Hello Dean.. Thanks so much for these videos, subscribed at the very first video that I watched.. These are just precious.. It would be really helpful if you can do a video of measuring / inspecting samples for all these three controls (Position, Two single segments and Composite)
Hi, thanks for the comment. That’s a great suggestion, and I will make a video about it someday. For now, I’d like to mention that the inspection is actually the same, as far as the instruments and methods. It is the interpretation of that data that changes. For a composite position, if the lower segment tolerance is met to the upper segment datums, the work is done. If not, there data needs to be analyzed further.
Yes, it is on my list of videos to make. Let me see if I can get something out this month on the topic. Thank you for the suggestion. I often choose topics at random, I would prefer to do topics that people actually want to see.
@@RDeanOdell Thank you for your understanding and your time. This is very useful content not only for me. I think that with the rest of the video materials, I will remember if they are critical topics for me. In Europe, it is difficult to find such knowledge without incurring financial costs. Standard Calypso basic and advanced training at Zeiss does not make it clear. Usually 1-2 simple cases are discussed ... I had a trainer who was overshadowed by the pattern of holes :) I am waiting anxiously for the next ones :)
Thanks so much for your GD&T videos. Really useful. I have an query regarding “Composite vs Two Single Segment” Positions. I can Cleary understand the difference between composite Vs two single segment position from your video if its two datum’s in below segment. But I couldn’t able understand the difference, if its only one datum in the below segment . What’s the difference between composite Vs two single segment position if its one planar datum in below segment? Can you able to clarify with some examples or videos? It will be helpful.
Azating content, I was able to find an error in the measurement process for a part validation in my work, they were measuring the part as if it were defined with a composite feature control frame, when it was a two single segment.
Hi Dean-Thanks for these videos…seeing as everybody else is requesting videos, could you do a video(or reply) to see if combing linear dims and positional tolerances is legal in y14.5m 1994? I’ve seen a few drawings with linear dims controlling ‘x’ position for example but ‘y’ is controlled using position. Some examples include slots in faces or lugs welded onto a part…thanks again 😁
Thanks for the great question! The short answer is that the method you mention, using plus-minus dimensions with position tolerances, is not allowed in ASME Y14.5M-1994. It was allowed in the 1973 ANSI standard and the older MIL-STD-8 standards so it is possible to see it on drawings for sure. I am working on a video to address the topic in more detail.
Hi, I made a video about your question. I’ll make it public next week, but here is the link to the unlisted version. Thanks for the great question. GD&T: Position Tolerance Without Basic Dimensions? th-cam.com/video/GnNTzeBu25k/w-d-xo.html
Sir, in composite position tolerance, what is the difference between in bottom frame, with and without mentioning datum B,how it is rotating ,only rotating either side by .015
Tank you for this explanation. Its different to what we know in Europe acc to ISO spec. Question.. in the second example the smaler circles (tolerace zones representing lower FCF) are scattered left and right in the bigger circres. Does not the lower FCF control pattern of holes?
It is true that we have ISO in Europe. However, many companies, especially automotive and aviation companies, work with the ASME standard. I don't know about Western Europe but it is quite common in Eastern Europe.
Am I correct in understanding that the composite FRTFZ refinement of orientation to A and B restricts the movement of the pattern parallel to B, but in the MSS positional. The smaller segment zone floats individually to the the other zones while restricted to movement from B? Also I noticed when you introduced the composite you accident said profile versus position.
“Composit Position” appears to be meaningless when the part is completely fixed in the assembled state and cannot move or rotate at all. So, is “composit position” used when parts can move or rotate slightly in the assembled state? I am curious in what cases “composit position” is applied to part drawings.

@@RDeanOdell Thank you Dean!
Please. We would like to see how to apply these on the software. Thanks for sharing and teaching these online.
@@RDeanOdellthanks for the video
, could you please make a video on that
Great explanation sir ❤ ......got clarity of all doubt..........from India
Is there a chance for a video presentation on how to do it correctly in Zeiss Calypso?
Yes, it is on my list of videos to make. Let me see if I can get something out this month on the topic. Thank you for the suggestion. I often choose topics at random, I would prefer to do topics that people actually want to see.

@@RDeanOdell Please, please. Thanks Mr. Odell!
Thanks for Videos Dean. Have you had a change to make Zeiss Calypso video for this lesson?
You are amazinggggg!!!
Thanks!
Valuable videos, thanks
Thank you for watching, glad you find my content useful.
thank you sir , for ur all such important videos ... really so helpful for me
Great to hear! Thanks for watching and commenting.

Hi, Great question! I'm editing a video now that will address it in some detail. Look for it next week.
Thank you sir. Really so helpful 🙏God bless

That’s really great information. Thanks for sharing.
Please explain composite position for round parts for example clock od datum and face datum..
How to calculate position when given composite feature control frame.
What if your location datum is a diameter or hole center / axis. Relationship still the same with composite?
In example 3, how do you measure this? Do you align through the hole pattern and measure to themselves at 1.00 ?
Thank you sir!
You’re welcome. Thanks for tuning in.
Hai sir .. please explain True position in MMC condition in calypso
Am I correct in understanding that the composite FRTFZ refinement of orientation to A and B restricts the movement of the pattern parallel to B, but in the MSS positional. The smaller segment zone floats individually to the the other zones while restricted to movement from B?
Also I noticed when you introduced the composite you accident said profile versus position.
Good work!

“Composit Position” appears to be meaningless when the part is completely fixed in the assembled state and cannot move or rotate at all.
So, is “composit position” used when parts can move or rotate slightly in the assembled state?
I am curious in what cases “composit position” is applied to part drawings.
i have some question
could i have your gmail?
Sure, you can look it up on the “about” page of my TH-cam channel.
