[Ia...] Posted September 20, 2022 Share Posted September 20, 2022 I have a part with hundreds of holes, and I'd like to just report the worst position. However, I'm unsure of how to apply the correct MMC bonus to the Max characteristic. I have PCM, but have literally no experience with it other than basic formulas.

[Ia...] Posted September 20, 2022 Author Share Posted September 20, 2022 Rereading this, I realize I'm not as clear as I'd like to be. I'd like to grab the size of the worst positioned hole and add the MMC bonus to the max characteristic. A prior programmer just left the tolerance to print with no MMC. But some reports will only have this max characteristic as non conforming, when it is actually in tolerance with MMC. Link to comment Share on other sites More sharing options...
[Cr...] Posted September 20, 2022 Share Posted September 20, 2022 Could you take your total diameter tolerance and just add it to your positional tolerance in the maximum characteristic? Example: A ±.001 diameter would gain you .002 of positional tolerance. You could then add it directly to the upper tolerance in your maximum characteristic. I run into this issue as well. Not sure if that will work for you Link to comment Share on other sites More sharing options...
[Ri...] Posted September 20, 2022 Share Posted September 20, 2022 Please sign in to view this quote. You would have to calculate the difference of size to the tolerance, and to ensure you're not adding any additional modifier tolerance you have to calculate out any oversize or undersize condition. You cant just add the feature tolerance as whole value. Link to comment Share on other sites More sharing options...
