Which is a QC check to ensure prototype accuracy?

• A. Visual aesthetic checks
• B. Regular measurement using flexible devices
• C. Machining alignment checks
• D. Assembly checks of multiple components

Answer: (B)

Ensuring prototype accuracy relies on obtaining objective dimensional data by comparing the part against the design specifications. This means measuring key dimensions and features regularly so you can see how closely the prototype matches the intended size, shape and tolerances. Using regular measurements with flexible measuring devices provides the necessary quantitative data. These tools can adapt to different shapes and surfaces, allowing you to accurately capture critical dimensions even on irregular features. By recording measurements and comparing them to the CAD-drawn tolerances, you can quickly identify any deviations and decide if the prototype needs adjustment. Visual aesthetic checks look at appearance, which doesn’t reveal dimensional errors. Machining alignment checks focus on whether the manufacturing setup is correct, not on verifying that the finished part’s dimensions meet the design. Assembly checks test fit between parts but don’t quantify how close individual features are to their specified sizes. The quantitative, ongoing measurement approach is what truly confirms accuracy in a prototype.
