Design for Manufacturability Definition

Design for manufacturability (DFM) is the practice of designing products in a way that makes the manufacturing process more efficient. The end goal is to produce high-quality products at a lower cost. A well-executed DFM process begins early on in the design phase and continues throughout the entire product lifecycle. It should involve a cross-functional team from engineering, quality, purchasing, and manufacturing as well as external supply chain partners. Getting input from all key stakeholders helps mitigate production issues, improve quality, and reduce the cost of goods sold (COGS).

FAQs

What is the concept of design for manufacturability?

Design for manufacturability (DFM) is the concept of optimizing the design of a product to make it easier and less expensive to assemble and mass-produce.

What are the general design rules for manufacturability?

Five fundamental principles underpin DFM, all of which must be carefully taken into account during the design phase:

  1. Process – The manufacturing process should consider factors such as cost, materials, volume, and tolerances
  2. Design – The design should conform to applicable good manufacturing principles
  3. Materials – Thermal, electrical, mechanical, optical, and other important properties should be considered when selecting materials
  4. Environment – The product must be designed to withstand the different environments that it is subject to
  5. Compliance – Products should comply with all applicable quality and safety standards
What does design for manufacturability (DFM) mean in design?

DFM in design is the practice of considering the buildability of a product early in the design stages to prevent late stage mistakes and ensure a more efficient manufacturing process. When adopting this methodology, engineering takes into account the assembly process, testing, and potential factory constraints at the early stages of design.
