[Zo...] Posted October 9, 2024 Share Posted October 9, 2024 I have this super simple part and measurement, but as it is often the case, cannot get it going because of the base alignment. All I am interested is a R 0.01 radius measurement on the top of a cone on a 0.250 rod. I thought I could use the top for space rotation with Z+, no planar, the rod diameter for X and Y, and the top again for Z. I plan to use a 0.5 mm stylus in the right horizontal (#3) position. Can someone tell me why it isn't accepted by Calypso? And what would work? I tried many variations... to no avail.

[To...] Posted October 9, 2024 Share Posted October 9, 2024 The Spatial must be a feature capable of controlling 2 axes of rotation. Since a circle is a 2d feature, it cannot. How about a cylinder from the OD, and maybe a point on top for Z Link to comment https://qualityforum.zeiss.com/topic/4650-radius-on-top-of-a-cone/#findComment-14410 Share on other sites More sharing options...

That might help if the sphere is not in-line with the cylinder.

Point is also a 2d feature so it can't be used for spatial Link to comment https://qualityforum.zeiss.com/topic/4650-radius-on-top-of-a-cone/#findComment-14420 Share on other sites More sharing options...

It wants to go to the right and approach from there, but naturally runs into obstacles. My clearance plan is Z+, but still goes to the right. Any idea what I do wrong? here is a video of the move: https://share.icloud.com/photos/09e_UFO ... eR_MYrZ2OA Link to comment https://qualityforum.zeiss.com/topic/4650-radius-on-top-of-a-cone/#findComment-14422 Share on other sites More sharing options...
[Cl...] Posted October 9, 2024 Share Posted October 9, 2024 Use the cylinder OD as XY zero and spatial. Measure 2 equally spaced lines up opposite sides of the cone. Intersect them. Use that intersection (Point) as Z zero in a secondary alignment (XYZ). Assign that alignment to the tip sphere/radius. Now the probe should hit the target spot on.

[Zo...] Posted October 10, 2024 Author Share Posted October 10, 2024 Please sign in to view this quote. the photo shows the bad move, it is approaching from the wrong position even though the base alignment seems to be accepted, somehow it cannot find the part.bad move.PNGpoint2.JPGpoint1.JPGcyl.JPGBA.JPG Link to comment https://qualityforum.zeiss.com/topic/4650-radius-on-top-of-a-cone/#findComment-14428 Share on other sites More sharing options...
[Cl...] Posted October 10, 2024 Share Posted October 10, 2024 I would use a straight down (Z-) stylus to measure the tip, You'll be able to measure a larger radius. I'd measure it as a sphere using probing points as opposed to scanning it. I'd also suggest and constraining XY&Z Link to comment https://qualityforum.zeiss.com/topic/4650-radius-on-top-of-a-cone/#findComment-14430 Share on other sites More sharing options...

Once the probe goes directly to the feature, I can change or manipulate the strategies, but it has to recognize the part location first, and I don't know why it doesn't Link to comment https://qualityforum.zeiss.com/topic/4650-radius-on-top-of-a-cone/#findComment-14440 Share on other sites More sharing options...

By the way, I do use the 3mm down probe for the point on the top, and planned to use a .5 mm #3 right probe to scan the radius but I can try the 3mm down probe to touch off the radius, once it finds it and "goes" there Link to comment https://qualityforum.zeiss.com/topic/4650-radius-on-top-of-a-cone/#findComment-14442 Share on other sites More sharing options...
[Ow...] Posted October 10, 2024 Share Posted October 10, 2024 Are sure you have the correct probe assigned to the point? The screen shot shows the 3mm down probe assigned and that isn't a 3mm probe. Go to the measurement plan editor and choose "Stylus" and take a screen shot of the probes assigned with the clearance group assigned beside it, that may help show the problem.

I changed the R0.01 probe from 0.5mm #3 to the 3mm #1 and from scan to touch probing, but didn't make any difference, because "finding" the part seems to be the issuestylus+clrnc.JPG Link to comment https://qualityforum.zeiss.com/topic/4650-radius-on-top-of-a-cone/#findComment-14446 Share on other sites More sharing options...

I would go to Resources > Utilities > Set Base Alignment to Zero. Then run a manual alignment.
