[To...] Posted February 25, 2020 Share Posted February 25, 2020 I have a part that has a machined surface that has multiple radii on it, I have to pull points at different lengths from the datum. I will have a model for this, I'm trying to figure out how I will go about getting the points. Since it's not a standard feature, I think I will have to program the points and tell the stylus to give me the values from that, but I'm concerned if I don't get the angle just right I'll get bad data. Does anyone have a good idea on how I should attack this?CMPR AIR INT TURBO.pdf Link to comment https://qualityforum.zeiss.com/topic/16438-pulling-points-off-a-non-standard-feature/ Share on other sites More sharing options...
[Cl...] Posted February 25, 2020 Share Posted February 25, 2020 So, it sounds like you are trying to measure small radii? If I'm understanding you correctly, you aren't able to extract an appropriate feature? Have you tried extracting as "Define Circle on a cylinder"? One option would be "Space Points" Their more for profile, but at least they would tell you were your surface is.

You can trace a curve using CAD model section at that particular area, then select a point in the curve,change the normal of points According to drawing requirement, delete the unwanted points. I have not programmed this like profile, l don't know it will work or not... just telling my idea.

I'm getting the model today, but based on other jobs I'm not confident I can extract multiple radii off that feature - there are 7-8 different radii around that feature, some are only 1.0mm in length. Thanks for the tips though, I will try them out.

[Ch...] Posted February 25, 2020 Share Posted February 25, 2020 Finally, another turbo. I remember my first compressor housing scroll profile. Instead of reporting multiple radii, why don't you just report the one profile callout that's on the print? That is a pretty typical compressor housing scroll callout.

Do you mean combine all the hits into a feature or pull whatever Calypso thinks that feature is, use that as the feature and do the profile from those? Again, I don't have the model yet so I'm just guessing Calypso won't know what to make of it. I don't have the curve package either.

[Ch...] Posted February 25, 2020 Share Posted February 25, 2020 I see, with no curve and no model then you are only left with reporting the radii. I wish I had better advice for you, but I don't think that will work very well. I hope you can prove me wrong but that is a lot of very short radii to try and measure. CAD models or atleast the curve package is a must for measuring turbo's.
