Group Technology (GT) Defined A manufacturing philosophy in which similar parts are identified and grouped together to take advantage of their similarities in design and production Similarities among parts permit them to be classified into part families In each part family, processing steps are similar The improvement is typically achieved by organizing the production facilities into manufacturing cells that specialize in production of certain part families

Overview of Group Technology Parts in the medium production quantity range are usually made in batches Disadvantages of batch production: Downtime for changeovers High inventory carrying costs GT minimizes these disadvantages by recognizing that although the parts are different, there are groups of parts that possess similarities

Part Families and Cellular Manufacturing GT exploits the part similarities by utilizing similar processes and tooling to produce them Machines are grouped into cells, each cell specializing in the production of a part family Called cellular manufacturing Cellular manufacturing can be implemented by manual or automated methods When automated, the term flexible manufacturing system is often applied

When to Use GT and Cellular Manufacturing 1. The plant currently uses traditional batch production and a process type layout This results in much material handling effort, high in- process inventory, and long manufacturing lead times 1. The parts can be grouped into part families A necessary condition to apply group technology
