[Ed...] Posted June 2, 2023 Share Posted June 2, 2023 Hi, I need to evaluate this MAX WAVINESS! Like I understood, this is related to cylindricity? Can someone give me some advice in this case? Is it possible do evaluate something in Calypso? BREkrānuzņēmums 2023-06-02 113517.jpg Link to comment Share on other sites More sharing options...
[Da...] Posted June 2, 2023 Share Posted June 2, 2023 I haven't done this myself, but it should be pretty straightforward using the waviness evaluation. You put the values into the dialog, check "double amplitude", and you need a certain amount of points (300 waves per rotation max for the Fourier analyis means: 300 upr * 7 points per wave = 2100 points for each evaluated circle minimum, if you use a cylinder you need 2100 points minimum per section). Use the smallest probe diameter possible and slow speeds. The shown formula "RTA curve" is what you need. I think you need to limit the values in Harmonic and I'm not sure about the Type of Evaluation, but maybe you can take it from here. Link to comment Share on other sites More sharing options...

Thank you very much 😉 About number of points, the main thing is to have at least 2100 points per circle, it is good like in attached picture? Only thing I don`t understand is about "Upper and Lower Limits"? What should be there? How you understand it? What does this evaluation shows to me in overall?Captu1re.JPG Link to comment Share on other sites More sharing options...
[Da...] Posted June 2, 2023 Share Posted June 2, 2023 The number of points is good. The drawing calls for all harmonics <= 300 waves per rotation, so 0 and 300 should be your limits. That’ll give you a pass or fail for every harmonic, not only 2 as you have now. See where the waviness goes down and then up again from around 270 upr? That’s the range where your waviness might fail. Link to comment Share on other sites More sharing options...
