Kwihlabathi elinobunkunkqele be-metrology yemizi-mveliso, ukufuna indawo yokulinganisa egqibeleleyo yimfazwe eqhubekayo nxamnye nefiziksi. Nangona i-granite ibisoloko ingumgangatho woshishino wozinzo, iimfuno eziguqukayo zokuvelisa ngesantya esiphezulu, iindawo zobushushu obugqithisileyo, kunye nokuhlolwa komgangatho wevenkile enzima kuye kwavula indlela yoguquko lwezinto ezimbini. Namhlanje, indibaniselwano yeqhinga le-Advanced Ceramic & Cast Iron Measurement Tools imele incopho yobunjineli, apho ukuqina okuqinileyo kudibana nokuchaneka okungagungqiyo. Olu manyano lunika abavelisi izixhobo eziguquguqukayo ezinokukwazi ukuhamba kwiindawo zemveliso ezinzima kakhulu.
Ukuhlaziywa kwesinyithi esityhidiweyo: Amandla emizi-mveliso aphinde acingelwa
Kangangeminyaka engaphezu kwekhulu, isinyithi esityhidiweyo sasingukumkani ongenakuphikiswa kwivenkile yoomatshini. Nangona kunjalo, njengoko izinto ezenziweyo kunye namatye ayethandwa kakhulu, abanye babejonga isinyithi njengento eyayisele isetyenzisiwe kwixesha elidlulileyo. Loo mbono itshintshe kakhulu. Isinyithi esityhidiweyo senqanaba le-metrology yanamhlanje, ngakumbi isinyithi esingwevu esixineneyo okanye isinyithi esithambileyo, siye savuselelwa ngobuchwepheshe.
Eyona nto iphambili enomtsalane wesinyithi esityhidiweyo ikwimo yayo yokwakheka kunye neempawu zokudambisa ukungcangcazela. Kwiindawo apho oomatshini abanzima basebenza khona kufutshane, ulwakhiwo lwendalo lwesinyithi esityhidiweyo lusebenza njenge-buffer, lufunxa ukungcangcazela okunokuthi kuphazamise imilinganiselo ebuthathaka. Ngaphezu koko, ngokungafaniyo nelitye, isinyithi esityhidiweyo sinomlinganiselo wokuqina. Oku kuyenza ibe lolona khetho lufanelekileyo kwizicelo ezinzima ezifana nokuhlolwa kwe-motor block okanye umsebenzi wezixhobo ezinkulu kunye ne-die, apho umphezulu kufuneka umelane nobunzima obukhulu kunye nempembelelo ngamanye amaxesha ngaphandle kokuqhekeka.
Ukuze kufezekiswe “ukuchaneka” okuthenjiswe kwisihloko sethu, ezi zixhobo zidlula kwinkqubo enzima yokunonga. Ii-castings eziluhlaza zihlala zishiywa ukuba ziguge ngokwendalo okanye zifakwe kwi-thermal cycling ukuze kuncitshiswe uxinzelelo lwangaphakathi. Oku kuqinisekisa ukuba xa umphezulu ukhuhlwe okanye ucoliwe ukuya kutsho kwiBanga 0 okanye kwiBanga 1, uhlala uzinzile ngokwemilinganiselo amashumi eminyaka. Impendulo echukumisekayo yomphezulu wesinyithi okhuhlwe ngesandla—ophawulwa ngamawaka eepokotho ezincinci ezigcina ioyile—isajongwa ziingcali zobugcisa njengomgangatho wegolide “wokusonga” iindawo nokuqinisekisa ukuhamba okugudileyo nokuchanekileyo kweegeyiji.
Iiceramics eziPhambili: Umda Omtsha weMetrology
Kwelinye icala, iiseramikhi eziphambili (ezidla ngokuba yiAlumina okanye iSilicon Carbide) zimele umda "wetekhnoloji ephezulu" wokulinganisa kwanamhlanje. Ukuba isinyithi esityhidiweyo sinamandla kakhulu kwigumbi levenkile, iiseramikhi zezona zibalaseleyo kwilebhu nakwigumbi lokucoca.
Iiseramikhi zibonelela ngeempawu ezibonakalayo ezingaqhelekanga xa zithelekiswa neentsimbi zemveli. Okokuqala nokubalulekileyo bubulukhuni bazo obugqithisileyo. Izixhobo zeseramikhi eziphambili ziqine njengeedayimani, nto leyo ezenza zingabi nakukrweleka nokuguguleka. Kwimeko yemveliso eninzi apho kusetyenziswa izixhobo izihlandlo ezingamawaka ngemini, ubude begauge yeseramikhi abunakuthelekiswa nanto.
