Everything about GD&T Rule 1 and Rule 2 [YOU DON'T KNOW]

[@abhishekyash6118]

Thank you for the wonderful concept sir😊. It'll make a difference.

[@Ranjityadav20018]

Now i can say Aayush sir your videos are one of the best and simply understanding videos . I will see your all videos. I m From Nepal .

[@charlestoneoyoo]

Wonderful..learnt much from this content

[@jameschun311]

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]

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]

@@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]

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.

Amazing content sir hats off😍😍😍...mind-blowing explanation...

[@mastermechanicaldesign]

Thank you so much 😀

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

[@mastermechanicaldesign]

Hey, thank you so much for point out this, Yes, I'll improve on this.

[@lawrance0207]

Next you will talk about shaft and hole standard. What is g6 and it's standard

[@Sma0701]

Super content

[@sanketthorat942]

Please make video on how to select proper tolerance for hole and shaft basis fit Tolerance like h7 ,js,n7,m6 from table JIS B 0401-1,2(1998)

[@mastermechanicaldesign]

Okay

[@ngohoangthong4712]

Thanks a lot.

[@mastermechanicaldesign]

You welcome 🤗

[@phongnguyenhong8482]

Please make video a bout caculate chain and gears

[@srinivasanv6573]

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

[@Tech_mechnia]

Please make Video on O-rings and it groove size and selection and standard of it.

[@mastermechanicaldesign]

Sure !!

[@IrfanHabib-vf8bn]

When is the next video coming?

[@mastermechanicaldesign]

Today

[@alagumalaikannan7213]

I'm waiting Next video...

[@mastermechanicaldesign]

Coming soon (in editing)

[@lohithm5043]

Both might be correct by specifying a note

[@vishalk9656]

Explain about shock absorber selection

[@mastermechanicaldesign]

Okay. but it's too much complicated
