What is Design For Manufacturing (DFM)?


Design for Manufacture or Design for Manufacture (DFM) is to improve the design of a part, product, or component to make it cheaper and easier. DFM is concerned with the efficient design or engineering of an object, generally during the product design phase, when it is easier and less expensive to do so, in order to reduce the cost of production. This allows manufacturers to identify and prevent errors or inconsistencies.


Principles of DFM

DFM occurs early in product development, before tooling and assembly, when the product is being designed. Doing so will make manufacturing less time consuming, thus reducing costs and increasing ease of production. The exact DFM process will depend on the product being designed and manufactured. DFM's general principles include designing objects for efficient assembly, standardising materials and components, minimising part numbers, and minimising the number of manufacturing runs required on parts in the assembly process. Other essentials for an effective DFM include parts standardisation to save on parts costs, simple designs, which can reduce complexity or the number of parts required, and reduce setup time.


What is Meant by Design for Manufacture?

Usually, when this term is used, it refers to Design to Manufacturing and Assembly (DFMA), a more general term for an engineering approach that improves time to market and reduces the manufacturing cost of a manufacturing process during the initial design phase.design for manufacturing Previously, however, this referred to two separate practices, DFM and Design for Assembly (DFA). Design for assembly prioritises the ease of assembling something and is concerned with reducing the cost of assembly, while DFM focuses more on concepts such as parts design and thus can also reduce the production cost of the parts themselves.


Why is Design for Manufacturing Important?

For any company that wants to make money and make profitable products, DFM is critical to achieving efficiency, speed and high production rates. It is believed that about 70% of the cost of manufacturing a product stems from design decisions made in the early design stage, such as the materials used or manufacturing methods. Therefore, the Dubai Financial Market has the potential to reduce costs significantly. Focusing on the design phase, available through the DFM, will significantly reduce final production costs. It can also enable the identification, quantification and elimination of waste or inefficiencies at various points during the production and manufacturing process. It can also be used as a benchmarking method, and in doing so, the company can measure the products of its competitors.


Advantages/Benefits

  • Products made of DFM will have lower production costs

  • Faster time to market

  • Shorten the product development process

  • Production will be accelerated sooner

  • Parts can be combined to reduce assembly steps and parts count

  • Capture and eliminate mistakes or errors

  • Higher product quality, as the design can be refined and enhanced at every stage

  • Since construction activities can be relocated from site and located elsewhere, DFM can create a safer work environment

How Long Does DFM Take?

Of course, the lead time for any process will depend on the product, the parts, the manufacturing process and the complexity of the processes required. However, on average, the DFM process takes about two weeks to complete. This number can increase to three or even four weeks for more complex products.
