[Ia...] Posted June 19, 2019 Share Posted June 19, 2019 Hello, I am very new to Calypso(only a couple months), and am faced with the challenge of measuring the true position for open ended slots around the circumference on a cylinder. I can't see how to program this in calypso. Could someone please walk me through this? Best Regards. Link to comment Share on other sites More sharing options...
[Me...] Posted June 19, 2019 Share Posted June 19, 2019 Create a plane on each side/wall of the slot. Create a symmetry plane, recall feature points, and recall the 2 planes from the slot. Fix any nominals as needed. True position the symmetry plane. A symmetry plane will allow the use of material condition. Robert Link to comment Share on other sites More sharing options...
[Ia...] Posted June 20, 2019 Author Share Posted June 20, 2019 Thank you for the reply Robert. I tried creating the symmetry plane and asking for a true position of the symmetery plane. It was showing a deviation of up to 0.600" which is not possible. Could it be that I have patterned all of my planes? I have six slots around the circumference.

[Br...] Posted June 20, 2019 Share Posted June 20, 2019 If the planes are nominaly (Basically) on an angle other than 0 or 90 degrees from the datum reference frame, you have to click the "special" button in the Position characteristic and rotate the DRF to the Basic angle.

[Ia...] Posted June 20, 2019 Author Share Posted June 20, 2019 Ok, thank you Brett, I'll give that a try. Link to comment Share on other sites More sharing options...
[Ia...] Posted June 24, 2019 Author Share Posted June 24, 2019 Ok, I tried roatating the DRF to the Basic basic angle. I got a true position result that is somewhat believable on the first slot. However the remainig 5 slots in the pattern were showing results 0.600"-0.700". I think I may have to programa each slot individually in order to get the results that I am looking for. Which makes the pattern function useless in my case. Link to comment Share on other sites More sharing options...
[Me...] Posted June 24, 2019 Share Posted June 24, 2019 If you want to keep the feature patterned, you'll need to use a formula in the position characteristic that rotates the coordinate system with each index. rad(LOOP1*60-60) Link to comment Share on other sites More sharing options...
[Me...] Posted June 24, 2019 Share Posted June 24, 2019 Don't get me started on the pattern feature! 🤬 🤣 Link to comment Share on other sites More sharing options...
[Da...] Posted October 28, 2021 Share Posted October 28, 2021 Please sign in to view this quote. Hello, how exactly do you use this formula. i'm trying to check a pattern of 600 slots all around the center of an OD. .54° spaced out. Link to comment Share on other sites More sharing options...
[Aa...] Posted January 20, 2022 Share Posted January 20, 2022 Daniel, sorry to revive an old thread. Where do you put this formula, and what do I vary the '60' based on the angle of of my slots? I am trying to create a best-fit bore pattern of 5 radial slots (every 72 degrees). Thanks! Link to comment Share on other sites More sharing options...
[Cl...] Posted January 20, 2022 Share Posted January 20, 2022 Open ended slots? Sounds like they are not a feature of size? Maybe surface profile would be better callout, just sayin. Link to comment Share on other sites More sharing options...

[Aa...] Posted January 20, 2022 Share Posted January 20, 2022 Clarke, They are not open ended slots. It's also driven by the customer, so we are stuck with TP. Link to comment Share on other sites More sharing options...
