[Ji...] Posted July 23, 2021 Share Posted July 23, 2021 Dear Team, Now we have a question about the symbol"SIM". How do we build the alignment? could you help me? Thanks in advance.

[Ma...] Posted July 23, 2021 Share Posted July 23, 2021 Hi, there is info about it. SIM is for Simultaneous requirement - aka pattern. Somewhere in piece are those elements ( plane, cylinder ) interupted. Like pattern for CZ. But i think there should be SIM1 for symetry and SIM2 for position. https://www.mmscience.eu/journal/issues ... s/download Link to comment https://qualityforum.zeiss.com/topic/12434-iso54582018-symbol-quotsimquot/#findComment-62230 Share on other sites More sharing options...

[Da...] Posted July 23, 2021 Share Posted July 23, 2021 The same number shows that the same simultaneous requirement must be applied. Link to comment https://qualityforum.zeiss.com/topic/12434-iso54582018-symbol-quotsimquot/#findComment-62234 Share on other sites More sharing options...
[Ji...] Posted July 23, 2021 Author Share Posted July 23, 2021 how do we build alignment, if it is marked on some different line form? Link to comment https://qualityforum.zeiss.com/topic/12434-iso54582018-symbol-quotsimquot/#findComment-62236 Share on other sites More sharing options...
[Da...] Posted July 23, 2021 Share Posted July 23, 2021 I would measure the side planes of the slots, make center planes, construct centroids of the planes, and use those and the bores in a bore-pattern best-fit.

No, there are no constraints except for datum A, and since there are no constraints except for datum A, you can choose an arbitrary solution. The call-outs are in conformance if you find at least one solution where they’re in tolerance. One way to find such an arbitrary solution is the best-fit as I described it. The envelope condition (E) has no influence on the position or the symmetry (ISO -> Independency principle). Hey, you’re right, this is comedy.
