[Mi...] Posted March 20, 2019 Share Posted March 20, 2019 Per the dwg, I am needing to profile out the Slot. Never had to measure a pro of a slot. I have cad but no curve etcc. with Calypso. I've tried a few different ways but i'm coming up in left field. Again, I do not do many profiles. They are fairly new to me. Just the world I live in LOL Any help in laymans terms... 🤣 🤣 Link to comment Share on other sites More sharing options...
[Da...] Posted March 20, 2019 Share Posted March 20, 2019 Not an expert either, but you could extract the 2 cylinders at each side plus 2 planes (top and bottom) and report the profile for each of those. What's the approx. thickness? Link to comment Share on other sites More sharing options...
[Cl...] Posted March 20, 2019 Share Posted March 20, 2019 Assuming there's a CAD model, I would slice through the slot with at least two nominal planes, (depending how thick the material is?) Then create a pair of 2d curves, and recall them into a FFS. Link to comment Share on other sites More sharing options...
[Mi...] Posted March 20, 2019 Author Share Posted March 20, 2019 The bracket is 1.5mm thick so not much there. Link to comment Share on other sites More sharing options...
[De...] Posted March 20, 2019 Share Posted March 20, 2019 Do what Dane said above, two planes two cylinders, 4 separate profile charachtaristics with the same datum reference frame. Create maximum result characteristic and use the four profile characteristics inside it to report max profile for entire slot. If necessary mask the 4 independent profiles from your report to keep things neat. Done. Link to comment Share on other sites More sharing options...
[Da...] Posted March 20, 2019 Share Posted March 20, 2019 Regarding to 1.5mm thick, you might want to take 2 circles and 2 lines. Just an idea. Link to comment Share on other sites More sharing options...
[Mi...] Posted March 21, 2019 Author Share Posted March 21, 2019 Great Ill get to work on some of this and see what I can come up with for sure Thanks Link to comment Share on other sites More sharing options...

[Al...] Posted March 22, 2019 Share Posted March 22, 2019 I measure a lot of slots with tight profile tolerances. Curve makes it easy but try this: 1) Create a secondary alignment using -A-B-C-; have all Datum features set to Outer Tangential; constrain the features and you have created a true datum reference frame just as you would on the characteristic side. 2) Measure the slot using Space Points, using the constrained secondary alignment, and report Space point Distance with a +/-.0035. Go heavy with the points in the radial areas, I always find that to be a problem area. When the machine is interpolating those features there is usually a jump when the screws start to change direction to complete the arc. Give it a try.
