Are the two tangental lines that are in contact with the V block really sufficient to model the full surface of the cylinder for measurement? I assume you would need a longer V block for a longer part to ensure that the shaft doesn't fall out of tolerance on account of a lack of straightness, right? Because you're relying on the rotation though this seems like you're measuring total runout and not actual cylindricity. Stumbled upon your video because I'm struggling to understand the circumstances under which one would use cylindricity as opposed to total runout so anything you can provide to help me understand better what you're actually measuring here will be a big help. Thanks.
Hi every one. if the method taht you are using to measure is for cilindricity, then what is the purpose of these symbols for total runout? in my opinion the cilindricity symbol is exclusively for the internal diameters, because there is roundness, runout and total runout for the outer diameters measurments.

Thanks for illustrative video.
nice explanation with demo.Thanks
Thanks. This was helpful.

My professor told that cylindricity is measured by holding the shaft at the centre and not cylindrical surface
