First of all I would like to thank everyone for some good conversation on this subject.
Dean hit on the subject that we are looking at, and that is the point cloud, white / blue light scanning. We are currently working with a place that scans the parts and gives us a cad model of it. We...
pmarc,
If that is the case then how do we trust them to check the parts that they are responsible for correctly? Do you have your suppliers go through an inspection house that your company has certified? We can design and engineer a part to death but if we don't know what we are actually...
The way the system is running right now seems to be a conflict of interest. The supplier is checking their own part through their own inspection or one that is hire by them. Every inspection report seems to have obvious errors, errors that are calculated by their own results on the report...
[banghead] I need to vent a little here.
As a company we put a lot of time and effort in the design, engineering, analysis of our products. We check to make sure the drawings are within the standards of the ASME Y14.5M. We do extensive interactive hi/lo’s on the assembly and all the...
pmarc,
By definition, I would say it sure would. Circularity is each line element sperately, unlike if there were a straighness (on the FOS) or cylindricity callout on that cylinder.
Chris,
I took your part and showed what would pass on a functional gage, and then took that part and set it up at RFS to Datum B and Datum C. You can see that a part that would fit on the gage would seem way out on a system that does not applied the datum shift.
Chris,
If you can attach a picture may clear a lot of thngs up for me. There can be no MMC condition on Datum A since it is a plane. Is there a perpendicularity tolerance on Datum B ar MMC to Datum A? Is Datum C relative to Datum A&B or just B and at what material condition? When using the...
