Thank you Evan. I agree with trying to tolerance the part so not only manufacturing can understand it, but inspection as well. Even if it doesn't follow the function exactly, if it makes things downstream easier and we still get a good part, that's what matters.
In general, to elaborate more on...
So even if I remove the runout tolerance and just have profile, I cannot use the cone as a datum? I'm thinking something similar to the attached picture, just with the hole moved to the flat face and along the...
I can see how Bonus was misleading, it was just the best word to try and describe the extra allowance under certain conditions. I agree with Wuzhee that using runout with the cone as Datum A would not be the way to go. As long as the runout tolerance is removed, I think setting the cone as Datum...
Wuzhee,
Wouldn't the runout allow the whole cone feature to be offset in reference to Datum A providing the form of the diameter varied less than 0.01? I guess I view it as sort of a bonus. The closer to a perfect circle the diameter is, it would be allowed to be offset slightly. Not saying it...
Thank you all for the replies. In response to a couple:
drawoh, I understand your point about the sharp corner. However, for this part the design doesn't allow for a flat section. The entire taper must be in contact with the mating tapered bore. Even if the corner isn't perfectly sharp...
I would agree. In regard to my original picture, would the current gd&t callout even work? In an effort to support the suggestion of the cone datum with positional tolerance to my department, I would like to understand why it would or wouldn't work. I personally don't believe it is the best way...
Thank you 3DDave for the input. I had thought about using the cone as a datum like you mention but was not sure if that was common practice or if it caused any problems with inspection. I also forgot to mention and show on my picture that we do specify a total runout tolerance of 0.01 on each...
Greetings Everyone,
New to the forums and hoping some of you can shed some light on calling out a profile tolerance on a tapered insert. I have attached a picture of a simplified insert that I commonly work with at my company. From what I have been told, the large diameter dimension, length and...
