Kwicandelo elibaluleke ngakumbi lokwenziwa kwezinto ngendlela echanekileyo, isidingo sezixhobo zereferensi ezizinzileyo, ezinokuthenjwa, nezichanekileyo ngokusisiseko asikaze sibe sikhulu kangaka. Nangona iinkqubo ze-metrology zedijithali zibamba iintloko, impumelelo yokugqibela yayo nayiphi na indibano echanekileyo—ukusuka kwizixhobo ze-semiconductor ukuya kumatshini we-CNC ophucukileyo—isaxhomekeke ekuthembekeni kwamanqaku ayo ereferensi ebonakalayo. Phakathi kwezi, i-granite square ruler ivelele njengesixhobo esisisiseko, kodwa kuphela xa ifikelela kwisiqinisekiso esiphezulu: DIN 00.
Ukufikelela kwinqanaba le-DIN 00 akuyonto nje eqhelekileyo; kuthetha inqanaba lokugqibelela kwejiyometri eliguqulela ngqo ekuchanekeni okusebenzayo, okuqinisekisiweyo kumgangatho wemveliso. Eli nqanaba lokuchaneka lilitye lesiseko lokulungelelaniswa kwezixhobo zanamhlanje kunye nolawulo lomgangatho, lisebenza njenge "master square" ebalulekileyo yokuqinisekisa ijiyometri yomatshini, ukujonga ukulingana kwee-axes ze-CMM, kunye nokuqinisekisa ukulingana kweenkqubo zokuhamba ezithe ngqo.
Ukubaluleka kwe-DIN 00: Ukuchaza ukugqibelela kweJiyometri
Umgangatho weDeutsche Industrie Norm (DIN) 875 uchaza ngononophelo ukuphambuka okuvumelekileyo kokuthe tyaba, ukuthe tye, kunye nobukhulu bezixhobo zokulinganisa ngokuchanekileyo. I-DIN 00 imele eyona nto iphambili kolu hlu, "umgangatho wokulinganisa," ogcinelwe izixhobo ezisetyenziswa kwiilabhoratri zokulinganisa ezibuthathaka kakhulu kwaye njengeengcali zokujonga ezinye izixhobo.
Kwinto enkuluirula yesikwere segraniteukuze ithwale uphawu lwe-DIN 00, ubuso bayo obuphambili kufuneka bubonakalise ukuthe nkqo nokuthe tye okuphantse kube ngokugqibeleleyo, kunye nokunyamezela okuqinileyo kokuphambuka kulo lonke ubude bayo. Eli nqanaba lokuchaneka libalulekile kuba nayiphi na impazamo ye-angular kwirula iyanda xa isetyenziselwa ukulungelelanisa ii-axes ezinkulu zomatshini okanye iiplani zesalathiso. Ukuba irula ayisosikwere ngokugqibeleleyo, isixhobo somatshini esilungelelaniswe nayo siya kuba naloo mpazamo ngokwemvelo, nto leyo ekhokelela ekungachanekini kobukhulu kwinxalenye yokugqibela eyenziweyo.
Umyalelo Wezinto Eziphathekayo: Kutheni I-Granite Iphumelela Xa Isinyithi Singasebenzi
Ukukhethwa kwezinto zokwakha linyathelo lokuqala elibalulekileyo ekufezekiseni ukuchaneka kwe-DIN 00. Nangona izikwere zentsimbi zixhaphakile, azifanelekanga ngokupheleleyo kwimeko-bume enamandla nechanekileyo yokwenziwa kwezinto zanamhlanje ngenxa yokuba zinobunzima bokwanda kobushushu kunye nokugqwala.
Igranite ekumgangatho ophezulu, ingakumbi i-gabbro emnyama exineneyo njengezinto ze-ZHHIMG® (ubuninzi ≈3100 kg/m³), inika iingenelo ezintathu ezibalulekileyo ezenza i-granite square ruler ibe ngcono ukuze ihlale izinzile:
-
Ukwanda Okuphantsi Kobushushu: I-Granite ibonisa i-coefficient yokwanda kobushushu ephantsi kakhulu—iphantsi kakhulu kunentsimbi. Kwimeko elawulwa bubushushu, oku kuqinisekisa ukuba i-geometry yomlawuli ayitshintshi kwaphela, igcina isiqinisekiso sayo se-DIN 00 ngaphandle komngcipheko wempazamo ebangelwa kukwanda.
