[K...] Posted January 5 Share Posted January 5 I defined a circle Ø160 on machined bore, and reported roundness 0.088, but when I checked roundness by Marposs gauge, it measured 0.027. Should I have to use filter and other options in evaluation. Link to comment Share on other sites More sharing options...
[Ma...] Posted January 5 Share Posted January 5 Yes, as a general statement. Applying the circular algorithm LSQ, MI, MC, etc… is something else to consider Link to comment Share on other sites More sharing options...

[Ün...] Posted January 6 Share Posted January 6 Yes, you should use filters and outliers. Also, devices that measure with 2 opposing pins, such as Marposs, usually show low roundness values. This varies depending on the processing method of the part Link to comment Share on other sites More sharing options...
