Profilr surface tolerance for not oriented slot
Profilr surface tolerance for not oriented slot
(OP)
Dear Guys,
Hello to everbody who read my post.
I need to understand if the use of profile tolerance fully define the shape and orientation of this slot as per attached picture.
If not you think that I need to add basic dimensions? I'm in trouble to define basic dimensions to these datums as the slot is not oriented as them.
I hope somebody has some suggestions.
Thank you very much in advance.
Filippo

They, for example, are not subject to tolerance accumulation, so you can use as many as you want, as long as eventually you connect your feature to datum.

Many thanks for your very quick reply!
Now the situation is more clear. So I will proceed to add basic dimension for locate the tollerance zone to the basic datum as stated in the feature control frame.
In case the shape of the slot will become very complex, as instance an irregular profile very difficult to locate with dimensions do you think I need to made reference to cad model?
Do you think it works well for both ASME and ISO standard?
Keep in touch! Thanks!
