Hi all...
Hope i'm posting this in the right section...
I'm a self-employed engineering designer, currently designing a "part-specific" receiving gauge for a Ford bracket.
I've done a few designs earlier which work absolutely fine and with the gauge currently in question, i have a problem. I am pretty much new to the process, but i have quite an idea of how things work.
The job has two ear-like projections with quite a long gap in btwn. One face of the ear-like-projection has to be checked for flatness, also it's M10 thread. The other projection, separated with no material in btwn, has a D20mm bore. No flat-face check here. However, the complexity of the 3D tapering-contour around the D20mm bore, which is such that a gauge portion (even a P-like projection from the gauge) is not possible, (view the snapshots attached, please) calls for the pin to engage with the job/component first and then with the gauge. The check is only for concentricity and bore size.

Is this an accepted procedure considering that by protocol (or so i thought), the pin should enter the gauge portion first and then the component?:confused:
Please let me know...

Thoughts from anyone?

tho am still expecting a response from someone, i've received a go-ahead from my client for the current configuration. thoughts welcome. in fact, i was abt to type "good suggestions get a complimentary dinner for two at a restaurant of your choice". so pl comment. pour in thoughts, just loud-think. u never know what might help.

Hello Prana, welcome to the cove.:bigwave:

I see you are new here, so my advise is to refrain from 'offers' for getting good suggestions. Covers here work on the principle of 'Help each other', and they will only be more than happy to help you, just have to be patient.

Can you rephrase your querry since it is unclear(to me), and also mark the area that is to be checked for flatness & thread, and the bore. Also tell us w.r.t. what, the concentricity of D20 bore is required to be checked?

Umang :D

Flatness with what looks like a plug gage, the only way you could check that flatness would be with a feeler gage. You could just use a striaght edge scale to lay on there for that check. The other is a plain simple plug gage from what I can tell. I would have them put centers on each end for a fast recheck of the gage. Putting a head on one end may lead to a operator beating it in with a hammer, LOL. I have seen lead men do worse to a gage.
