| Tóm tắt≠ | Design for Manufacturing and Assembly (DFMA) is a systematic methodology for creating products that are inherently easier and less expensive to manufacture and assemble. Developed by Boothroyd, Dewhurst, and Knight, DFMA evaluates design choices based on their impact on production cost, quality, and speed, guiding designers toward solutions that balance performance, manufacturability, and economics. | Tolerance stack-up analysis is a method for predicting the cumulative effect of manufacturing tolerances on the final dimensions and fit of assembled components. When parts with individual tolerances are assembled together, their tolerances combine in complex ways, often producing a result that is worse than each part individually. Stack-up analysis ensures that the final assembly will function correctly despite individual part tolerances, or identifies where tighter tolerances are necessary. |
