Cylindricity

Cylindricity checks ensure that all the specified points are the same distance from a common axis. The tolerance establishes the maxi- mum allowable distance between two concentric cylinders containing the measurements of that part.

Evaluation Process within SA:

  1. Two coaxial cylinders are built bounding the extents of the data.

  2. The cylinders are allowed to freely rotate to establish the minimum distance between them while still containing the data.

  3. The final distance between these cylinders is compared to the tolerance for evaluation.
