NB These classifications of batch size are open to considerably much wider interpretation obviously depending upon a specific company s production requirements and the actual machined part s complexity material cost machining operations and its dimensional size and so on At any workpiece quantity greater than the Job shop levels having similar production processes undertaken allows them to be grouped into families according to their dimensions tolerances workpiece materials etc. This technique of allocating components to be machined into similar groupings is often termed Group Technology 24. It is vitally important that both the Sales and Marketing personnel are aware of the company s patterns of manufacture and their capabilities if the company is to be able to rapidly respond to their customer s needs. The sales force will be able to relate a customer s requirements to the standard range of parts produced with the manufacturer being in a position to fine-tune even small production runs for maximum efficiency. By comprehending the manufacturing process for the company s standard-ranges allows the optimum conditions of production to be utilised even when modified standards or even specials have to be produced. Flexibility here plus the ability to cater for unique customer needs may offer new market opportunities for the company. ii 24 Group Technology . GT is essentially utilised for groupings in two distinct varieties i Component geometry - the closeness of shapes ii Similar production processes - such as Milling Drilling Turning etc. The benefits of utilising a GT-approach to manufacture are smoother logistical work-flow simplified work control more efficient plant layout and improved use of floor-space contributing to enhanced manufacturing versatility and better response to variable .
