[Jo...] Posted August 7, 2020 Share Posted August 7, 2020 I have a part(casting) that has a profile callout with an all around designation. Is there a realistic way of doing this with CMM ? That is the only callout on the entire part, all others are Basic. Link to comment https://qualityforum.zeiss.com/topic/14950-profile-all-around/ Share on other sites More sharing options...
[Cl...] Posted August 7, 2020 Share Posted August 7, 2020 Depending on the geometry, free form surface might be an option. Link to comment https://qualityforum.zeiss.com/topic/14950-profile-all-around/#findComment-79606 Share on other sites More sharing options...
[Jo...] Posted August 7, 2020 Author Share Posted August 7, 2020 Please sign in to view this quote. Closest thing I would compare it to is a compressor housing..it has complex geometry, ports, transition areas.. I think the customer is expecting a data cloud. I don't know how else to present the results. Right now I'm trying to determine the point density requirement. I do have Curve, freeform. Any tips ?

Apologies, it is profile of a surface with the "all over" symbol as shown in ASME 14.5-2018 figure 11-10 Link to comment https://qualityforum.zeiss.com/topic/14950-profile-all-around/#findComment-79612 Share on other sites More sharing options...
[Cl...] Posted August 7, 2020 Share Posted August 7, 2020 Without knowing the geometry (shape) it's hard to recommend a good strategy. However, I have had good success sectioning the model and creating several 2d curves and recalling those points into a free from surface.

[Ri...] Posted August 7, 2020 Share Posted August 7, 2020 If you had something like a line scan on an RDS, maybe. This is something that 3d scanners shine doing well. Zeiss has their own that works extremely well. In addition, the GOM Inspect Software is really nice for not only doing all over Profile evaluations, but GD&T.

[Ri...] Posted August 7, 2020 Share Posted August 7, 2020 Please sign in to view this quote. The line scan is a red-light. I do believe that I've heard of either a blue-light coming soon or being available.

Luckily, with our plastic parts, I can afford to measure all the complex GD&T stuff with it.

[Cl...] Posted August 7, 2020 Share Posted August 7, 2020 I think touchless scanning is the future. The CFS (white light) on my O-inspect is super accurate, super fast, even with high point densities.

[Ri...] Posted August 7, 2020 Share Posted August 7, 2020 Please sign in to view this quote. The CFS is great because of the accuracy, but the speed is nowhere near what you can do with a line-scan or something like the T-Scan or Comet. The spot size is just too small.

Is just an "All around" symbol, or are you talking about a note that states unless otherwise specified -some profile of surface tolerance?

[Jo...] Posted August 7, 2020 Author Share Posted August 7, 2020 Please sign in to view this quote. It has a single profile of a surface with the "all over" symbol as shown in ASME 14.5-2018 figure 11-10, also see 11.3.1.5 for methods. This print has the symbol on the elbow of leader. I found the easiest way, is to let Richard do it. lol Link to comment https://qualityforum.zeiss.com/topic/14950-profile-all-around/#findComment-79638 Share on other sites More sharing options...

[Da...] Posted August 10, 2020 Share Posted August 10, 2020 The profile tolerance controls all features. If the profile is called out as .6, then you have a ± .3 for a length or dia. unless there is a max stated on the dia. or a radius. See ASME Y14.5 -2018 page 251 figure 11-6.
