Outlook for change: streamlining a complex system, bolstering manufacturing efficiency, and instituting regulatory reforms

Article Abstract:

The US Department of Defense (DOD) is strongly trying to implement changes in the way it conducts business. The DOD is bolstering defense industrial competitiveness, instilling 'total-quality management,' and introducing new technology into weapon systems faster. In an era of slowly shrinking defense budgets, the DOD is also trying to fight the rising costs of major systems, the loss of production capability, and the manufacture of poor-quality products. In the past, the Pentagon has aimed at acquiring product technology to the neglect of manufacturing process technology. The latter technology is now being stressed under the jurisdiction of two Pentagon agencies. Quality control has become a top priority in weapon system decision processes. Manufacturing capabilities will be developed concurrently with weapon systems, as a result. New weapon systems will now specify contract requirements in industry how to design or manage. This streamlined procurement process gives program managers more opportunities to be cost-efficient.

Fundamental Operations

Article Abstract:

Steps in the manufacturing process from machining to final inspection have been automated for increased efficiency and productivity. New techniques are being used in machining and forming processes for improved speed and accuracy. Automated machines are controlled by computer in computer numerical control (CNC). When demand is high and design is stable, automatic assembly systems can be used. Computer-aided inspection and testing increase accuracy and throughput in manufacturing. Machining processed are illustrated along with photographs of automation technologies.

Streamlining Process Routes with Group Technology

Article Abstract:

Group technology groups parts together in part families to streamline processing routes. The success of such a system depends on the coding and classification system used for grouping. Some schemes, such as the Metal Institute Classification System (Miclass), have been developed to encode categories for computers. Visual inspection and production-flow analysis can also be used. There are concerns to aid in development of a group technology program. Diagrams illustrating before and after group technology effects on a manufacturing process are included.
