What is the typical method for inspecting machined parts for accuracy?

• A. Using visual inspection only
• B. Using precision measuring tools
• C. Testing the part's performance under load
• D. Conducting a surface finish measurement

Answer: (B)

The typical method for inspecting machined parts for accuracy involves using precision measuring tools. These tools, such as calipers, micrometers, gauges, and coordinate measuring machines (CMM), allow for precise measurements of dimensions, tolerances, and geometrical characteristics of the machined part. This method ensures a high level of accuracy and consistency, which is critical in manufacturing to meet specifications and quality standards. While visual inspections can provide an initial assessment of the part's appearance and obvious defects, they cannot reliably determine dimensional accuracy or critical tolerances. Testing a part's performance under load focuses on functional aspects rather than dimensional measurements, and conducting surface finish measurements is specific to evaluating the quality of the surface rather than overall accuracy. Therefore, precision measuring tools are essential for thorough and accurate inspection of machined parts.
