One of d Great channel to learn engineering design and who don't have much more money to go into class and paid in lakh that aspirants I suggest this is place where u can learn all about engineering design 100%
Very interesting sir.i have a doubt ,in this drafting specifying modifier to secondary and tertiary datum, but in other cases only in primary datum only showing.actually how is depending on the assembly.please give me answer sir.
Hello Sir Gratitude for the valuable information, Sir I have some doubts as a design engineer did we need to calculate all tolerances, how to select which standard is required
Company will decide which standard they will follow, but we need to mention it in Drawing. We generally use old drawings or general tolerance ISO or IS for most dimensions. We do stackup or mfg process Capability study only for functionally critical dimensions.
@@mechanicalvault Thanks for your answer Sir I'm interested in design, so I started my in reverse engineering now I'm near to 2 years, I'm switching to design engineer in interviews whenever it comes to GD&T we are not familiar with it much but theoretically I'm learning from online flatforms, I watched Top skills for design engineer video one of yours and based on that I'm preparing Can you suggest me how I can switch and what is your opinion on reverse engineering. Thanks in advance for your answer and time to read my reply
Angularity value is dependent on angle of the feature???? It is measured by sinbar techniqe, if angle got deviation,the angularity is also deviate, is that both having relationship..
Angularity TOL is defined by 2 parallel planes inside the size tolerance zone in which all surface elements of the angular surface lie. If angularity TOL is not mentioned in the drawing, size tolerance controls angularity indirectly. It's only when we need tighter control between two angular surfaces, we can use Angularity TOL.
Bhaskar Reddy - It depends upon function and how part is assembled on next level part to decide if we need one, two or three datums. Apart from FORM symbols in GD&T, we need at least one Primary datum minimum. But if our part is located with respect to additional one or two planer or non-planer datums, then we may have to use secondary and tertiary datums as well.
So helpful Can you prefer good book for GD and T and also If you wrote any books related to GD & T then please let me know Thank you so much for this video
There is no second word about your lecture your lecture is awesome I already subscribed your channel along with that I would like to have a book because it will easy to brush up during Interview time So please suggest me It's my Kind request to you
Kevin San Your lecture was awesome and I want to learn everything about gd and T please suggest me the best book for GD& T and give me the PDF version bof this Video
At 3.38 timeline MMB is 12.05 because the diameter has Dia modifier means the perpendicularity should in dia of 0.1 Radius of 0.05 And the other diameter is 7.5 not 7.3 You are not consider the Diameter modifier
Please why is 7.7 - 0.4 MMC not MMB as the first 2 calculations at the beginning of the video? I have rewatched several times why its not MMB? Edit: I understand it now
Very good sir , but please stop using background Music, its not good. Concentration is disturbed. If i put headphones the music is irritating. 🙏🙏 Kindly work on it.
MMC is the maximum size of external feature of size and minimum size of internal FOS (where it has maximum material on it). When we apply geometric tol at MMC, we get virtual condition which is combined effect of MMC and Geometric tolerance. As actual produced size departs from MMC towards LMC, it provides equivalent bonus tolerance. MMB is the Virtual condition at datum if M modifier is used besides datum reference in feature control frame.

Thank you Ganesh!!
after watching multiple videos i found this is the best one, explained at ground level. thank you
I m there in linkdin and looking following your videos..great...
thnak you very much for the information sir Kevin...god blesss
Thabk you 😊
Glad that you liked the video!
Nice content looking forward
Thank you, Anil!
Very good and simplified explanation :-) Keep up good work.
Thank you so much!
Good Content
your videos are very much helpful thank you. can you please make a video showing what is the difference between GD&T ASME and ISO GPS
nicely explained
Hello Sir,
Why we Subtract tolerance in MMC and Add tolerance in LMC Condition
Very interesting sir.i have a doubt ,in this drafting specifying modifier to secondary and tertiary datum, but in other cases only in primary datum only showing.actually how is depending on the assembly.please give me answer sir.
Please create more videos related to design calculations...
Great video thanks for your efforts
Glad that you liked it :-)
calculating projected tolerance symbol in case washer is present in the assembly? Should we take washer height into consideration?
Yes, because now bolt has to pass through washer and still clear the part which is sitting on top.

Can you suggest me how I can switch and what is your opinion on reverse engineering.

Sir please make a vedio on ' How To calculate the Geometric Tolerance Value
Good 1
Thank you!
Sir, I have I doubt what is the difference between concentricity & radial run out ( measurement methods)
Excellent
Glad that you liked it :-)
Sir kindly make an video on Young's modulus, bulk modulus, modulus of rigidity, poison's ratio
sure, Pavan; Thank for your input;

sir,
at 6:03 what is the significance of LMB ie, 12.3 value, while we are drilling 7.7-8.5(LMC) dia hole?
In drawings are we following this much?
LMB results into datum shift which plays the role when we have to adjust the part in assembly for function or mesurement.
Sir i have one doubt in datums pls solve me. In rectangular box one datums is sufficient? We are using 3 datums.
Bhaskar Reddy - It depends upon function and how part is assembled on next level part to decide if we need one, two or three datums. Apart from FORM symbols in GD&T, we need at least one Primary datum minimum. But if our part is located with respect to additional one or two planer or non-planer datums, then we may have to use secondary and tertiary datums as well.

Please make a vedio in hindi

I am soon launching online course of GD&T and stack up analysis course; so keep track :-)
There is no second word about your lecture your lecture is awesome I already subscribed your channel along with that I would like to have a book because it will easy to brush up during Interview time So please suggest me It's my Kind request to you
I hope you understand my intention please suggest me
@@mechanicalvault
If you wrote any books or PDF then please provide it will help during Interview time to brush up
Go through ASME Y14.5-2018 standard which might be available in your organization.
This is helpfully
Glad that you liked it!
Did not explained the interpretation of P modifier. Can u explain or refer if any other video available for it.
Looks like you did not watch complete video.
P modifier is explained in details. It start from Min 7.0
Thanks for the content. please reduce or remove the background music
Thank you for the feedback; I will consider it when I upload my next video!
Tqs sir .
Can you please remove baground music
Can't remove in this video, but have stopped using it in new videos based upon feedbacks 😇
Kevin San Your lecture was awesome and I want to learn everything about gd and T please suggest me the best book for GD& T and give me the PDF version bof this Video
I will suggest to go through the standard of ASME Y14.5-2018 which might be available in your company.
At 3.38 timeline MMB is 12.05 because the diameter has Dia modifier means the perpendicularity should in dia of 0.1 Radius of 0.05

Very good sir , but please stop using background Music, its not good. Concentration is disturbed. If i put headphones the music is irritating. 🙏🙏 Kindly work on it.
Thanks for your suggestion!
I will definately find out the way out.
music in background irritation sometimes sir
It's old video. Stopped adding background music in new videos!
hello sir ,sorry but you have illustrated maximum material condition in wrong way as we get bonus tolerance if the part is drilled or machined at mmc.
MMC is the maximum size of external feature of size and minimum size of internal FOS (where it has maximum material on it).
When we apply geometric tol at MMC, we get virtual condition which is combined effect of MMC and Geometric tolerance.
As actual produced size departs from MMC towards LMC, it provides equivalent bonus tolerance.
MMB is the Virtual condition at datum if M modifier is used besides datum reference in feature control frame.
Also, if we use M modifier, we get zero bonus tolerance when part is produced at MMC. Kindly re-check your statement again.
