[Ti...] Posted November 18, 2021 Share Posted November 18, 2021 Can i make a rotary table axis alignment using a two planes or one cirkle and one plane? I have a part where i need to clamp on the bottom diameter witch a special made clamping structure that has 3 openings on the diameter. It is not possible to measure this diameter when the BA does not rotate with RT is active because my probe will then collide with the clamping structure.

[Ow...] Posted November 18, 2021 Share Posted November 18, 2021 Could you post a picture of the set-up? I suppose you could use the same concept as the Sphere method and use a plane scanned at two different RT Angles and then a perpendicular from the center bore?

Yes, you can measure a plane and a circle, and create a perpendicular with the two features; and use the perpendicular for your RT axis. It works great for large bearings, anyway.

[Ti...] Posted November 18, 2021 Author Share Posted November 18, 2021 @Owen Long: You mean i only have to use one plane? at two different RT angles? See attachment for the setup. the red structure is the clamping structure. @Keith: How does it work because i will need to make a symmetry out of these feautures and also measure at two different RT angles?

[Ke...] Posted November 18, 2021 Share Posted November 18, 2021 No Symmetry; just a perpendicular; similar to the single sphere method. I'm guessing that the longer the perpendicular, the better; if you are working with a longer/taller part(?)

[Ti...] Posted November 18, 2021 Author Share Posted November 18, 2021 On the top i can measure a circle 360° but on the bottom i need to turn the RT because i can't scan the plane in one time. I need to rotate the RT and measure the plane in two times, so i need to make a recall of a plane and then make a perpendicular of the plane.rt alignment using cirkles.PNG Link to comment https://qualityforum.zeiss.com/topic/11558-rt-axis-alignment/#findComment-57222 Share on other sites More sharing options...

If the plane is reasonably flat, I'm not sure that you would need to scan the full 360 degrees... the tooling ball method only uses a point at 6 locations to calculate a plane & circle.

[Ti...] Posted November 19, 2021 Author Share Posted November 19, 2021 The circle is on top so i can measure it 360° buth de plane on the bottom i can't measure it in one time. Because the RT guide says that you need to measure the features as far as possible from each other to make an alignment.
