@nitishpande377 3 года назад

This is the 3rd time I am watching this excellent video by you. I am always amazed by the way you show with an example that how 1 can look into the dimensioning & tolerancing scheme, to check if we are allowing too much variation at assembly. Excellent & crisp explanation Kevin ji with an apt example. It is a thought process & not just simple drafting a 2D drawing.

Actually all the spacers of 4.2~5.8 will not fit in slot of dimension 4.4~5.6😀

@Halchal_America 2 года назад

I believe if Min of groove is 5.8 then and then all the spacers will be fit in slot which means we need to correct the overall mean from 5 to 6 and if the parts are legacy then we need to tightned their overall toleraces from 0.6 to 0.1 then all the spacers will fit. Correct me if I am wrong.

@karti9229 2 года назад

When the slot is at 5.8 won't fit in 5.6 gap

@SMS-gn6hn 9 месяцев назад

For 5.8 : 5.6 is interference fit For 4.4 : 4.2 is clearance. So spacer dimension must be based on which fit do you need to plan in both lower and upper case.. If we need correct dimension fit then spacer dimension tolerance need to modify i.e 5 +/- 0.6

@pravasdhar5342 8 месяцев назад

In wrost case spacer may not able to fit because spacer max dimension is 5.8 and we have max clearance in bolt is 5.6 so in wrost case we can't fit the spacer or we have interference fit of 0.2 mm so for wrost case we need to modify the spacer dimension as our bolt is legacy

Suppose if M or L modifier is given on feature dimension then do we need to calculate VC and RC for the same for stack up analysis?

@mudabbirmirkhan1372 3 года назад

I have a doubt, if the spacer comes at USL i.e. 5.8 mm how will it fit in the groove of max dimn. 5.6 mm??

@mechanicalvault 3 года назад

Yes, you are right. Max dimension of groove has to be more than 5.8 in order to fit the spacer. This will drive change in stack up chain dimension or tolerance so that it meets the requirements since current dimensioning chain is not meeting the requirement.

@Halchal_America 2 года назад

@sandeshmahaladkar6020 6 месяцев назад

Actually the spacer width can vary from 4.2 to 5.8, but the gap is varying from 4.4 to 5.6. So basically the gap is less than the spacer and we cannot fit the spacer in the groove. But in video you are telling we can fit it.

@vasudevbhise2549 3 года назад

Could you please suggest best book for tolerance stack up analysis to understand in depth.

@prakashdeshpande8785 2 года назад

In my opinion, you have taken a very simple looking illustrative case which can be solved orally within half a minute. The mentioned tolerances on the three dimensions can be directly added to +/_ 0.6 Can you illustrate a little complex case where the individual tolerances are not equally disposed bi-lateral ones, but with a mixed variety of un-equally disposed bi-lateral tolerances, uni-lateral tolerances etc.

@mechanicalvault 2 года назад

In the case of unequal bilateral or unilateral tolerances, you have to convert it into equal bilateral for the analysis and then remaining process remains exactly same as I explained in this video.

@helpmeimconfused 3 года назад

How did you get 5 as the mean of the sum of 45 and 40 mm? wouldn't the mean be 42.5 mm? isn't that just the difference between the sum of both positive and negative directions?

@mechanicalvault 3 года назад

This mean is the mean of the clearance between positive and negative values because we are interested into the clearance and it's variation.

@helpmeimconfused 3 года назад

@@mechanicalvault It doesn't make sense (to me at least) to call it the mean when you didn't do (45 + (-40))/2, which is the mean equation for two values. What you did was 45 + (-40). Wouldn't that be the nominal size if it was a perfectly made part without tolerance and not the average size if it was a perfectly made part?

@mechanicalvault 3 года назад

Looks like you need to sit with someone experienced and understand the concept of Stackup analysis. Here we are not talking about the dimension average, we are talking about the mean of the gap and then we apply tolerance value to get extreme limits.

@helpmeimconfused 3 года назад

@@mechanicalvault yes I do, that's why I searched videos on the topic. How do you think I ended up finding this video? I'm confused on why you're saying "mean". You say we're not finding the average dimension but the mean of the gap. But "mean" means average in math. www.mathsisfun.com/definitions/mean.html You're saying we're not finding the average but then you put "mean" in the video but you found the "mean" in the video by doing 45 + (-40) which isn't how you find the mean. Does "mean" just mean something else? And being a snarky asshole when I'm asking a question trying to understand the video isn't the way to go. Yes, I need more experience that's why I'm watching RU-vid vids on the topic. I wonder how having you as a professor is like -- students can't ask questions in class without being attacked. 👍.

@michaelscarn4133 3 года назад

@@helpmeimconfused that is correct, his explanation is wrong, mean is 42.5 and you calculate the sigma value of each dimension and then calculate the min/max overall dimension to fit the spacer

are you kidding? how come that spacer with worst condition of 5.8 will fit in worst condition of 4.4 mm gap? Your video was very good in explaining stackup but end screwed everything
