Design for Manufacturing and Design for Assembly is the integration of product design and process planning into one: Design for Manufacturability (DFM). Design for Assembly is concerned with reducing product assembly costs and minimizing the number of assembly operations, and individual parts tend to be more complex in design. Design for Manufacturing is concerned with reducing overall part production costs and minimizing the complexity of manufacturing operations.
The overall objective is to design a product that is efficiently and economically manufactured. DFM?s importance is emphasized by the fact that design decisions determine about 70% of the manufacturing costs of a product (cost of materials, processing, and assembly). Production decisions (such as process planning or machine tool selection) are responsible for only 20%, with the remaining 10% being other processes. In simple terms, integrating DFM should reduce the cost and difficulty of manufacturing.
The reduction of the number of parts in a product is feasibly the best opportunity for reducing manufacturing costs. Fewer parts imply fewer purchases, handling, processing time, development time, engineering time, and so on. Some approaches to part-count reduction are based on the use of one-piece structures and selection of manufacturing processes that optimize the process.
There are quite a few benefits to using standard components versus custom ones. For starters, they are highly available, which reduces product lead times. The manufacturer that needs a standard part has less worry. They will get it on time from the supplier because it is readily available and can choose which supplier offers the best deal for the quantity needed in the time frame necessary to remain on the production schedule. More importantly, they are less expensive than custom.
Multi-functional parts reduce the total number of components in a design. Parts that can be classified as multi-use can be shared within multiple products that the manufacturer has. It allows one purchase order from the supplier to utilize in more than one product. All of which allows for versatility, less production time, and ultimately less cost. The goal is to minimize the number of categories, and the outcome is a set of standard part families in which multi-use parts are established. Once organized, the manufacturing process is standardized for each part family. Now allowing the ability to skip operations that are not required.
