The design of industrial parts must be done in such a way that it not only meets the needs and specifications of the design, but also can be produced economically and efficiently. This approach to designing parts improves productivity and allows the manufacturer to remain competitive. This broad perspective is known as design for manufacturing and is a comprehensive approach to product manufacturing and integrates the design process of industrial parts with manufacturing materials, process planning, assembly, testing and quality assurance. Effective implementation of design for manufacturing requires that design engineers have a basic understanding of the characteristics, capabilities and limitations of materials, production processes, machinery and equipment.
