Point recall / Outliers

[[No...]]

Is there a way to prevent Calypso from recalling points that were already outlier filtered in the feature it recalls from?
I only want the "good" points recalled. Is this possible somehow?

[[Ma...]]

I think that NOT.

[[Er...]]

Why? Or for what purpose? Maybe there is another way to get the result wanted?

Yes, but there is no easy button.

1) Measure original feature and create a “dummy” characteristic (if needed) with desired outlier removal settings.
2) Export surface points from “dummy” characteristic using writeActualsToFile() function.
3) Read export file and extract x,y,z,i,j,k values from each line with a status of “0”
4) Write extracted data to a new file.
5) Import points from newly created file using “Recall Feature Points From File”

I feared as much.

Thanks, but I think this would take too much time to program and test. We need the results quickly, as we already wasted time and produced wrong results. So I'd need a solution that is quick and fool-proof to implement.

My problem is as follows:
I need to measure a large number of cylindrical bores. Each is measured in three depths as maximum inscribed circles. Additionally I want to recall the circle points to a maximum inscribed cylinder.
The problem is that in one depth the bore has a number of small axial ribs. To save measuring time, we scan over the ribs and eliminate them with the outlier filter afterwards.
Now when we recall all the circle points to the cylinder, the points on the ribs are back and have to be filtered out again. But now the outlier filter also affects the points in the other depths and eliminates so many points that in the end the diameter of the maximum inscribed cylinder is bigger than each of the inscribed circles, which can of course not be true.

Of course the easiest way to resolve this would be to scan in segments between the ribs. But since we need to measure a lot of parts with up to 18 bores each, and already occupy a whole machine day in day out with only this part, I'm trying to save every little bit of measuring time.

Is it possible that manually masked points are ignored when recalling points? It sounds logical as they are explicitly excluded by the user, not just by a filter rule. I have to be sure, but can't find any reliable information on this. At least the masked points of the cylinder look the same as in the circle and there are no filters active (for testing).

[[Er...]]

Yes, when recalling points from a feature Add Range Limits. You can set angles to exclude just like in Point Masking.

[[Da...]]

Can you reduce the number of points on the center circle ? If you go low enough the standard filters will take care the grooves. Might take some trial and error. Is there any chance the grooves are timed ?

[[No...]]

Hmmm, as you can see it took a 24 degree range to eliminate all the odd-looking points (although the ribs are much thinner than that). I don't think I can go that low with point density.
What do you mean by "timed" grooves? I'm not familiar with this term.

[[Da...]]

Are the grooves in the same place on each part. You can program multiple sections on each circle and check it in segments.

[[No...]]

They are. But checking in segments would take too much time.
We have now changed one of the programs to manual masking and it seems to work perfectly.
So this masking type really eliminates the points once and for all.

[[Er...]]

So did you go with Manual Masking in the Circles? Or when recalling the Circle feature into the Cylinder?

[[No...]]

In the circles of course. You can't do it on cylinders.
See my second image: No button there.

[[Er...]]

If I right click on the feature when recalling points I can add a range limit angle. That looks like it does the same thing.

[[No...]]

Yes, but wouldn't this affect all three circles in the cylinder? I wanted only one, so for me it was easier to do it on the circles.
