[Fr...] Posted October 16, 2020 Share Posted October 16, 2020 Hello If I change the setting for Tolerance from Number Scale to Absolute Value it only works on Custom Report and not on Pi-Web Report. Does anyone know where to change the setting so it works for Pi-Web Report as well. Link to comment Share on other sites More sharing options...
[An...] Posted October 29, 2020 Share Posted October 29, 2020 Hello, which pwb report are you using? I mean, are you using a default pwb report or something else? Link to comment Share on other sites More sharing options...
[Fr...] Posted October 30, 2020 Author Share Posted October 30, 2020 Hello, I´m using the default. Calypso 6.8.16 - PWB plus 7.0.10.0 Regards Frank Link to comment Share on other sites More sharing options...
[An...] Posted October 30, 2020 Share Posted October 30, 2020 Ok could you post the same example from custom and from pwb. Just to understand better. Link to comment Share on other sites More sharing options...
[Fr...] Posted October 31, 2020 Author Share Posted October 31, 2020 I have a picture with an example, but I have a issue getting it attached here... I´ll be back.. Link to comment Share on other sites More sharing options...
[Fr...] Posted October 31, 2020 Author Share Posted October 31, 2020 Hi In the meantime I have installed Calypso version 7.0.02 PWB Plus 7.4.6.0 and when I select Absolute Value, there is now coming an info who says "PiWeb reporting does not support the amount mode" So maybe that´s the reason....... But thanks for your time. 🙂 Best Regards Frank Link to comment Share on other sites More sharing options...
[No...] Posted November 27, 2020 Share Posted November 27, 2020 Please sign in to view this quote. Exactly. Instead of eliminating such issues, it's probably cheaper to mark them as a feature. 🙄 Link to comment Share on other sites More sharing options...
[Gu...] Posted December 8, 2020 Share Posted December 8, 2020 The Number scale mode is the default deviation calculation in CALYPSO. If dimensions in a drawing will be checked based on a standard, e.g. ISO or ASME, the number scale tolerance mode must be used for a standard-compliant evaluation. https://en.m.wikipedia.org/wiki/Observational_error Measurement error is a term from Measuring technology or Metrology. The latest definition for it can be found in the International vocabulary of metrology. Measurement error is defined there as a difference: Measurement value minus reference value.[1][2] International vocabulary of metrology https://en.m.wikipedia.org/wiki/Joint_C ... _metrology https://www.bipm.org/en/publications/guides/vim.html What happens with the different calculation methods when comparing the coordinate deviation? Assumtion: Various parts are measured. The coordinates are always the same. Example: X coordinate: actual: -74.881 nominal: -75.000. Result with the same calculation method Number scale in PiWeb. Nominal and actual from different system => The result is the same, with the same actual values. If you compare without PiWeb: Result with different calculation method with Nominal and actual from different system => The result is different, with the same actual values. X coordinate: actual: -74.881 nominal: -75.000 Question: Do the parts fit together? For the same measured values, scattering is generated by the different calculation method. Is this correct for the production process? What are the standards on the drawing? (ISO, ASME…) Link to comment Share on other sites More sharing options...
[No...] Posted December 9, 2020 Share Posted December 9, 2020 Of course it's not a good idea to mix up calculation methods (like in your second example). But what would prevent PiWeb from converting all the results to amount mode if this is the selected mode? That would eliminate the different deviation results as well. Then everybody could select the mode that suits him/her best, like we did in Calypso for many years. The fact is that Calypso supports amount mode and from that point of view, PiWeb reporting is not fully compatible. Many people are used to calculating in amount mode for decades, especially when all the drawings contain basic dimensions and not coordinate values. It's hard to teach them otherwise. If I suddenly confront my engineers with number scale results, they might correct their injection molds in the wrong direction, because they're used to the old calculation method. Many of them don't even know there exists another method, nor do they know or care much about ISO or ASME. They just want to know if and by which amount they need to correct. That's the main reason why I still use the old custom report, despite all the nifty visualization tools of PiWeb. Link to comment Share on other sites More sharing options...
[Gu...] Posted December 9, 2020 Share Posted December 9, 2020 Digital data exchange in Industry 4.0 requires standards: These methods are defined in ISO and ASME. Digital data exchange between companies is already possible today. This assumes that the same deviation is calculated for the same actual and nominal value. This is a prerequisite for using the ISO / ASME. A uniform format is required for global comparability of measurement values. Number scale is required to compare measurement results from different workpieces or different measuring systems around the world. PiWeb reporting is an element of the PiWeb product line. PiWeb can evaluate and compare results from different measuring systems all over the world. To obtain consistent evaluations, the standard number scale deviation calculation must be used. For globally comparable deviation calculations, the corresponding standards (ISO, ASME…) must be met. This requires the CALYPSO default setting Number scale tolerance mode The amount tolerance mode was originally made to get the deviation in vector direction on curved sheets. There is now the “Space Point Distance" available. This works in Number scale mode Based on ISO / ASME: What is the deviation, if you have: X coordinate: actual: -74.881 nominal: -75.000 What is the deviation of a “Position” if you have: X coordinate: actual: -74.881 nominal: -75.000 https://en.m.wikipedia.org/wiki/Observational_error Measurement error is a term from Measuring technology or Metrology.
