Cylindrical Stylii Calibration

[[Er...]]

I am needing to use a cylindrical stylus on one of my programs but have never used one before. What is the procedure for calibrating this type of stylus ? I am using this on a VAST XXT and only needing to qualify at A0 B0. Also, when using this type of stylus along an edge with varying z-values (about .060" variation across the entire length), how do you program your scan path to ensure that the stylus is always maintaining contact with the edge you are wanting to inspect?

Cylinder styli are not natively handled by the XXT. There are workarounds though.

I suggest buying a spherical bottom cylinder styli if possible because since they have a sphere on the bottom, they are qualified normally.

To an extent. (No disrespect meant).
Cylindrical and Spherical Bottom Cylindrical styli are never perfectly normal to the axis of the head, let alone the CMM and or part.
On Spherical Bottom Cylindrical styli, the stylus will perform exactly as described by Mr. Shomaker.
What you need to watch for is depth of the stylus into a feature, assuming the stylus is not perfectly aligned to the axis of the Probe head movement you can basically shank on the cylindrical portion of the stylus that is not qualified.

You can test your stylus on a Ring Gage.
Set the equator as close to the top of the ring gage as possible, scan or take points.
Collect results.

Lower the stylus as far as possible to use the cylindrical portion, scan or take points
Collect results and analyze.

In my sheet metal days, I ran into this quite a bit.
