[Ra...] Posted March 10, 2021 Share Posted March 10, 2021 Can someone help me understand true position results. If I have a point and I check true position in the Y direction only. Lets say true position is .30 That means it can be +.15 and -.15 from that point in the y direction. The result value is represented how? .28 is on the north end and anything less than 15 is below the point? Link to comment Share on other sites More sharing options...

[Ra...] Posted March 11, 2021 Author Share Posted March 11, 2021 just came across the formula. under-root ΔX2 + ΔY2 * 2. How can i determine which way it is out though? There are no charts for true position in pi web results. Thank you sir. Link to comment Share on other sites More sharing options...
[He...] Posted March 11, 2021 Share Posted March 11, 2021 You can turn on additional printout under "Resources", "Characteristic settings editor", that should give you the X,Y,Z. Link to comment Share on other sites More sharing options...
[Jo...] Posted March 11, 2021 Share Posted March 11, 2021 Please sign in to view this quote. As stated, Position reported is the deviation VALUE from the target calculated as stated.. What you want is Resources> Characteristics settings editor> Additional printout. That will give the components of error in both axis. If you need a visual representation, copy your characteristic and modify it as "Best fit of bore pattern" . Even if it is a singular position you can uncheck the translation and rotation option and get a graphic of location. You will need to select detailed report to view in PiWeb.

As Ryan Stauffer once said, “The benefit of using BFBP in order to plot your position results, even if you’re not using Best Fit, is worth the price of admission.” Link to comment Share on other sites More sharing options...
[Ri...] Posted March 11, 2021 Share Posted March 11, 2021 Starting with Calypso 2019, maybe 2018, True Position & Concentricity will provide a native XY plot in PiWeb for you. If you are using Polar Coordinates you will have to use the BFBP Plot unfortunately. 🙁 Link to comment Share on other sites More sharing options...
