[Lo...] Posted January 12, 2023 Share Posted January 12, 2023 Hello everyone, So I have a bearing race and I need to measure the diameter. I have my base alignment set and the program works good, except when I try to measure the torus. The probe moves to the side of the race, probes upwards then causes a collision at the top edge. I have no experience measuring a torus (obviously) and could use some assistance. I attached a picture of what I am measuring. Thank you!Capture.PNG Link to comment Share on other sites More sharing options...
[To...] Posted January 12, 2023 Share Posted January 12, 2023 Open the Torus feature and double-check ID/OD switch next to Name field. Link to comment Share on other sites More sharing options...
[Lo...] Posted January 12, 2023 Author Share Posted January 12, 2023 Thanks Tom. Double checked ID/OD switch changed it ID, I am using the Large Circle Path strategy. And now it touches the top outside edge and heads south on Y and down on Z then errors out with a collision......... 😕 Link to comment Share on other sites More sharing options...
[Ke...] Posted January 12, 2023 Share Posted January 12, 2023 You may need to reduce your clearance distance? If you just need the bearing race diameter, but don't want to deal with the torus headache, try: Measuring the torus location by constructing a circle at 1 location on the torus. Then measure the race diameter using another circle at the the reference circle height (Use secondary alignment or a formula in the feature) ...you can use a self centering method for the race diameter if you want, but it shouldnt be necessary.

[Ch...] Posted January 13, 2023 Share Posted January 13, 2023 Lou, Toruses or tori have a clearance zone pretty much the shape of the donut. I've experienced what you are seeing when initally working with them. I'd recommend 0.0 clearance distance, definetly watch ID/OD switch. Also try to see on the model where the nominal path is supposed to start to make sure. I also now have a ton of experience measuring ball races. Good luck.

[Lo...] Posted January 13, 2023 Author Share Posted January 13, 2023 Thanks everyone. So I was able to get the diameter. I adjusted the Start Angle and Range Angle. I noticed the lines were outside the of the feature, so I just tried moving them in and it work great. But I am trying to get the radius, I can only get it if I do a manual circle. And I am also trying to get the dimension form bottom of the radius to bottom of the part or bottom plane. And all it's doing is crashing the probe hard, hard enough to break....Ooops. Sorry boss!Circle path.PNGFeature.PNG Link to comment Share on other sites More sharing options...
[To...] Posted January 13, 2023 Share Posted January 13, 2023 Please sign in to view this quote. Use "Define Circle on Cylinder". Click on the surface of the torus. You'll be prompted with choice for Main Radius or Subsidiary Radius. Choose Subsidiary Radius and it will create a circle right where you clicked. Double-check the ID/OD of this circle.

[Lo...] Posted January 13, 2023 Author Share Posted January 13, 2023 Thanks Tom, I tried that and all the probe keeps doing traveling away from the part and creates a collision. I did however just by accident inspect the radius. Size, More, Radius2 and it work.... Now I need to get the distance from the radius to bottom of the part. Thanks!!!!

It works, but it's measuring the radius of the whole circle. I'm looking for the ball diameter or radius. I tried for awhile Friday afternoon, I could get it manually but not using CAD feature. Thanks! Link to comment Share on other sites More sharing options...
[Lo...] Posted January 17, 2023 Author Share Posted January 17, 2023 UGH.... Ok so I just figured out the ball radius. Size-More-Radius 2 and selected Torus as the feature. Now distance from the bottom of the radius to the bottom of the part. I'm getting there......... 🤣 Link to comment Share on other sites More sharing options...
[To...] Posted January 17, 2023 Share Posted January 17, 2023 Please sign in to view this quote. Did you select subsidiary radius? Link to comment Share on other sites More sharing options...
[Lo...] Posted January 18, 2023 Author Share Posted January 18, 2023 Please sign in to view this quote. Yes, I was able to get the dimensions I was looking for! I appreciate all the info! Thanks! Link to comment Share on other sites More sharing options...
