Kwihlabathi elizenzekelayo kakhulu lobunjineli obuchanekileyo kakhulu, apho iinkqubo zokulandelela i-laser ezintsonkothileyo kunye nee-algorithms ezintsonkothileyo zilawula ulawulo lwentshukumo, kunokubonakala ngathi kuyaphikisana nokuba ukuchaneka kwejometri kokugqibela kusaxhomekeke kwizixhobo ezisusela kwimihla yokuqala ye-metrology. Sekunjalo, njengoko eli shishini liqhubeka lingena nzulu kwiindawo ze-sub-micron kunye ne-nanometer, indima esisiseko yezixhobo ze-precision granite—ingakumbi i-granite straight ruler ene-Grade 00 precision, i-granite square, kunye ne-isikwere se-granite tri—ayigcinwanga nje kuphela, kodwa ikhuliswa. Ezi zixhobo ezingashukumiyo, ezingasebenziyo ziindawo zokubhekisa ezingaguqukiyo eziqinisekisa ukusebenza kweenkqubo ezinamandla eziphambili.
Imfuneko yezi zixhobo zereferensi zegranite ivela kumgaqo osisiseko wezinto eziphilayo: uzinzo lobushushu nolwemishini. Nawuphi na umatshini owenzelwe ukuchaneka okuphezulu kufuneka uqinisekise ukuba iindlela zawo zokulinganisa kunye nokuhamba okuthe tye ziyinyani, zithe tye, kwaye zithe nkqo. Xa imveliso yanamhlanje ifuna uzinzo olunemilinganiselo engachaphazeleki kukutshintshatshintsha kobushushu okanye ukungcangcazela kwangaphandle, izinto ezifana nentsimbi okanye isinyithi esityhidiweyo—ezinomlinganiselo ophezulu wokwandiswa kobushushu (CTE) kunye nomthamo ophantsi wokudambisa—ziyasilela kuvavanyo.
Kwelinye icala, igranite ibonelela ngendawo efanelekileyo yozinzo. I-CTE yayo ephantsi ithetha ukuba utshintsho lobushushu lubangela ukushukuma okuncinci, nto leyo eyenza ukuba ibe yinto efanelekileyo yokuchaza iplani yesalathiso ehlala iqikelelwa. Ngaphezu koko, amandla ayo aphezulu okudambisa afunxa ukungcangcazela ngokukhawuleza, ithintela ingxolo kunye nokuvakala okuza kusasazwa zizixhobo zesinyithi, nto leyo ibalulekileyo kwiilebhu zemetrology nakwiindawo zokuhlanganisa apho ingxolo yendawo isoloko ingumngeni.
Isiseko soLungelelaniso: Umlawuli oQondileyo weGranite oneBanga le-00
Ukulinganiswa kobuthe ngqo yeyona nto ibalulekileyo kwi-dimensional metrology. Zonke izikhokelo ezithe ngqo, i-air bearing, kunye ne-CMM axis zixhomekeke kwindlela ethe tye engqinisisekayo yokuhamba. Kwizicelo ezifuna amandla ngokwenene, i-granite straight ruler ene-Grade 00 precision iba yeyona nto ibalulekileyo.
Ukutyunjwa kweBanga 00 (okanye iBanga elilinganayo leMaster) kubonisa inqanaba eliphezulu lokuchaneka elinokufezekiswa ngaphandle kweelabhoratri zemigangatho yesizwe. Eli nqanaba lokuchaneka lifuna ukuba ukuphambuka kokuthe tye kumda wonke wokusebenza werula kufuneka kulinganiswe ngamaqhezu e-micron. Ukufezekisa eli nqanaba lokuthembeka kwejometri akufuneki nje kuphela izinto ezifanelekileyo kodwa kunye nenkqubo yokuvelisa elawulwa ngononophelo.
Inkqubo yokuvelisa kufuneka ilandele imigaqo engqongqo yamazwe ngamazwe, efana nemigangatho ye-DIN, JIS, ASME, okanye i-GB. Le migangatho yehlabathi ilawula iinkqubo zovavanyo, iimeko zokusingqongileyo, kunye nokunyamezela okwamkelekileyo. Kubavelisi abakhonza abathengi behlabathi—ukusuka kwiifemu ze-semiconductor zaseJapan ukuya kubakhi bezixhobo zoomatshini baseJamani—ukukwazi ukuqinisekisa i-granite straight ruler ngokuchasene nemigangatho emininzi ngaxeshanye luphawu lobuchule bobugcisa kunye nokuqina kwenkqubo esemgangathweni. Umsebenzi walo mbusi ulula: ukubonelela ngomgca ongasebenziyo, ongatshintshiyo apho impazamo yokuthe tye ye-dynamic machine axis inokumatshwa kwaye ihlawulwe.
Ukuchaza uBume obuNgqo: I-Granite Square kunye ne-Granite Tri Square
Ngelixa ukuthe tye kulawula umgangatho wokuhamba okuthe tye, ukuthe nkqo (okanye isikwere) kulawula ijometri yokusebenza komatshini. Indawo yokudibana kwee-axes zokuhamba (ezifana nee-axes ze-X kunye ne-Y, okanye i-axis ye-Z ngokumalunga neplani yesiseko) kufuneka ibe yi-90° ngokuchanekileyo. Nakuphi na ukuphambuka apha, okwaziwa ngokuba yi-squareness error, kuguqulela ngqo kwi-positional error, okwandisa ubunzima bokufikelela kwindawo echanekileyo yokubekwa kweempawu.
