Double up with tolerances
Hi all,
I am currently working on some drawings and we are in the process of setting up the tolerances. Now a co-worker has during my vacation done a preliminary suggestion of the geometric tolerance. As I am now looking through this some questions arise, and I hope I could get some input on this.
The question at hand is regarding double tolerances. And if in these cases one is making the other one obsolete.
Case one;

In this case, would not the total runout tolerance be obsolete when the profile of the surface is kept that tight? Or can they be used together and if so, how does that work?
Case two;
[ATTACH=CONFIG]696[/ATTACH]
In this case, will the flatness be needed when you state that perpendicularity? Will not the perpendicularity tolerance demand that the surface as a whole is within that 0.1 limitation? If not how does these to play together?
Thanks for all the help, and thanks for having such a great community. Just discovered these forums and I am most happy to be here.
Kind regards.
