I-ISO ichaza ukunyamezelwa kwejiyometri njengokuthi "Iinkcukacha zemveliso yeJiyometri (GPS)−Ukunyamezelwa kwejiyometri−Ukunyamezelwa kwefom, ukuqhelaniswa, indawo kunye nokuphelelwa".Ngamanye amazwi, "iimpawu zejiyometri" zibhekisa kwimilo, ubungakanani, ubudlelwane bendawo, njl njl. bento, kwaye "ukunyamezelana" kukunyamezela impazamo.Uphawu lwe "ukunyamezela kwejometri" kukuba ayichazi kuphela ubungakanani, kodwa kunye nokunyamezela ukuma kunye nesikhundla.
Umahluko phakathi kokunyamezelwa kobukhulu kunye nejometri:
Iindlela zokubhala imizobo yoyilo zingahlulwa ngokubanzi zibe ziindidi ezimbini: "ukunyamezela kwe-dimensional" kunye "nokunyamezela kwejometri".Ukunyamezela kwe-Dimensional kulawula ubude becandelo ngalinye.
Ukunyamezelwa kwejiyometri yokulawula imilo, ukuhambelana, ukuthambekela, indawo, ukuphuma, njalo njalo.
Umzobo woNyamezelo oluDimensional
Umzobo wokunyamezela kwejometri
Kuthetha "ukuqinisekisa ukuba umphezulu A awugqithi kwi-parallelism ye-0.02".
Kutheni kufuneka uphawule ukunyamezela kwejometri?
Umzekelo, xa u-odola indawo yepleyiti, umyili wachaza unyamezelo lwedimensional njengalapha ngezantsi.
A Ibhendi yokunyamezelana
Nangona kunjalo, ngokwemizobo engentla, umenzi unokubonelela ngezi nxalenye.
A Ibhendi yokunyamezelana
Amalungu asenokungafanelekanga okanye abe nesiphene ukuba ukuhambelana akuphawulwanga kumzobo.
Umenzi akanalo uxanduva, kodwa kunoko ukunyamezela komyili wokumakisha.Imizobo yecandelo elifanayo eliphawulwe ngokunyamezela kwejometri kunokubangela ukuyila okuboniswe ngezantsi.Ulwazi lwejometri yokunyamezela, njenge "parallelism" kunye ne "planarity", yongezwa kumfanekiso osekelwe kulwazi lobungakanani.Oku kunceda ukuphepha iingxaki ezibangelwa kukuphawula nje ukunyamezelwa kwe-dimensional.
aUkunyamezelwa kweParallelismbUkunyamezelwa kweFlatnesscDatum
Ukushwankathela, ukusebenzisa ukunyamezela kwejometri kunokuphumelela kwaye ngokukhawuleza ukuvakalisa oko umyili afunayo, okungenakwenzeka ngokunyamezela komlinganiselo.
Inkcazo kwi-ISO
Umdibaniso phakathi kobukhulu kunye nokumila kuchazwa ngolu hlobo:
Iinkcukacha kwi-ISO8015-1985eziboniswe kwiplani, njengobungakanani kunye nezithintelo zemilo, azihambelani nobunye ubungakanani, imida, iimpawu zeempawu kwaye zisebenza ngokwazo ngaphandle kokuba kucaciswe ngenye indlela.
Njengoko kukhankanyiwe ngaphambili, umgaqo wokuzimela ngumgangatho wehlabathi ochazwe yi-ISO.Nangona kunjalo, ezinye iinkampani zase-US azinakulandela umgaqo wokuzimela ngokuhambelana ne-ASME (i-American Society of Mechanical Engineers) izikhokelo.Ukuze ugweme nakuphi na ukudideka ngexesha lokurhweba kunye neenkampani zangaphandle, kuyacetyiswa ukuba kuxoxwe kwaye kucaciswe iimfuno ezicacileyo kwangaphambili.
UXiamen Ruicheng ubonelela ngokubonisana simahla kulo lonke uyilo.Zive ukhululekile ukuqhagamshelana nathi ngayo nayiphi na imigangatho yokuvelisa/ukuhlola iimfuno.
