[pa...] Posted August 23, 2021 Share Posted August 23, 2021 Hello all. I recently returning to Calypso programming after approx 10 yrs. I am having difficulties with a true position. I will post a sketch of the issue (as I can not share the print), any suggestions would be appreciated. I did not put on drawing, if I intersect the cylinder with the plane I get a true position of .006, however I cannot apply bonus tolerance. so I know the position is not as far off as Calypso is telling me for the cylinderimg08232021_0002.pdf Link to comment Share on other sites More sharing options...
[Ri...] Posted August 23, 2021 Share Posted August 23, 2021 These are not fun. You will have the rotate the alignment. The first will be the 32° angle from -C- to the hole. The second will be the 37.5° from -A- to the hole. The main reason why you are seeing huge errors if you just plug it in is because the Position creates a zone of tolerance that is either perpendicular or parallel to the primary datum. Obviously this hole isn't perpendicular or parallel to A, so you have to take that nominal rotation out of it. Calypso will not allow you to use the MMB on the Datum holes once you start rotating the alignment around. Link to comment Share on other sites More sharing options...

[Me...] Posted August 30, 2021 Share Posted August 30, 2021 Please sign in to view this quote. I would add that this is one way to measure an angled hole's True Position but not the only. The issue with that method isn't going to be one that I would suggest to Basic Level Programmers that have to deal with Manufacturing Engineers & Machinists that make adjustments on the fly. Rotating in the Special tab to the nominal angle or having an alternate alignment rotated is my preferred methods due to experience with the rest of the shop/business and ease of adjustments.

[Ma...] Posted August 31, 2021 Share Posted August 31, 2021 Please sign in to view this quote. P1 and P2 are center of tilted cylinder. P1 is from upper plane and P2 is from bottom plane. It's not only 60° rotated, it's 32,27014° titled on that 60° plane Link to comment Share on other sites More sharing options...
