[Ma...] Posted September 9, 2021 Share Posted September 9, 2021 Hello, I can not find something to handle this line profile callout with angle. Any ideas? Link to comment https://qualityforum.zeiss.com/topic/11416-how-to-eval-line-profile-with-ref-angle/ Share on other sites More sharing options...
[Cl...] Posted September 10, 2021 Share Posted September 10, 2021 What does the part/surface look like? Link to comment https://qualityforum.zeiss.com/topic/11416-how-to-eval-line-profile-with-ref-angle/#findComment-56326 Share on other sites More sharing options...
[Ma...] Posted September 13, 2021 Author Share Posted September 13, 2021 Sorry for delay - i rather use real drawings instead handwritten from memory. This is partly cleared drawing - line profile goes for involute defined by radius which have +/- 0,2mm tolerance and have to sides on part. No other dimensions are drawn for this ( except from start and end of dashed line of profile ) Part is called in DE - Bremsnocken / translated from CZ to EN - brake key Link to comment https://qualityforum.zeiss.com/topic/11416-how-to-eval-line-profile-with-ref-angle/#findComment-56328 Share on other sites More sharing options...
[Cl...] Posted September 13, 2021 Share Posted September 13, 2021 Looks to me like the drawing wants in addition to the 0.2 tolerance a 0.1 tolerance for every 15° segment? I do see in the drop-down menu of the line profile characteristic and option named "Evaluate tolerance segments individually".

[Ma...] Posted September 13, 2021 Author Share Posted September 13, 2021 As we lack in knowledge of involutes I wonder, if are both sides connected somehow. There is no base for eval, so we ended in bestfitting whole sides of involute as pattern. I did not tried to measure from blueprint drawn segments if they fit 15°. I tried curve jump, but i don't understand it right. I have model in nominals - so involute is in middle of tolerance - nothing is set as basic dimension so i really don't know if bestfit of both sides as pattern is right. It would be real pain to divide curve ( we have 4 - 2 sides at two heights ) into segments. Any guide?

[Ma...] Posted September 14, 2021 Author Share Posted September 14, 2021 I was looking for "Evaluate tolerance segments individually" and found it. But it gives me only deviations as max and min without doubling it. We are reporting only one number for this position to customer. Still can not figure out how to correctly finish it 🙁 Edit: For full drawing there is diameter of center circle labeled as "Circle involute with R +/- tol active camshaft radius" and it is marked as base "A", which is used for symmetry of width. So can I evaluate each curve independently?

[Ia...] Posted September 14, 2021 Share Posted September 14, 2021 You can use result element to grab the max of the absolute values of min/max, and multiply it by 2.

[Ma...] Posted September 14, 2021 Author Share Posted September 14, 2021 Please sign in to view this quote. Still it's not resolving my problem. If i would report worst 15° segment and doubling it's value i'll get same value as whole line profile. In circular slice you just put element and angle of segment. Since it have no base for eval, then it would have sence to have smaller tolerance for segment. But i don't know if both side are tied up with involute start radius and it's center.

[Ma...] Posted December 14, 2021 Author Share Posted December 14, 2021 Thanks Guenter, that's at least one good feature of new version. But i don't think i'll get newer version. Customers sometimes demands our programs to clarify our strategy.
