Document Summary
A product design can be measured in terms of the efficiency of its overall assembly and ease with which the components can be retrieved, handled and mated. A product with high assembly efficiency will have few components, they will be easy to handle, and they will virtually fall together during assembly. The aim of design for assembly (dfa) is to simplify the product so that the cost of assembly is reduced. However, the consequences of applying dfa usually include improved quality and reliability, and a reduction in production equipment and part inventory. These secondary benefits often outweigh the cost reductions in assembly. Relative costs of different assembly methods by type and production volume. Design the product with a base component for locating other components. The base provides a foundation for consistent component location, fixturing, transport, orientation and strength. Don"t require the base to be repositioned during assembly. Problem for some components when stored in boxes or trays b.