Mhlawumbi okubaluleke ngakumbi, iiseramikhi zijongana nomlinganiselo ochanekileyo we-Achilles' heel: ukwanda kobushushu. Iiseramikhi eziphambili zine-coefficient yokwanda kobushushu ephantsi kakhulu kunentsimbi okanye isinyithi, kwaye kwezinye iimeko, ingaphantsi kunegranite. Oku kuvumela ukulinganiswa okuchanekileyo kakhulu kwiindawo apho ulawulo lobushushu lungagqibelelanga. Ngaphezu koko, iiseramikhi azinazo iimbobo kwaye azinazo iikhemikhali. Azigqwali, azidli mhlwa, kwaye azifuni ioyile yokukhusela efunekayo kwisinyithi. Oku kuzenza zibe lolona khetho lukhethwayo kumashishini e-semiconductor kunye nezixhobo zonyango, apho ungcoliseko luyinto ebalulekileyo.
Ukusebenzisana Kokukhetha: Kutheni Ukuqina Nokuchaneka Kufuneka Kuhlale Kunye
Umenzi wanamhlanje akasafuni isisombululo "esifanela wonke umntu". Endaweni yoko, ingqwalasela itshintshele ekukhetheni izixhobo ezifanelekileyo zesicelo esithile. Ngokunikezela ngezixhobo zokulinganisa zeCeramic kunye neCast Iron eziPhambili, ababoneleli bavumela iinjineli ukuba zilinganisele izikali zokuqina kunye nokuchaneka.
Umzekelo, indawo yokulungisa iinqanawa okanye indawo yokuhlanganisa iimoto inokuxhomekeka kwiipleyiti ezinkulu zesinyithi kunye nemiphetho ethe tye ngenxa yobunzima bazo obukhulu kunye nokumelana nobunzima bokusetyenziswa kakhulu kwimizi-mveliso. Okwangoku, ilebhu yokulinganisa ngaphakathi kweso sakhiwo sinye iya kusebenzisa izikwere ezinkulu zeceramic kunye neesilinda ukuqinisekisa ukuchaneka kweegeyiji zazo eziphathwayo.
Ukuqina kwentsimbi ephosiweyo kuqinisekisa ukuba isiseko sokulinganisa asikaze sonakaliswe kukusilela kwesakhiwo, ngelixa ukuchaneka kweeseramikhi kubonelela ngendawo yokubhekisa ephantse igqibelele engachaphazeleki yimeko-bume. Le ndlela "yokungakholelwa kwizinto ezibonakalayo" kwi-metrology yiyo echaza ixesha langoku lolawulo lomgangatho. Akusekho malunga nokuba zeziphi izinto "ezingcono," kodwa endaweni yoko, indlela iimpawu ezizodwa zento nganye ezingasetyenziswa ngayo ukuphelisa ukungaqiniseki kokulinganisa.
Ukuhlangabezana neMfuno yeHlabathi yoBuchule beZinto eziBalulekileyo
Njengoko uthotho lwezinto ezibonelelwayo kwihlabathi liphela lusiba nzima ngakumbi, imfuno yezi zixhobo zikhethekileyo iye yanda kumazwe ngamazwe. Abathumeli bamanye amazwe bafumanisa ukuba iimarike eYurophu naseMntla Melika zikhangela ngakumbi izisombululo "zezinye izinto". Nokuba yibhloko ye-V yeseramikhi engasetyenziswa ngaphakathi kwigumbi lokutshiza okanye ipleyiti yokumakisha yesinyithi esisetyenziswa rhoqo kwiziko elitsha leenqwelo moya, imfuneko yoxwebhu olukumgangatho ophezulu kunye nesiqinisekiso samazwe ngamazwe isabalulekile.
Zonke izixhobo, nokuba yintsimbi okanye yiceramic, kufuneka zihambisane nohlobo oluqinileyo lwemvelaphi. Oku kuquka iingxelo ze-laser interferometry ezibonisa i-topography yomphezulu ngaphakathi kwenxalenye yobude bokukhanya. Kwimarike yehlabathi, "ukuchaneka" akuyonto ibango—liyinyani ebhaliweyo.
Isiphelo: Ikamva linezinto ezininzi
Isihloko esithi “Izixhobo zokulinganisa iCeramic kunye neCast Iron eziPhambili: Ukuqina Kudibana nokuchaneka” singaphezulu nje kwesiqubulo sokuthengisa; sisisikhokelo sekamva loshishino. Ngokushiya imida yento enye, abavelisi banokwakha iinkqubo zokuhlola ezikhawulezayo, ezichanekileyo, neziqinileyo ngakumbi.
Njengoko sijonge kwikamva le-Industry 4.0, apho izinzwa ezizenzekelayo kunye neerobhothi zithatha khona umsebenzi onzima wokuhlola, izixhobo ezibonakalayo—iireferensi eziphambili—kufuneka zithembeke ngakumbi kunangaphambili. Nokuba kukuthembeka kwexesha elide kwesinyithi esitshisiweyo okanye ukusebenza kwexesha elide kweeseramikhi zobugcisa, ezi zixhobo zibonelela “ngenyaniso esisiseko” kwihlabathi ledijithali. Ekufuneni ukugqibelela, ihlabathi le-metrology lifumanise ukuba iziseko eziqinileyo zakhiwe ngezinto ezahlukeneyo, ngasinye sidlala indima yaso ekufuneni ukuchaneka kwehlabathi.
