Kwiinjineli ze-QC ezifanelekileyo kwisicwangciso esitsha se-metrology, abaphathi belebhu bachaza isalathisoipleyiti yomphezulu, okanye amaqela okuthenga afumana izixhobo ezisisiseko zeeplatifomu ze-semiconductor kunye ne-CMM, umbuzo omnye uhlala uvela: zeziphi izinto eziza kuhlala zinyamezelekile kwiminyaka emininzi yokusetyenziswa kwemveliso - kungekuphela nje kwingxelo yokuhlolwa, kodwa kumgangatho wefektri?
Intsimbi iyagoba phantsi koxinzelelo olushiyekileyo. Isinyithi esibunjiweyo siyabola kwaye sithwala amandla emagnethi aphazamisana nezinzwa ezibuthathaka. Kwane-aluminium eyenziwe kakuhle ishukuma ngokulinganisela xa kujika ubushushu obuphakathi. Yingakho amashishini achanekileyo kakhulu - ukuhlolwa kwe-semiconductor, ukulungelelaniswa kwe-optical, ukulinganisa okudibeneyo, kunye neenkqubo zokuhamba ngomgca - edibene kwizinto ezimbini eziziphatha ngendlela eqikelelweyo kwizikali ze-micron kunye ne-sub-micron: i-precision granite kunye ne-precision ceramic. Ukuqonda indlela ezi zinto ezisebenza ngayo ngokwenene, kunye nendlela umgangatho wokuvelisa oqinisekiswa ngayo, kubalulekile ngaphambi kokuba uzibophelele kumthengisi.
Kutheni Uzinzo lwezinto ezibonakalayo luchonga ukuchaneka komlinganiselo
Yonke inkqubo yokulinganisa ichanekile kuphela njengesiseko ehleli kuso. I-CMM, umgca wokuhlola we-AOI, okanye inqanaba lokuphatha i-wafer lingachazwa njenge-sub-micron repeability - kodwa ukuba i-base plate iyakhula, iyafinyela, okanye ivakala ngendlela eyahlukileyo kunokuba bekulindelwe, loo repeability iyanyamalala ekusebenzeni.
Ukwandiswa kobushushu: I-Hidden Variable
Ukwanda kobushushu kudla ngokungathathelwa ngqalelo ngexesha lokukhethwa kwezixhobo, kodwa kudla ngokuba yeyona nto inegalelo elikhulu ekutshintsheni komlinganiselo wexesha elide.
- • I-granite emnyama idla ngokubonisa i-coefficient of thermal expansion (CTE) kuluhlu olumalunga ne-5–8 × 10⁻⁶/°C, kuxhomekeke kulwakhiwo lweeminerali kunye noxinano. I-granite emnyama enoxinano oluphezulu (≈3,100 kg/m³) ikwicala elizinzileyo ngakumbi lolu luhlu xa ithelekiswa ne-marble enoxinano oluphantsi okanye ii-granite substitutes ngamanye amaxesha ezichazwa njengezilinganayo.
- • Iiceramics ezichanekileyo (ezifana neefomyula ezisekelwe kwi-alumina) ngokubanzi zibonisa amaxabiso e-CTE alinganayo okanye aphezulu kancinci, kodwa zidibanisa oku nobunzima obungaqhelekanga kunye nokufunxwa komswakama okuphantse kungabikho, okwenza zifaneleke kakuhle kwiindawo zokucoca kunye neendawo ze-semiconductor apho ukuhambelana kobukhulu phantsi kobushushu obulawulwayo kubalulekile.
- • Xa kuthelekiswa, i-CTE yentsimbi (~11–13 × 10⁻⁶/°C) kunye ne-aluminium (~23 × 10⁻⁶/°C) zenza zombini ezi zinto zibe novelwano olukhulu kubushushu bemihla ngemihla kunye nokuguquguquka kwexesha lonyaka okuqhelekileyo kwiindawo ezininzi zemveliso.
