components are workstations, a material handling system, computer control system, and human resources.
