[De...] Posted August 13 Share Posted August 13 I have a part with several different thru holes of progressively larger sizes. This is being run on a Contrua G2 with an RDS. Probe is point straight back for this measurement. I get air scanning the bigger the sizes with less data being available in a scan. I have slowed down the speed, but at this point I am at .075 to get 3/4 of the data. This obviously increases our cycle time. Are there any other ticks I could try besides reducing speed? Its been over 5 years since I've used an RDS. Link to comment Share on other sites More sharing options...

Then, on the scanning circle, click the "None" button under Projection (above Options) Click "Meas Ref" tab. Select "Feature" from the dropdown menu. Select the circle that used the touch points. Click Ok. You should be able to speed things up without having too much problem with air scanning. Link to comment Share on other sites More sharing options...
[De...] Posted August 14 Author Share Posted August 14 Thanks Tom, I'll give this a shot today. Link to comment Share on other sites More sharing options...
[De...] Posted August 14 Author Share Posted August 14 Is there a way to do this with cylinders or do I need to create separate circles and recall them into cylinders? Link to comment Share on other sites More sharing options...
[To...] Posted August 14 Share Posted August 14 Please sign in to view this quote. You could do something similar with a cylinder. Create a copy of the scanning cylinder, change the circle path strategies to 4 single points. If taking more than 2 circle paths in the scanning cylinber, change the number of circle paths to 2 in the points cylinder to save time. Create a secondary alignment using the points cylinder for the Spatial, X and Z origin (assuming it's in the +Y direction). You can leave the planar and Y blank and they will remain relative to the base alignment. In the scanning cylinder, click the alignment drop down menu, tick the "Keep Position" check box FIRST, then select the secondary alignment that you created with the points cylinder. I think I covered it all. As a foot note, when measuring a circle, especially for roundness, using the above technique to create a cylinder for the secondary alignment and assigning to the circle, will help ensure you're measuring the circle normal to its actual axis.

FYI to everyone, there is also a "own geometry" option in the same "meas Ref." tab that does basically the same thing Tom mentioned, at least in newer versions (I don't know if it was added at some point or not off the top of my head). It might be a bit easier and clearer than making the additional circles. Unfortunately for a cylinder, I think it might be necessary to make a separate circle using Tom's method or something similar.
