[Mi...] Posted May 18, 2022 Share Posted May 18, 2022 I have been told not to mix strategies because filter/outlier won't work then... but I haven't seen any warnings from Zeiss, and in trying it it definitely still does something. Examples: Plane with both circle paths and polyline strategies. OR A Cylinder with both circle paths and polylines how does the filtering handle this? Also do you filter based on what the strategy is, or what the feature is? Meaning if I scan a circle path on a plane, do I filter it with wavelength based on the feature size? or UPR based on the circle path size? Thanks!

[Cl...] Posted May 18, 2022 Share Posted May 18, 2022 For a cylinder with both circle paths and polylines, I would use Gauss filtering for the circle paths and for polylines, I'd use spline. "Meaning if I scan a circle path on a plane, do I filter it with wavelength based on the feature size? or UPR based on the circle path size"? Wouldn't the UPR setting only apply to circular features?

[Mi...] Posted May 19, 2022 Author Share Posted May 19, 2022 Please sign in to view this quote. That's exactly what I asked. Our parts are almost always round, so scanning circle paths on planes usually makes more sense. But, the person I learned from will then use UPR, and he says you can't mix strategies - polylines and circle paths. Although it seems that for really tight tolerance cylinders, using lines and circles would help in some cases.

[Ma...] Posted May 19, 2022 Share Posted May 19, 2022 UPR is used on cylinders - not used on planes regardless of strategy. Based on path I would not recommend UPR for polylines on cylinders ( only for helix and circles ) - but I am not dealing with tight tolerances.

[Ma...] Posted May 19, 2022 Share Posted May 19, 2022 Using UPR for circular scan on a face is certainly valid. On many roundness measuring devices it is the only option. If you choose to mix strategies, use an appropriate wavelength filter instead.

[Er...] Posted May 19, 2022 Share Posted May 19, 2022 I'm really bad about not setting filters specifically for features. I only change the default when I have "fishy" results. The Zeiss Cookbook of 100+ pages should be a part of the help files, or at least included in the training.
