E like me nā koi o ke ʻano machining a me ka pololei o ka hui ʻana, e koho ʻia ke kumukūʻai kūpono no ka hoʻomanawanui ʻana.E kuhikuhi ʻia ke ana me ka ʻole o ka ʻae ʻana i ke kaha kiʻi e like me nā koi o GB / t1804-2000 "linear a me ka angular dimensional tolerances me ka ʻole o ka hōʻailona hoʻomanawanui".

Hōʻike kiʻi maʻamau me ka hōʻike ʻole ʻana

E kaha i ka helu maʻamau a me ka helu hoʻomanawanui ma kahi kokoke i ke poʻo poʻo o ke kaha kiʻi a i ʻole nā ​​koi ʻenehana a me nā palapala ʻenehana (e like me nā kūlana ʻoihana).No ka laʻana, i ke koho ʻana i ka pae waena, penei ka lepili:

GB/T 1804-m

ʻO nā kūkulu ʻaʻole i kaha ʻia me ka geometric tolerance i nā kaha kiʻi e kaha ʻia e like me ka papa ma GB / t1184-1996 "geometrical a me positional tolerances me ka ʻole o nā waiwai hoʻomanawanui".[1]
