It will be difficult for that size. Second point, you can't use disc probe in RDS.

[Ri...] Posted January 13, 2021 Share Posted January 13, 2021 You have an RDS, build an L probe, and measure it in 4 positions. Link to comment https://qualityforum.zeiss.com/topic/13724-disc-probe/#findComment-70612 Share on other sites More sharing options...

I would use a symmetry point (from each side of groove) in a formula to locate circle in the center of groove width. It is also possible to use a larger probe and self center strategy on the groove to locate center.

[Ri...] Posted January 13, 2021 Share Posted January 13, 2021 My goal is to convert everyone to not use Disc Probes at some point in my career. Lol. Link to comment https://qualityforum.zeiss.com/topic/13724-disc-probe/#findComment-70620 Share on other sites More sharing options...

They asked me about how to calibrate cylindrical probe. They don't know how to calibrate it!!!.

[Ri...] Posted January 13, 2021 Share Posted January 13, 2021 Cylinder probes are great for sheet metal, or trying to capture thin edges. The biggest problem is that you have no guarantee that the cylinder probe is perpendicular to the surface, and so when you are measuring a feature you don't know if you are hitting on the area where it is qualified to. If you have huge tolerances, it doesn't matter though. Link to comment https://qualityforum.zeiss.com/topic/13724-disc-probe/#findComment-70624 Share on other sites More sharing options...

It is better to create a t or star probe which will give you the option to measure form, size, and location of a groove. You are extremely limited to what you can do with a disc probe, and the setup is a pain in the butt. Not worth it. Once again, this is my own opinion. I've measured a wide array of parts from various industries, and I've still yet to encounter an application where I just had to have a disc probe. I'm sure there is one out there, but I've yet to see it. Link to comment https://qualityforum.zeiss.com/topic/13724-disc-probe/#findComment-70628 Share on other sites More sharing options...
[Ow...] Posted January 13, 2021 Share Posted January 13, 2021 I use disk's more than I'd like to but, sometimes it's the most fea$ible. The system pictured took a lot of work (trial and error) weighing, measuring and compensating with gage correction qualification to get the results/variation I wanted but, I got it within 0.002mm of what I'd get with a shorter dynamic tensor qualified probe. Had to slow it way down and up the measuring force (mN) to 500 to subdue noise/chatter. A hollow half Hemisphere would have been better but the cost of a special made one was a prohibitive NO.
