The Design for Manufacturing Process

Design for Manufacturing (DFM), along with Design for Assembly (DFA) and Design for Inspection (DFI), is an important part of product design and development that focuses on optimizing the production process in order to maximize efficiency, reduce costs, and achieve consistent product quality. The primary objective of DFM is to create a product design that can be produced with minimal waste and cost while still meeting all the requirements of the end user. This requires careful consideration of factors such as material selection, part geometry, assembly processes, tooling concepts, and other manufacturing details.

By taking these factors into account early on in the development process, product designers and manufacturing engineers are able to optimize their designs for efficient manufacturing before committing them to production.

A key aspect of DFM involves selecting appropriate parts and materials for a given application. Designers must consider material properties such as strength, stiffness, corrosion resistance, and thermal conductivity in order to create a design that can withstand the rigors of production and fulfill the design intent of the product. They must also consider cost constraints in order to meet budget targets. By assessing part and material selection early on in the design process, designers are better able to identify components that will provide the best performance for their application while meeting any cost constraints.

The decisions on part and material selection must be recorded and shared with other members of the company as needed. Typically, PLM systems like Aligni provide this capability. Purchasing and inventory are updated regarding which versions of parts are required and the constraints and characteristics of those parts to make sure efficiencies are realized. The quality department is also notified on part specifications and tolerances through the PLM system and uses the information to develop testing and inspection processes.

Another important aspect of the DFM process involves optimizing part geometry for efficient manufacturing. This includes considerations such as reducing part complexity by utilizing assemblies instead of individual components, using symmetrical shapes to improve tooling efficiency and reduce costs, and designing parts with uniform wall thicknesses or other features which can facilitate more accurate machining operations. These techniques help ensure that parts are made quickly and accurately without compromising quality or performance.

For electronic manufacturing and PCB assembly, machine handling capabilities by pick-and-place machines is also a consideration. Small geometry components like surface mount electronics increase density and decrease PCB size, but require tighter machine tolerance and may decrease assembly yield.

The goal of DFM is to create a design that is optimized for efficient and cost-effective manufacturing. By taking into account factors such as material selection, part geometry, assembly processes, and tooling concepts early on in the design process, designers are able to identify potential areas of improvement and capitalize on them before committing their designs to production. This helps ensure that products are manufactured quickly and reliably without sacrificing quality or performance.  In this way DFM can help manufacturers realize significant cost savings while still providing high-quality products.

If you’re considering investing in DFM processes to find more production efficiencies, don’t forget to invest in a system that can manage the information needed to make DFM changes a reality. Sign up for Aligni today!
