[Vi...] Posted May 6, 2021 Share Posted May 6, 2021 Buongiorno avrei bisogno di sapere come si calcola questo valore diametrale.. per caso fa riferimento al minimo inscritto di un valore diametrale?

[Vi...] Posted May 6, 2021 Author Share Posted May 6, 2021 Grazie mille per la risposta ma potresti essere più chiaro al riguardo... Link to comment https://qualityforum.zeiss.com/topic/12874-calcolo-inviluppo-diametro/#findComment-65040 Share on other sites More sharing options...
[Ün...] Posted May 6, 2021 Share Posted May 6, 2021 If the hole diameter is the min size of the diameter, if it is the outer diameter, you should report the maximum size.

[Vi...] Posted May 6, 2021 Author Share Posted May 6, 2021 Quindi mi dai conferma che si tratta di avere il valore diametrale minimo inscritto...

[Se...] Posted May 6, 2021 Share Posted May 6, 2021 ciao Vincenzo, Il principio di inviluppo, indicato con la lettera E riassume in un solo simbolo due specifici operatori. Infatti, per le feature esterne (fig. 12) il modificatore di inviluppo ha lo stesso significato di un operatore GN (minimo inviluppo circoscritto) per il limite superiore e di distanza tra due punti per il limite inferiore. Per le feature interne (fig. 13), il modificatore di inviluppo ha lo stesso significato di un operatore GX (massimo inviluppo inscritto) per il limite inferiore e di distanza tra due punti per il limite superiore.Envelope.png Link to comment https://qualityforum.zeiss.com/topic/12874-calcolo-inviluppo-diametro/#findComment-65046 Share on other sites More sharing options...
[Da...] Posted May 24, 2021 Share Posted May 24, 2021 Ciao Vincenzo, scusami se mi accodo. Ho il tuo stesso problema e non sono ancora riuscito a risolverlo pienamente. Posso chiederti che versione di Calypso stai usando?

[Da...] Posted May 24, 2021 Share Posted May 24, 2021 I have never seen a dimension where both the upper and lower tolerances were negative numbers, how does that work? The callout is Ø47 -0,008 and -0,033. Is it allowed to go up to 47 or only 46,992? Is it a typo and the upper is supposed to be + not -? I understand the envelope is for fit in the assembly.

[To...] Posted May 24, 2021 Share Posted May 24, 2021 Please sign in to view this quote. 46.992 is the limit. It is a way to designate a "nominal" size of hardware.

[Da...] Posted May 24, 2021 Share Posted May 24, 2021 Please sign in to view this quote. Both inner diameter callouts are correct. Tolerances come from https://www.iso.org/standard/63969.html.
