Multiple Choice

Which practice helps demonstrate that parts will be easier to manufacture relative to competitors?

Explanation:
Using proven design-for-manufacturing techniques signals that parts will be easier to manufacture compared with competitors. DFM practices emphasize designing with the production process in mind, which includes simplifying geometry, favoring standard features, selecting materials and processes that are well-understood, and avoiding unnecessary tight tolerances unless essential. This reduces complexity, tooling setup time, inspection challenges, and the risk of rework, leading to faster production, lower costs, and more reliable quality. Complex geometries tend to increase manufacturing difficulty, tooling complexity, and cycle times, making parts harder to produce. Tight tolerances raise processing precision requirements and scrap risk, driving up costs and lead times. Longer lead times reflect scheduling or supply issues rather than how easy the part is to manufacture, so they don’t indicate manufacturability.

    Good coverage of core DML topics. The explanations help, especially when I stumble on a concept. The flash cards are handy for mobile review during commutes. It would be nice if there were a bit more depth on some manufacturing processes, but overall solid.