Kwizicelo apho ukujika kwe-1°C kungafanele kuguqulele kwimpazamo enokulinganiswa, i-granite kunye ne-ceramic substrates zibonelela ngenzuzo yesakhiwo apho ezinye iindlela zesinyithi zingenakulingana.
Ukuqina kunye nokumelana nokunxiba
- • Igranite idla ngokuba phakathi kweMohs 6 kunye ne-7, nto leyo eyinika ukumelana okukhulu nokukrweleka komphezulu kunye nokuguguleka ngenxa yokudibana kwezixhobo ngokuphindaphindiweyo okanye ukulayisha izinto zokusebenza.
- • Iiseramikhi zobunjineli zinokufikelela kwi-Mohs 8–9, zisondela kubunzima bezixhobo ezininzi zokusika — isizathu esiphambili sokuba izinto zeseramikhi zichazwe kwizicelo zonxibelelwano oluhamba ngesantya esiphezulu, ezifana neeprobe zokulinganisa, iindlela zokuqondisa, kunye neepleyiti zokuguguleka.
- • Zombini ezi zinto azigugi kwaye aziguquguquki ngokwemilinganiselo phantsi komthwalo oqhubekayo woomatshini, ngokungafaniyo neentsimbi ezithambileyo ezinokuphuhla ukuguquka komphezulu ngokuhamba kwexesha.
Iimpawu ezingezizo zeMagnetic, ezingaziqhubiyo
I-granite okanye i-ceramic yobugcisa ayisebenzi ngemagnethi okanye ngombane, nto leyo eyimfuneko engenakuphikiswana ngayo:
- Iitafile zokulungelelanisa ezibonakalayo neze-laser, apho ukuphazamiseka kwemagnethi kunokuchaphazela ukufundwa kwenzwa
- Iiplatifomu zovavanyo kunye nokuhlolwa kwee-semiconductor, apho ukuhanjiswa kwe-due conductivity kubeka emngciphekweni umonakalo wezixhobo
- Cwangcisa iziseko zomatshini wokulinganisa, apho ungcoliseko lwemagnethi lunokukhetha iiprobe ezichanekileyo
Imigangatho Yokuvelisa Ebalulekileyo Ekusayinweni kweQC
Iimpawu zethiyori zezinto ezibonakalayo ziguqulela kuphela ekuchanekeni kwehlabathi lokwenyani ukuba inkqubo yokuvelisa nokuhlola ihlangabezana nemigangatho eyaziwayo yamazwe ngamazwe. Xa kuvavanywa umthengisi, iinjineli ze-QC kufuneka zijonge ngokukodwa oku kulandelayo:
- • Ukuthobela imigangatho evunyiweyo yokuba tyaba kunye nomphezulu, efana ne-DIN 876 (eJamani), i-ASME B89 series (e-USA), i-JIS B (eJapan), i-GB (eTshayina), kunye ne-BS 817-1983 (e-UK). Ababoneleli ababhekisa kwimigangatho emininzi yamazwe ngamazwe — endaweni yommandla omnye — bahlala bebonisa amava abanzi kwimarike yokuthumela ngaphandle kunye neenkqubo zangaphakathi ze-QC ezingqongqo.
- • Ukulinganisa okulandelekayo — izixhobo zokuhlola ezisetyenziselwa ukuqinisekisa ukuba zithe tyaba, ukufana, kunye nokugqitywa komphezulu kufuneka zithwale izatifikethi zokulinganisa ezilandelekayo kwiziko le-metrology elaziwayo, kungekuphela nje ireferensi yangaphakathi yefektri.
- • Iinkqubo zolawulo lomgangatho ezibhaliweyo, ngakumbi i-ISO 9001 (ulawulo lomgangatho), i-ISO 14001 (ulawulo lokusingqongileyo), kunye ne-ISO 45001 (impilo nokhuseleko emsebenzini), kunye nophawu lwe-CE kwiindidi zezixhobo ezifanelekileyo.
