ASME question; Rule #1

[[Ed...]]

Hi everyone,

I`m working mostly with ISO and just now I started to study ASME.

Like I understood, our customer is not happy with my measuring procedure, so I was wondering how can I proof that our parts are good and according to ASME.

The main question is how do you check rule #1 with Calypso and what you reporting in your measuring report?

I have OD cylinder Ø25.015 (0/-0.013) 

As you see from attached file,

firstly, I measured Cylinder (min circumscribed element) GN

2-Point size (min circumscribed element) GN

Cylindricity (min circumscribed element) GN

Straightness (min circumscribed element) GN

etc...

Is this acceptable for ASME? Is it OK to use "GN" for all dimensions?

If we imagine that my cylinder is at MMC (Ø25.015) does it mean that I need to reject this part, because it will have some form error, but at the MMC it should be perfect? If so, how can I control that? If it will be close to the MMC, how big deviation in roundness, straightness, cylindricity part can be, how to control that?

 

Thanks a lot for any support 🙂
