A tolerance-based percentage compares measurement spread with the specified tolerance width. A study-variation percentage compares it with the variation represented by the study. A variance-contribution percentage uses variance components rather than the same standard-deviation ratio. These values answer different questions and should not be exchanged as if they were equivalent scores.<\/p>\n<p>The distinction explains why changing the selected part range can change a study-relative percentage even when the measuring method has not improved. It also explains why a method can look adequate against a broad tolerance while struggling to detect smaller process changes. Review the reported basis alongside the actual purpose of the check.<\/p>\n<p>Apply the customer&#8217;s approved measurement-system requirements and the relevant quality plan when judging acceptability. A familiar threshold is not a universal release rule for every feature, risk level and study design. Where the result is marginal, the next decision should address the consequence of measurement error and the available improvements, not merely whether a rounded percentage falls on one side of a convenient line.<\/p>\n<p>Gage R&amp;R also does not establish every element of measurement quality.

For CNC components, it helps answer a practical question: can the inspection method reliably distinguish the dimensional changes that matter? A calibrated instrument alone does not answer that question for the complete method, fixture, feature and operator combination. Suppose two inspectors disagree about a bore diameter. The disagreement could reflect real differences between the locations measured, inconsistent seating, contact technique or an unsuitable measurement procedure. Adjusting the machining process before understanding the check can create a second problem instead of solving the first.
