[Je...] Posted July 14, 2022 Share Posted July 14, 2022 . Do you think it's feasible to measure this .005" radius on a torus using a 0.2mm ruby? Is it a fool's errand? Any suggestions or strategies? . . Link to comment https://qualityforum.zeiss.com/topic/9970-can-i-measure-this-005quot-radius/ Share on other sites More sharing options...

Otherwise, maybe, but is going to be hard. Link to comment https://qualityforum.zeiss.com/topic/9970-can-i-measure-this-005quot-radius/#findComment-47372 Share on other sites More sharing options...

[To...] Posted July 15, 2022 Share Posted July 15, 2022 Why stress yourself out. Check it or the tool radius on a comparator Link to comment https://qualityforum.zeiss.com/topic/9970-can-i-measure-this-005quot-radius/#findComment-47376 Share on other sites More sharing options...
[Je...] Posted July 15, 2022 Author Share Posted July 15, 2022 . I was assigned to measure it and report as is for a new product investigation. It is a stamped stainless steel part. There is no tolerance assigned. Unfortunately we don't have a comparator, and the tooling is in production. I'll give this a shot, and if it seems to not be feasible, I'll just let the engineer know. I like trying the difficult to measure stuff. It's most of what I do. Test the limits. I probably should have been an experimental test pilot or something edgy like that. .

[Ro...] Posted July 15, 2022 Share Posted July 15, 2022 Do you have a Calibrated Eyeball anywhere in the shop? I say not possible, but if you were to try id suggest taking 5 points and not a scan.

[Da...] Posted July 15, 2022 Share Posted July 15, 2022 You could make a mold of it and then check that. It would be an O.D. so clearance would be less of an issue.

Could go, but I'm thinking of spring back effect compensation -> https://www.machinemfg.com/stainless-st ... pringback/ Well, maybe it wouldn't be seen on such small dimensions.

[Je...] Posted July 19, 2022 Author Share Posted July 19, 2022 . Hi. Just following up on how this experiment went. I'd give it a B+. The first few samples were slightly warped, which made capturing the .005" radii difficult. The remaining samples were doable, aided by the fact that there was a slight draft to the side walls. The limiting factor was that the actual size of the probe is .004065, so if the actual radius is smaller than the probe, it won't capture correctly. I created curve sections and then recalled points from the radius areas into circle features. . . . .

The engineer wanted to troubleshoot a problem, so we needed more specific data. .
