Re: Difference a gage can detect

Yes it is automated.
Please, more details.
  1. What happens when the system detects a nonconforming part?
  2. How is the system set up to make measurements? Do you (for example) enter the acceptable range?
  3. Why wouldn't the gage be able to distinguish between different parts? Isn't that what it's supposed to do (i.e., detect part B as nonconforming if the system is set up to measure part A?)

1. When the system detects a non-conforming part it marks the part on the pallet as a reject and gets off loaded into a reject bin at the end of the line.

2. We enter an acceptable range and conduct a Gage R&R for this range. So the original range was 1-3mm and now product wants to know how different would the next "widget" need to be so that we can tell the difference. (i.e. would it need to start at 3.1 or 3.2 or 3.5 or 4)

3. We want to make sure that it is able to distinguish between the parts that are newly created. The gage is correct for the first type of part. The biggest difficulty comes when product wants to back tolerances up to each other or overlap.

You need to know something about the measurement uncertainty for the gage if you're reasonably confident that the resolution is adequate. If tolerances overlap, all bets are off, of course.

Kelly, do you think we can guess your product by telling us the tol for it? and what the gage measures? There is experts here, but we really can not help without some information.

hello and greetings!

im currently enrolled in a basic MSA class in our college. sadly, i really need help with following GR&R sheet. Would you be so kind to check it for me, and fill the missing pieces? tnx in advance.
our professor was'nt so clear in explaining things.

P.S. some data (measurements) have been deleted so that the R chart is in check; i just need to know the how-to-do's in the last part. :)
