V-Blocks are popular tools used with manual inspections, but come with a unique pitfall that can impact the accuracy of measurements. In this video, Jason walks through the potential issues associated with using V-Blocks and how they can affect measurements of circularity and runout.
In this question line video, we explain when to use the diameter symbol in a feature control frame. The examples below illustrate the unique tolerance zones shapes and sizes for position, perpendicularity, straightness, runout, and cylindricity controls.
The video below is in response to a question that we received on our question line from Jeff. Jeff asked us if concentricity is always equal to half of the runout value. ASME Y14.5 defines...
Runout is how much one given reference feature or features vary with respect to another datum when the part is rotated 360° around the datum axis.
Total Runout is how much one entire feature or surface varies with respect to a datum when the part is rotated 360° around the datum axis...