Isikwere segranite kunye nesikwere segranite tri zezona zixhobo ziphambili ezisetyenziselwa ukuqinisekisa le engile isisiseko.

Isikwere segranite sidla ngokusetyenziselwa ukuqinisekisa ubume besikwere see-axes zomatshini xa kuthelekiswa nepleyiti yomphezulu wesalathiso okanye ukuqinisekisa ubume obuthe nkqo bezinto ngexesha lokuhlanganiswa. I-geometry yayo eqinileyo enobume be-L iqinisekisa ukuba ubuso obubini obusebenzayo bugcinwa kwi-engile ye-90° eqinisekisiweyo.

Isikwere se-granite tri (okanye isikwere esikhulu) sinika ulwakhiwo olulodwa lwejometri olunobuso obuthathu, oluvumela ukujonga okubanzi ngakumbi kwejometri yetyhubhu ngaphakathi kwisakhelo somatshini. Olu lwakhiwo luluncedo ngokukodwa ekumiseni imida yetyhubhu yeCMMs okanye iifreyimu ezinkulu zomatshini, ukuqinisekisa ukuba zonke iiplane zisikwere esinye kwesinye nakwisiseko.
Njengerula ethe tye, ezi zikwere kufuneka zifumane isiqinisekiso seBanga 00, zifuna ukuba ii-engile zihambelane nazo ngaphakathi kwemizuzwana embalwa. Lo ngumsebenzi oxhomekeke ekuzinzeni okuphezulu kwezinto zegranite kunye nobuchule obungenakutshintshwa bezakhono zobungcali ezisebenzisa amava amashumi eminyaka kwinkqubo yokuleqa ngesandla ukuze zifezekise i-geometry yokugqibela, engenasiphako yomphezulu.
Inkqubo yoBugcisa: Okungaphezulu nje kwelitye
Igunya lezi zixhobo ze-granite metrology alikho nje kwizinto ezisetyenzisiweyo, kodwa likwi-ecosystem yonke exhasa isiqinisekiso kunye nokuveliswa kwazo. Iinkampani eziphambili kweli candelo ziyaqonda ukuba ukuchaneka yinkcubeko, kungekuphela nje kwenkcazo yemveliso.
Iqala ngeengcali zobungcali. Kwiiworkshops ezikhethekileyo nezilawulwa kakhulu, iingcali zokusila ngokuchanekileyo zihlala zinamava eminyaka engamashumi amathathu nangaphezulu. Aba bantu banobuchule ekusebenziseni iipleyiti zokulapha ezikhethekileyo kunye neekhompawundi ezirhabaxa ukulungisa iziphene ezincinci ngesandla, behlala besebenza kwiindlela ezinokuthi zibonwe zizandla zabo ngcono kunezinye iisensa ze-elektroniki. Ulwazi lwabo oluqokelelweyo lubavumela ukuba bafikelele ekugqityweni komphezulu okutyhala imida yokuthe tyaba kunye nokuthe tye, ngamanye amaxesha befikelela kwisikali se-nanometer ukuze kugqitywe kakuhle okufunekayo kwizicelo zokuthwala umoya. Olu buchule bomntu luphawu oluphambili ekufezekiseni iimfuno ezingqongqo zeBanga 00.
Olu buchule buhlolisiswa kwaye buqinisekiswe ngokucokisekileyo. Indawo yokuvelisa kufuneka izinze kakhulu, inamagumbi acocekileyo alawulwa yimozulu, iziseko zekhonkrithi ezichasene nokungcangcazela, kunye nezixhobo zokulinganisa ezikhethekileyo ezifana nee-laser interferometers kunye namanqanaba e-elektroniki ahlala elinganiswa kwaye alandelelwa kwiilabhoratri zemigangatho yesizwe. Oku kuzibophelela kuqinisekisa ukuba i-geometry eqinisekisiweyo yecandelo ihlala iyinyani ukususela oko liphuma kumgangatho wefektri.
Ukuthembela kwezi zixhobo zakudala kodwa ezigqibeleleyo kugxininisa inyaniso enzulu kubunjineli obuchanekileyo kakhulu: ukuphishekela isantya esiguqukayo kunye nobunzima bokubala kufuneka kuhlale kunamathele kwinyani yejiyometri engaguqukiyo nengqinisisekayo. Irula ethe tye yegranite enobunono beGrade 00, isikwere segranite, kunye nesikwere segranite tri azizo iintsalela zexesha elidlulileyo; ziyimigangatho efunekayo, engaguqukiyo eqinisekisa ukuthembeka kwejiyometri yexesha elizayo. Ngokugcina ukunamathela ngokungqongqo kwimigangatho ye-DIN, JIS, ASME, kunye ne-GB, abavelisi abaziingcali baqinisekisa ukuba iqhekeza elisisiseko lelitye lihlala lisesona sixhobo siphucukileyo esifumanekayo sokuchaza inyaniso yobukhulu.
