In manufacturing metrology, what term describes the process used to determine whether a tool is within specification as it wears?

• A. Gaging
• B. Calibration
• C. Measuring
• D. Inspection

Answer: (A)

Gaging is the practice of using gauges to determine whether a tool or part still falls within specified limits as it wears. It gives a direct go/no-go decision about conformity, which is exactly what’s needed to check tooling health over time and catch wear before it affects parts. Calibration, in contrast, is about adjusting instruments to read correctly, not about verifying the tool’s wear against tolerances. Measuring is simply taking a size, without implying a pass/fail verdict. Inspection is broader and can include many methods, but the gauge-based check described here is specifically gaging.
