Design for Mass Production of Small Lotsize Mechanical Systems

摘要

By reconsidering the goals of Mechanical Design, a new working method for Designis defined in the study, in which method the manufacturing process planning is merged into Design. By the use of CAD/CAM techniques, the numerically controlled (NC) programming has been automated, by which the use of NC machine tools become economically justifiable for small lotsize mechanical components. The working method puts aside the conventional design procedures, avoids drawings and brings back manufacturability considerations to the designer. Good results are only possible by a high degree of standardization and automation (technology, manufacturing methods, palletizing systems, tool changing device, tool management, Manufacturing Families). The new design approach also has a great influence on the manufacturing organization. It leads to a manufacturing process of small lotsize mechanical parts, which has the characteristics of mass production. The results of the study are based on proven applicability in a pilot project at Philips Lighting Eindhoven.
