No IM sorry..
Tolerance is pretty easy, measuring it or keeping it is hard! DO a google and that will sort out the idea. Your part as drawn is to some very stringent tolerances that the 'real' part doesn't need.
As drawn its got complex blades which will make it expensive to produce does your version need that?
As drawn the root of each blade has a very small radius and xsection which make it difficult to machine and the part weak. 'Real' turbines and compressors usually have a blade profile that gets thicker towards the back disk.
If the application allows it a wheel with straight blades, bigger radius and lower tolerances would be far easier and hence cheaper to produce. Tolerances of 0.02 on a small machine on such a part this complex would be possible with a bit of practice. |
