Actually Flatness is checked wrong, part needs to be on three points above the surface plate, (like gauge or 1-2-3 blocks) otherwise you are checking parallelism to the surface plate because you are fully resting the part on the surface plate. See the GD& T Y14.5-2018 specifications for proper setup of flatness. I usually test this on the underside first with a dial test indicator and then the top to check both surfaces for flatness in my metrology lab. Several mistakes here, including measuring perpendicularity, dial indicator has to be 90 degrees to the part, no angles allowed otherwise cosine error.
This video made my day! Thank you so much for creating this video... this is the best teaching tool I have ever seen... Reading from a book does not teach everything... Please make more videos to show different ways of all 14 basic measurements...
at slide 2:30, if the dial bore gauge is at a different angle, isn't it measuring the "hypotenuse" length variation? shouldn't the dial gauge mounted horizontally?
You are right!!! also when they are triying to measure cylindricity is in that way, cilindricity is a 3D dimension and in internal measure, not external, they are measuring total runout.
Finally a video that shows how to actually take these measurements. To the point! Thank you!

Yes

@@dac1m5 need to read carefully,
Cylindricity is measuring the form tolerance, Total Runout is measuring the runout tolerance. GG
Just wonderful… really makes a lot sense…. Great video
Best video i ever seen thank you
Awesome learnt GD & T well😄
Nice Video
Mind blowing 😮
Great video!
Amazing 👍
Great ji
Nice explain thanks
thank you sir
Thanks for the video , but i think at 0.54 you are checking parallelism not flatness .
Yes this is parallelism check not flatness at this point in the video.
very helpful
Need more explaination about realtime checking methods ,pleaseake a one vidio realtime actual method by your hand if possible...tqfor great vidio
Good
👍
Need to be slow and brief details .. please hurry...

How to check internal dia with this dial ?
Hi it is verry nice. Can you Give me the parts and assembly for Inventor or step or Solidworks pleace
I missed model.
When I found I will sent
Able to learn fastly than reading from a books
14 Symbol Insument name
Give pdf on link for study more & procedure
Tell me
Concentricity missing 🤔
Circularity AND Concentricity 2:09
Need explanation....otherwise this video is not worth
😂😂
Good
