Measuring flatness on a round surface

[[To...]]

Hey guys,

So I'm trying to measure flatness on one of the surfaces on a shaft. I'm using the loop characteristic to do it, which seems to be working, but i when I print the report, instead of giving me a single flatness value, it gives me 48 of them (that's the number I used to make a full 360 sweep of the surface, but just for trial and error, I currently have it set to 3).

The highlighted surface is the one I'm looking to get a flatness measurement on.

Any ideas?

I don't think that will work as a loop. It looks like you're trying to skip the holes? It might be that you have to copy the stratagy and then paste, but then change the start angle.

Exactly. I am looking to bypass the .06 reamed holes. So I copy the flatness characteristic multiple times to make a full 360? How do I make the flatness show up on the report as a single feature instead of it showing up on multiple lines?

I don't think there is a shortcut for this I'm afraid, you'll just have to copy and paste and adjust the start angle in the circle path to the pitch you want.

You could pattern Points and then Recall Feature Points into a Plane. That'll speed you up a bit.

Why you don't use ploy line or circular path like this??

I will try that.

Now that I think about it, I can use two circle patterns and just have one of them go over the reamed holes, while using the fly scanning, to ignore them? Am I understand it correctly?

If you have fly-scan, then use that.

May I know why you are using 48 loops?, if I create a program like this definitely my QA manager will fire me..

If you don't want to do fly-scan, or don't have it. You can just pattern the feature, and recall the pattern into another feature. See the attached screenshots.
