In the last exemple you talk about cylinder datum feature with runout specified on it. How to inspect runout of cylinder referred to its own axis? Ofcourse in mathematical way it is obvious, but durring inspection you have to simulate the datum by collet or chuck. Because of that dial indicator has no access to surface. How to inspect such requirement on real component? Way to simulate datum and keep access to surface is by V-block, but v-block simulates datum based on two edge contact and simulated axes can vary during full indication movement. Is there any bether way to simulate datum and keep access to surface?
In my opinion it should at the very least have a CF identifier because it is possible to chuck it up on just one end. Preferred method I think is using both datum A thru datum B to be absolutely clear.
Hi, I prefer identifying each feature as a separate datum in this situation. I think it makes it more readable, especially for those that are not hip to the CF symbol.
@@RDeanOdell Hi dean, I am starting working with metal from total minus cero, on my own.., I am finding your tutorials so cool, your transmission of the information is so exactly on point, concise and right to question of matter, no distractions and no fancy yutber videomakerthingys, no tinsulting the intelligence of the viewer, I would have to go to university for this knowledge, I am only missing if your graphics would be a little bit more rigorous, think that the reason for many people to "fail` at technical stuffs, has also a lot of to do with how each person develope their perception of reality, majority of humans do it through the eyes....reasons why videomaking has broken all the rules.., as an illustrator myself what can I say, just to mean, use a bit more the all the visual aspects that a mainly visual platform like youtube has, just some more rigorous drawings and you have it perfect
Thank you sir!
You are welcome!
