Design for Manufacturability (DFM)
In translating the functional product design into a manufacturer product designers must consider many aspects They can use a variety of methods and alternative material to make a product Material choices can be ferrous iron and steel) aluminum copper bra magnesium zinc tin nickel titanium or several other metals The nonmetals include plastic wood leather rubber carbon ceramics glass concrete as well as several others. Further all of these materials can be formed cut and shaped in many way The are extrusions starvings rolling powder-metal forgings castings injection milling along with a very large selection of machining processes In designing for maneuverability it is also desirable to keep the numbers parts a minimum In electronics manufacturer accomplice circuits that have been in different components into large and larger integrated only does this wood leather rubber carbon as well as several others. Further, all of these materials can be formed cut and shaped in man are extrusions starvings rolling powder-metal forgings castings injection milling along with a very large selection of machining processes.
as far, but it also reduces the physical size and increases reliability Reliability is increased by eliminating the many connections necessary when the circuits were in separate parts Exhibit 3.6 shows how to reduce a simple bracket from five parts to one by focusing on the purpose of the part the fabrication and the assembly procedure used for its manufacture.
The output of the product design activity is the product’s specifications These specifications provide the basis for production-related decisions such as the purchase of materials selection of equipment assignment of workers and the size and layout of the production facility Product specifications while commonly thought of as blueprints or engineering drawings often take other forms ranging from precise quantitative and qualitative statements to rather fluid guidelines Physical products tend to have traditional blueprint specifications while a service firm’s design specifications tend to be more general While designing for maneuverability we must still remember to design for the consumer A basic rule in design is to Be obvious Design a product so that a user can look at it understand it and figure out how to use it–quickly and without an instruction manual.
