[Er...] Posted January 2, 2020 Share Posted January 2, 2020 I guess nothing for the actual flatness value it self, theres a lot of information showing in piweb that might or might not be relevant. I think its Zeiss trying to flex the muscles of piweb showing how much more its capable of then the old reports. Some times the flexing just might be confusing. I dont know but I guess the corner points is the same as the nominal plane you have measured, if thats the case, it could give a hint of how much coverage you have of the plane. If thats the case I can see why they are presented. Link to comment https://qualityforum.zeiss.com/topic/16958-scanning-graph/#findComment-94896 Share on other sites More sharing options...

(beyond all normative rules).

[Er...] Posted January 2, 2020 Share Posted January 2, 2020 Ehh? The orientation should be derived from the feature in this case? Refering back to A and/or B must be an assumption that can be wrong?

Calculating any kind of Perpendicularity is misleading. Sorry!
