@4:27 According to GDNT tolerance where we are positioning co-relatedly GDNT rule 1 or rule 2 may apply i think

Hi, Master Ayush, I have a question: hope you can help me understand it clearly in the video, you says Rule #1 can be overridden by Rule #2 ONLY in THREE ways - applying flatness tolerance to the dimension of a planner... AME = 11+0.5=11.5 - by applying a straightness tolerance to the size of a cylindrical ... - by specifying the independence symbol "I circle" But before these content, you also said/showed(at 14:33) that applying a flatness(and also other geometric tolerance) to the surface of a feature of size(a shaft, not to the size of the shaft), it follows regardless of feature of size(geometric tolerance independent from size limit), the AME = 11+0.5=11.5, and Rule #2 definitions says when no modifier is defined the RFS applies. So this makes me confused why we say "Rule #1 be overridden by Rule #2 ONLY IN THREE WAYS", it seems not only three ways where Rule #1 is overridden?

Hi, yes this is bit confusing but, I hope this will help you. 1. Most of the time both rule works together, Rule 1, ensure part should be under defined limit size, should be under envelope size, example 10 +-1 mm, part should be under maximum 11 mm, and minimum 9 mm. and Rule 2, say that part geometric variation (flatness, straightness, circularity, etc.) are independent of size variation, if MMC or LMC is not defined in feature control frame. 2. But this gets little complicated when we get closer to MMC or LMC, for example, if part is manufactured at 10 mm (actual size through the length). then there can be 0.5 mm flatness (bend) so envelope size would be 10 + 0.5 = 10.5, which is in the range of size tolerance (9 to 11) that completely fine. but let say if part is produced at MMC, 11 mm. (actual size through the length) then the part should not be bend, flatness has to zero. here. (if flatness is applied to surface) otherwise part will cross the envelope size limit (11) and this is why, we say GD&T rule 1 - perfect form at MMC. 3. so in this case GD&T rule 2 getting overridden by Rule 1. not Rule 1 is overridden by Rule 2. Rule 1 can be overridden only in three ways, already explained, i hope this will help.

Please make a video on advance level of assembly If we change the dimensions of any one or more components who are assembled then how we can do changes in fast and in effective way

The video you made is very useful. I have a small suggestion about the display time of images as well as calculation formulas. It is too short, sometimes faster than the speed you speak, leading to viewers not having time to visualize the problem you are talking about. Sometimes I have to stop the video to take notes, it affects the continuity of the lesson. If possible, please increase the display time more. Thank you very much

First, Thank you so much for your video. I have some questions. There are 3 ways to override rule #1. set flatness(RFS) to DMP, set straightness(RFS) to dml or put "I" symbol. In these ways, we evaluate dimensions and gd&t seperately 1. What will happen if I put circularity or cylindericity? rule#1 will be ignored? about flatness(Not DML) and straightness(Not DML), you mentioned in this video. 2. what about MMC(LMC), MMB(LMB) modifier? I thought they are also the ways to override rule#1. Are these also one way to override rule #1?

@mastermechanicaldesign 3 ай бұрын

About GD&T Rule 1 Circularity and cylindericity is surface control. We can't apply to the size dimensions. Also we can't apply MMC or LMC to these controls. And these controls can't override rule 1. Let say we apply 0.1 mm cylindericity. It means shaft cylindcity should be between 0 to 0.1 mm. And when shaf will be at MMC, circularity has be 0. Perfect form at MMC.

@jameschun311 3 ай бұрын

@@mastermechanicaldesign then all form control can't override rule #1 except the specific situation like flatness to DMP, set straightness to DML? because there are applied to size dimentions?

@mastermechanicaldesign 3 ай бұрын

Yes, only in these conditions when a flatness or a straightness tolerance is applied to a size of a "feature of size," GD&T rule 1 overridden. But not because, only these tolerances can apply to size dimension. For example, perpendicularity can be also applied to size of a "feature of size" but GD&T rule 1 not get overridden, because perpendicularly controls orientation does not form of feature of size. I would suggest you watch from chapter 1.
