Design and Manufacturing

Design and manufacturing are closely related fields focused on product creation
Design involves conceptualization, planning, and development of products; manufacturing focuses on actual production
Design involves identifying customer needs, creating product concepts, developing prototypes, testing, refining designs, and ensuring functional, aesthetic, and economic requirements
Manufacturing includes selecting appropriate processes, acquiring materials & equipment, producing products efficiently, ensuring quality control, and distributing to customers
Design & manufacturing are interdependent; good design leads to efficient & cost-effective manufacturing, and effective manufacturing helps bring high-quality products to market

Product Lifecycle Management (PLM)

PLM is a business strategy to manage the entire lifecycle of a product (from conception to retirement)
PLM integrates people, data, processes, and business systems to create a unified product development strategy
PLM improves product quality, reduces costs, and speeds up time to market

Design for Manufacturing (DFM)

DFM is a process of designing components for easy manufacturing at a lower cost
DFM involves lowering product complexity, optimizing performance, and redefining the product
DFM is important in product development cycles due to its ability to lower cost and time savings by implementing DFM early in the process
DFM involves all stakeholders (manufacturers, engineers, suppliers, designers) to consider every need during planning
Five principles of DFM: Process, Design, Materials, Environment, and Testing

DFM Principles (details)

Process: Selecting the right manufacturing process to use lower-capitalized strategies for cost-effective production; optimize processes to fit components considering tolerances and needed materials
Design: Simple designs are preferred over complex ones to minimize cost, manufacturing/use, and maintenance risks; designs should follow good manufacturing principles with specific details for thicknesses, tolerances, texture, and consistency
Materials: Choosing the right materials early on can save time & money; the choice of materials impacts cost and quality, and consider mechanical properties, flammability, conductance, and thermal properties
Environment: Design parts with the intended operating environment in mind considering all conditions to allow proper performance; parts need to operate correctly in the expected environments
Testing: All products and components need thorough testing to comply with industry standards (e.g., industry, internal, company standards); testing needs to be done throughout each DFM stage.
