Controls how round a cross-section must be at any given slice. Applied independently at each cut — it doesn't control the overall cylinder.
Circularity vs runout: Learn the key differences, how each tolerance is evaluated, and what each one controls.
In this Question Line video, Jason reviews how Rule #1 controls the size and form of a feature of size, and what this means for ring gage design and inspection reporting.
In this Question Line Video, Jason gives a high-level overview of how polar probes and TIR checkers are used to inspect circularity or cylindricity.
Jason walks through the potential issues associated with using V-Blocks and how they can affect measurements of circularity and runout.
This video is in response to a question that we received on our question line from Amber. Amber asked us if the tolerance value for circularity can be obtained by subtracting the upper limit of...
In this question line video, Brandon reviews the differences between the GD&T callouts for circularity, circular runout, and total runout. To examine the differences in these concepts it is helpful to first review the Geometric...
