[To...] Posted April 24, 2019 Share Posted April 24, 2019 Hi guys. Long time no see. Now, I'm working on a project involving a shape that is probably best called out as Surface Profile but this customer has not adopted this mentality yet. They have a shape that they specify to be within .XXX of BASIC, so Surface Profile with no DRF seems to fit the bill. Then, they are asking for the Position, with MMC, of this shape to a DRF. If this shape was a cylinder, or cone, I'd already know what to do. However, I'm a little perplexed on how to incorporate MMC from the shape. The attached sketch is not the actual part but represent the basic part shape. Any ideas? . . Link to comment Share on other sites More sharing options...
[Ma...] Posted April 24, 2019 Share Posted April 24, 2019 Ho Ho Ho, Hi Tom, sorry verstehe die Darstellung leider nicht so richtig. Hast Du einen besseren Zeitungsausschnitt 😱 ? Ist es möglich Freiformfläche zumessen und eine Einpassung zumachen? Die Werte der Translation in ein Resultate Element zu übernehmen? MMC mit einer Formel Berechen? 🙄 Christian Link to comment Share on other sites More sharing options...
[Br...] Posted April 24, 2019 Share Posted April 24, 2019 So are you saying there there is a profile to no DRF then a Position at MMC on the shape? Something like this? If that's the case you have an irregular feature of size. If the irregular feature of size is an internal feature, then it has an inner boundary established by the collective effects of the profile and the position, and an outer boundary governed by the profile alone. If Its an external feature, its the reverse of that. You will need to create two profile characteristics with calypso to do this. The first one will be straight forward to control the Profile with no DRF. The second one will be to create the inner Virtual condition boundary. Set the profile tolerance zone to "Inward to Infinity". To figure out the Profile tolerance, add half of the profile tolerance to half of the position tolerance, or simply add the two tolerances together and divide the sum by 2. If you have access to Y14.5-2009, the priniples from what I've explained can be found in Fig. 8-24. Link to comment Share on other sites More sharing options...
[To...] Posted April 24, 2019 Author Share Posted April 24, 2019 Hey Brett. Thanks for the reply. I didn’t consider looking in my Y14.5 book to see if there was an example already. That wouldn’t have told me how to do it. I haven’t fully digested your reply but wanted to say thanks. I’ll let you know how I made out. Link to comment Share on other sites More sharing options...