- • Iindawo zokuhlola ezilawulwa bubushushu. Ukulinganiswa kobuthebelele kunye nokulinganisa okufanayo okuthathwa ngaphandle kwegumbi elizinzileyo bubushushu akuthembekanga kangako, kuba indawo yokulinganisa ngokwayo ingenisa umahluko wobushushu kwisiphumo.
Ingxaki Eqhelekileyo Yokufumana Izinto: I-Marble Ethengiswa Njenge-"Granite"
Enye ingxaki ephindaphindayo yomgangatho kwikhonkco lobonelelo lwehlabathi kukutshintshwa kwe-marble enoxinano oluphantsi endaweni ye-granite yokwenyani, ethengiswa phantsi koluhlu oluqhelekileyo lwe-"granite base". Ngenxa yokuba i-marble inoxinano oluphantsi kunye nesakhiwo sekristale esahlukileyo, ihlala inika ukuqina okuphantsi, ukuvuleka okukhulu, kunye nozinzo olunciphileyo lwexesha elide xa kuthelekiswa ne-granite emnyama enoxinano oluphezulu. Ukucela iinkcukacha zoxinano lwezinto (kwaye, apho kunokwenzeka, ukuqinisekiswa komntu wesithathu) linyathelo elilula kodwa elisebenzayo lokunyamekela ngexesha lokufaneleka komthengisi.
Ukukhetha Phakathi kweGranite kunye neCeramic kwisicelo sakho
Akukho nanye kwezi zinto "ingcono" ngokubanzi — ukhetho olufanelekileyo luxhomekeke kwimeko yokusebenza:
- • I-granite idla ngokukhethwa kwiziseko ezinkulu zesakhiwo, iibhedi zoomatshini, kunye neepleyiti zomphezulu apho ubunzima, ukuxinana kokungcangcazela, kunye nokusebenza kakuhle kweendleko kwinqanaba eliphambili kubaluleke kakhulu - umzekelo, iziseko ze-CMM, iiplatifomu ze-linear motor, kunye neebhodi zesonka ze-optical.
- • I-ceramic idla ngokuba yeyona ifanelekileyo kwiindawo ezincinci, ezigugileyo, okanye ezibaluleke kakhulu kwigumbi lokucoca — ezinje ngee-probes zokulinganisa, izinto zesikhokelo, kunye neendawo zokuphatha ze-semiconductor — apho ubulukhuni, ukungangeni kweekhemikhali, kunye nokuveliswa kwee-particle eziphantse zibe zezona ziphambili.
Kwiinkqubo ezininzi eziphambili, ezi zinto zimbini zisetyenziswa kunye: isiseko sesakhiwo segranite esidityaniswe nemiphezulu yokuguguleka kweseramikhi okanye izinto zokulinganisa, ezidibanisa ukufuma kunye neenzuzo zobunzima begranite kunye nobunzima kunye nokucoceka kweseramikhi.
Isiphelo
Ukukhetha izinto ezisisiseko zezixhobo ezichanekileyo akusoloko kuyisigqibo soomatshini nje — sisigqibo sokuchaneka kwexesha elide. Uzinzo lobushushu, ubulukhuni, iipropati ezingezizo zemagnethi, kunye nemigangatho yokuvelisa enokungqinisiseka zonke ezi zinto zigqiba ukuba inkqubo igcina unyamezelo lwayo olulinganisiweyo kangangeminyaka, okanye iphuma kancinci kancinci kwisithuba seenyanga emva kokufakwa.
Kwiinjineli ze-QC kunye namaqela okuthenga avavanya ababoneleli, imibuzo ephambili ihlala ihambelana: Ingakanani i-density yezixhobo? Yeyiphi imigangatho yamazwe ngamazwe umenzi ayivavanyayo? Ngaba ukulinganiswa kuyalandeleka kwiziko elaziwayo? Kwaye ngaba ukugqitywa komphezulu kwenziwe zizixhobo kunye neengcali ezinamava aneleyo okugcina ukunyamezelana kwe-micron rhoqo kulo lonke ixesha lemveliso?