-
Ukuqina Okugqwesileyo kunye nokuDambisa: Imodulus ephezulu yokuthamba okufumaneka kwigranite emnyama yeprimiyamu inika ukuqina okungaqhelekanga. Oku kuqina kunciphisa ukuphambuka xa irula ilawulwa okanye ibekwe phantsi komthwalo. Ngaphezu koko, ulwakhiwo lwayo lwendalo luthintela ngokufanelekileyo ukungcangcazela, uphawu olubalulekileyo xa irula isetyenziswa kunye nezixhobo zokulinganisa ezinobuthathaka kumgangatho wevenkile.
-
Ayinamagnethi kwaye ayimelani nokugqwala: I-Granite ayigqwali okanye ayifuni ukufakelwa uboya obukhuselayo, iqinisekisa ukuba ubuso bayo obusebenzayo buhlala bucocekile kwaye buzinzile ngokwejometri kwiminyaka emininzi yokusetyenziswa. Oku kuphelisa ukungaqiniseki okubangelwa kukuphazamiseka okunokwenzeka kwemagnethi ekuhlolweni kokulungelelaniswa kwezinto ze-electromagnetic.
Umbhobho woBunjineli obuchanekileyo: Ukusuka kwiLitye ukuya kwiStandard
Ukufikelela kwinqanaba le-DIN 00 kwi-airula yesikwere segraniteyinkqubo yokuvelisa eyinkimbinkimbi, enamanqanaba amaninzi edibanisa itekhnoloji ephucukileyo kunye nobuchule bobugcisa obungenakutshintshwa. Iqala ngokukhetha iibhloko zegranite zangaphakathi ezingenaxinzelelo kwaye iqhubeke ngokusila okurhabaxa, ukuguga koxinzelelo, kunye nenkqubo yokuleqa amanqanaba amaninzi.
Amanqanaba okugqibela, abalulekileyo okulungiswa kwejometri adla ngokwenziwa kwiilabhoratri ezilawulwa kakhulu yimozulu, apho ubushushu kunye nokufuma kulawulwa ngokuqinileyo ukuze kususwe izinto eziguquguqukayo kwindalo. Apha, iingcali zemetrology zisebenzisa izixhobo zokulinganisa ezintsonkothileyo—kuquka ii-autocollimators, ii-laser trackers, kunye namanqanaba e-elektroniki—ukuqinisekisa ukuthe nkqo kunye nokuthe tye kobuso bomlawuli. Uhlengahlengiso lokugqibela lwenziwa ngokutsalwa ngesandla okucokisekileyo. Aba basebenzi bezandla, ngamanye amaxesha ababizwa ngokuba “ngamanqanaba e-elektroniki ahambayo,” banamava okuchukumisa ukususa izinto kwinqanaba le-sub-micron, okwenza i-ruler ihambelane nokunyamezela okuncinci okufunekayo yi-DIN 00.
Igunya lemveliso yokugqibela liqinisekiswa kuphela ngokulinganisa okucokisekileyo nokulandelekayo. Yonke irula yesikwere segranite ekumgangatho ophezulu kufuneka iqinisekiswe kusetyenziswa izixhobo ezilandelekayo ezibuyela kumaziko emetrology kazwelonke. Oku kuqinisekisa ukuba isixhobo asichanekanga nje kuphela kodwa sichanekile ngokuqinisekileyo kumgangatho wehlabathi, ovunyelwene ngawo.
Ngaphaya kweLab: Usetyenziso lweDIN 00 Granite Square

-
Ulungelelwaniso lweOptical: Ukubonelela ngendawo yesalathiso esikwere ngokwenene yokulungelelanisa iibhodi zesonka ezintsonkothileyo kunye neenkqubo zelaser apho uzinzo lwe-angular lubalulekile ekugqibeleleni kwendlela yemitha.
Ukuqina nokuqina kwerula yesikwere segranite ene-DIN 00 kuyenza ibe yimpahla esisiseko, yexesha elide kuyo nayiphi na ilabhoratri yokuvelisa okanye ye-metrology ephucukileyo. Imele utyalo-mali kungekuphela nje kwisixhobo, kodwa kwisiseko esiqinisekisiweyo nesipheleleyo sokuchaneka kobukhulu apho zonke izilinganiso ezilandelayo kunye nokulungelelaniswa kuxhomekeke khona. Kubavelisi abalwela ukuchaneka ngeyona ndlela, nantoni na engaphantsi kwe-DIN 00 izisa nje umngcipheko ongamkelekanga.
