Uninzi lwabathengi lubuza malunga nokunyamezela ukutyibilika xa beodolaipleyiti yomphezulu wegraniteBambalwa ababuza ukuba loo mondelo uza kuhlala ixesha elingakanani. Ngumbuzo ofanelekileyo ukuwutsiba xa uthelekisa iikowuteshini, kodwa ngulowo uphela ubalulekile kwiminyaka emithathu okanye emihlanu yobomi bomsebenzi wepleyiti - kwaye kulapho umsantsa phakathi kwamanqaku ubonakala khona.
Iipleyiti zomphezulu wegranite zihlala zihlelwa phantsi kwemigangatho efana ne-DIN 876, ASME B89.3.7, okanye i-GB/T 22095, kunye neegreyidi eziqala kwi-AA ukuya kwi-A, B, kunye ne-0/00 kuxhomekeke kumgangatho osetyenzisiweyo. Igreyidi 00 iphezulu - ukunyamezela okuqinileyo kweplati okunokuqinisekiswa kuko, ngokubanzi kugcinelwe iipleyiti eziphambili zesalathiso, iilebhu zokulinganisa, kunye nokusetyenziswa apho yonke eminye imilinganiselo kwisakhiwo ilandelwa emva kuloo mphezulu mnye. Inxalenye enomdla asilo nani lokuqala kwisatifikethi. Yiloo nto eyenzekayo kuloo nani ngokuhamba kwexesha.
Kutheni iiPlates ezikumgangatho ophantsi zikhawuleza
Ukusithamba kwepleyiti yomphezulu ayilophawu oluzinzileyo; yifoto ethathwe kuhlolo lokugqibela. Ukususela ngoko, izinto ezintathu ziya kuqinisekisa ukuba igcina kakuhle kangakanani:
Uxinano lwezinto kunye nolwakhiwo lweenkozo. Ilitye elinoxinano oluphantsi, okanye ilitye elinenkozo engaguqukiyo, lidla ngokuguguleka ngokungalinganiyo xa kuthe kwasetyenziswa izixhobo eziphindaphindiweyo kunye nokudibana okuncinci. Amabala aphezulu e-microscopic aguguleka ngokukhawuleza kunomphezulu ojikelezileyo, kwaye i-curve yepleyiti ethe tyaba iqala ukutshintsha - kancinci ekuqaleni, emva koko ngokubonakalayo emva kweminyaka embalwa yokusetyenziswa kwemihla ngemihla. I-granite emnyama ethe tyaba, ekwi-3,000+ kg/m³, iyamelana nolu hlobo lokuguguleka okwahlukileyo ngcono, nto leyo eyinxalenye yesizathu sokuba ibe yinto ekhethwayo yomsebenzi weBanga 00 kunokuba ibe lilitye elikhaphukhaphu okanye elinomgodi.
Umgangatho wokusila kunye nokulepha. Ipleyiti egayiweyo ukuya kwiBakala 00 ayipheleli nje ekunyamezeleni ngosuku lokuqala - idla ngokugqitywa ngolandelelwano olude nolulawulwayo lokulepha olushiya isakhiwo somphezulu esifanayo ngaphantsi kokunyamezela okulinganisiweyo. Ipleyiti yomgangatho ophantsi inokufunda kufutshane nenani elifanayo kanye emgceni, ifezekiswa ngokucutshungulwa ngokukhawuleza, kodwa ingaguquguquki kangako ekugqityweni komgangatho ongaphantsi komhlaba. Loo mahluko awubonakali kwiphepha le-spec; ubonakala kwindlela ipleyiti eguga ngayo.
Ukuphathwa nokugcinwa emva kwesiqinisekiso, esisigubungele kwenye indawo, kodwa kufanelekile ukuphinda sikwenze apha - nokuba ipleyiti yeBanga 00 ilahlekelwa yingenelo yayo ukuba igcinwe kwindawo engalinganiyo okanye ishiywe kwigumbi elinolawulo oluphantsi lobushushu.
Oku kuthetha ukuthini kwiMijikelo yoLungiso
Enyanisweni, umahluko webanga uguqulela ekubeni kukuphinda kulinganiswe rhoqo. Ivenkile esebenzisa ipleyiti yeBanga B kumgca wokuhlanganisa oxakekileyo inokufuna ukuphinda ihlolwe kwaye mhlawumbi iphinde iphindwe rhoqo ngonyaka, ngamanye amaxesha rhoqo kuxhomekeke ekusetyenzisweni. Ipleyiti yesalathiso yeBanga 00, egcinwe kakuhle kwindawo elawulwayo, inokuhlala iminyaka emibini ukuya kwemithathu phakathi kokuphinda kulinganiswe ngokupheleleyo - nangona oku kuyahluka ngokwesicelo kwaye akufuneki kuthathwe njengomthetho omiselweyo. Kwilabhoratri yokulinganisa okanye isebe le-metrology elisebenza njengendawo yokujonga yesakhiwo sonke, elo xesha lide alikonga nje iindleko. Linciphisa inani lamaxesha ekufuneka imveliso ime ngawo, okanye kufuneka kungeniswe isalathiso sesibini, ngelixa ipleyiti yokuqala ivaliwe ukuqinisekiswa kwakhona.
Siye sagaya iipleyiti zeBanga 00 kubathengi abazisebenzisa njengereferensi ephambili apho lonke igumbi labo le-CMM liqinisekisiwe khona - amasebe e-metrology eyunivesithi, amaziko kazwelonke, kunye neendawo ezimbalwa zokuvelisa zeFortune 500 phakathi kwazo. Okumangalisa abathengi bokuqala asikokubala ngokwalo, kuba uninzi lwabathengisi abathembekileyo banokufikelela kumanani afanayo ephepheni. Sisicelo, emva konyaka okanye emibini, sokuba idatha yokulinganisa yokuqala ithelekiswe nokuhlolwa kwakhona - kwaye kufunyanwe ukuphambuka kusengaphakathi kwesiqingatha sesatifikethi sokuqala. Olu hlobo lokuqinisekisa oluphindaphindwayo, olwenziwe ngokunyaniseka ngezixhobo ezilandelekayo, yeyona ndlela yokugweba ukuba ibango leBanga 00 lifunyenwe okanye lilinganiswe kanye phantsi kweemeko ezifanelekileyo.
Inqaku Elisebenzayo Kubathengi
Ibanga 00 alifuneki kuyo yonke into esetyenziswayo — kuhlolo oluqhelekileyo okanye umsebenzi wokuhlanganisa, ipleyiti yeBanga A okanye B idla ngokuba lolona khetho lufanelekileyo nolunoqoqosho. Kodwa kwiireferensi eziphambili, ukulinganiswa kwegeyiji, okanye nayiphi na indima apho ipleyiti ngokwayo iba yinto eqhelekileyo ezinye izixhobo ezijongwayo, ukuzinza kwexesha elide kwepleyiti yeBanga 00 eyenziwe ngokufanelekileyo kudla ngokuthethelela iindleko eziphezulu zangaphambili. Uvavanyo lokwenyani asilo isatifikethi esithunyelwa nepleyiti. Yiloo nto isathethwayo seso satifikethi kwiminyaka emithathu, phantsi kwayo nayiphi na imeko ipleyiti ebehlala kuyo.
