[Cl...] Posted March 29, 2019 Share Posted March 29, 2019 Surface profile, Unilateral Nominal Contour Outside. We just noticed that each part (5 in a row) are all measuring exactly .002. The two basics modified by this profile are; .2535 (length) & .2535 (width). Actuals are consistently roughly .25299 & .25223, and I am seeing a graphical match in the CAD evaluation. We can also correlate these measurements with Mic's, but the profile is always .002??? I tried re-doing the profile characteristic over, but got the same result. Yesterday the results varied??

[An...] Posted April 1, 2019 Share Posted April 1, 2019 Just play around with the tolerance and regard the result of profile. Attached is an assumed scenario.Contribution_01_04_2019_.pdf Link to comment Share on other sites More sharing options...
[Aa...] Posted April 1, 2019 Share Posted April 1, 2019 Profile result always comes directly from the "worst point", so with CAD Evaluation turned on like in your picture, I would search each part for the point that is furthest from the center of tolerance. I think you'll likely find it's a point that has little or no contribution to the widths you calculated. A value of .002" could actually come from a point that is negative, such as a radial corner that is too material-light. Based on your picture, that's what I would look at first.

[Cl...] Posted April 1, 2019 Author Share Posted April 1, 2019 I deleted the CAD model, and brought in a fresh one. That solved the problem. Link to comment Share on other sites More sharing options...
