One doubt is there, if we are going from the top of gap by using vector method the mean is coming as -.024. So is there strict rule like we need to start with bottom end of gap something like that??
you did not say anything about the results. Despite the fact that WC shows screws notching together by .022 and RSS is showing clearence .005. Wich results shoud i take for granted? thank you
You pick your starting point and decide which direction you go to get to the other side of the gap. He mentioned that his assumption is always moving up and to the right are positive values and the opposite direction is negative.
The sigma value has to do with process capability, or how good the manufacturer is at delivering parts within the specified tolerance range. This guide might help: www.fiveflute.com/guide/introduction-to-root-sum-squared-rss-tolerance-analysis
Just found this and gave it a try. I use metric dimensioning and when I put a tolerance in that is over 1 it errors and locks up excel. For example: location of a hole with a true position tolerance of 1.5 Any Ideas?
Chris Leamon I do not believe you are getting the error because of the size of the tolerance, per so. I think you are encountering an error because the gap equation is empty. It still should not be locking up Excel, so we will be taking this up with the developers to add clarity to the error message and stop it from locking up the application. I will re-post when the fix has been implemented. In the meantime, remember to populate the gap equation.
