Ezweni lobunjiniyela bokunemba kanye ne-metrology, ipuleti lobuso liyisisekelo esithule lapho kwakhiwa khona konke ukunemba. Kungakhathaliseki ukuthi lisetshenziselwa ukuhlolwa ngesandla ngama-height gauges noma njengesisekelo soMshini Wokulinganisa Ohlanganisiwe oyinkimbinkimbi (i-CMM), ipuleti lobuso linikeza indawo ebalulekile yokubhekisela eyenza ukulinganisa okunembile kube nokwenzeka. Kodwa-ke, ukunemba kwepuleti lobuso akuyona ikhwalithi ehlala njalo; yisimo okumele sigcinwe ngokucophelela ngokuhlanganiswa kokusetshenziswa okufanele, ukulawulwa kwemvelo, kanye nokulinganiswa okuvamile. Lesi sihloko sihlola izici ezibalulekile ezithonya ukunemba kwamapuleti obuso obunembile futhi sinikeza umhlahlandlela ophelele wemikhuba emihle yokugcina ubuqotho bawo endaweni yokukhiqiza noma yelabhorethri.
Isici esibaluleke kakhulu ekugcineni ukunemba kwepuleti lobuso ukuhlanzeka. Endaweni yokukhiqiza, amapuleti obuso ahlala evezwa uthuli, ama-chips ensimbi, uwoyela, nezinye izinto ezingcolisayo. Ngisho nenhlayiya encane kakhulu ye-grit ingasebenza njengento eklwebhayo, ibangele ukuguguleka ebusweni bepuleti kanye nesisekelo sezinto zokulinganisa ezisetshenziswa kulo. Ngokuhamba kwesikhathi, lokhu kuguguleka kungaholela “ezindaweni eziphansi” ezibeka engcupheni ukuthamba kwepuleti. Ukuvimbela lokhu, amapuleti obuso kufanele ahlanzwe njalo kusetshenziswa isihlanzi sepuleti lobuso esikhethekile. Laba bahlanzi benzelwe ukususa uwoyela nokungcola ngaphandle kokushiya insalela noma ukuthinta izakhiwo zetshe. Kubalulekile futhi ukusula ipuleti ngaphambi nangemva kokusetshenziswa ngakunye, nokuyigcina imbozwe nge-vinyl evikelayo noma isembozo sokhuni uma ingasebenzi.
Izinto zepuleti elingaphezulu ngokwalo zidlala indima ebalulekile ekunembeni kwalo kwesikhathi eside. Nakuba amapuleti angaphezulu ensimbi ayeyindinganiso, i-granite isibe yinto ethandwayo kakhulu ezisetshenziswa kakhulu zesimanje. I-Granite inikeza izinzuzo eziningana, okuhlanganisa ubulukhuni obuphezulu, ukudambisa ukudlidliza kwemvelo, kanye nokumelana nokugqwala. Ngaphezu kwalokho, i-granite ayithinteki kakhulu yizinguquko zokushisa kune-cast iron. Kodwa-ke, akuwona wonke ama-granite adalwe ngokulinganayo. Amapuleti angaphezulu asezingeni eliphezulu ngokuvamile enziwa nge-black diabase noma ezinye izinhlobo ze-granite eziqinile, ezicolekile ezinikeza inhlanganisela engcono kakhulu yokuqina nokuzinza. Ukuqonda izakhiwo ze-granite ethile esetshenziswa epuletini elingaphezulu kubalulekile ekubikezeleni ukuthi izosabela kanjani ezicini zemvelo kanye nokuguguleka ngokuhamba kwesikhathi.
Ukulawulwa kwemvelo mhlawumbe kuyisici esibaluleke kakhulu, kodwa esivame ukunganakwa, ekugcineni ukunemba kokulinganisa. Ukushintshashintsha kwezinga lokushisa kuyisitha esiyinhloko sokunemba. Ngisho noma i-granite inomthamo ophansi wokwanda kokushisa, ipuleti elikhulu elingaphezulu lisengabhekana nezinguquko ezinkulu zobukhulu uma izinga lokushisa lingalawulwa. Okungcono kakhulu, ilebhu ye-metrology kufanele igcinwe kuma-degree Celsius angama-20 alinganayo, okuyindinganiso yamazwe ngamazwe yokulinganisa ubukhulu. Okubaluleke kakhulu, izinga lokushisa kumele lifane kulo lonke ipuleti. Uma uhlangothi olulodwa lwepuleti lufudumele kunolunye—mhlawumbe ngenxa yokusondela efasiteleni noma emthonjeni wokushisa—ipuleti lingagoba noma ligobe, okuholela emaphutheni amakhulu okulinganisa. Ukulawulwa komswakama nakho kubalulekile, njengoba izinguquko ezinkulu kumswakama zingathinta ukuzinza kwe-granite kanye nokusebenza kwezinsimbi zokulinganisa ze-elekthronikhi.
Indlela ipuleti elingaphezulu elisekelwa ngayo ingenye into ebalulekile ekunembeni kwalo. Ipuleti elingaphezulu alilona umzimba oqinile ngokuphelele; lizophambuka ngaphansi kwesisindo salo kanye nesisindo sezingxenye ezilinganiswayo. Ukuze kuncishiswe lokhu kuphambuka, amapuleti angaphezulu kufanele asekelwe ezindaweni ezithile, ezaziwa ngokuthi amaphuzu e-Airy, aklanyelwe ukuhlinzeka ngokulungiselelwa okuzinzile nokuyisicaba. Amapuleti amaningi angaphezulu afika nesitendi esizinikele esenzelwe ukusekela ipuleti kula maphuzu. Kubalulekile ukuthi isitendi sibe sezingeni elifanele nokuthi ipuleti lingaphazanyiswa yinoma yikuphi ukusonteka noma ukungalingani kwamandla. Ukuhlola njalo izinga lesitendi nokuqinisekisa ukuthi amaphuzu okusekela alungiswe kahle kuyingxenye ebalulekile yokugcinwa kwepuleti elingaphezulu.
Ukulinganisa kuyindlela kuphela yokuqinisekisa ukunemba kwepuleti lobuso nokubona noma yikuphi ukuguguleka okwenzekile. Ukulinganisa okuphelele kuhilela ukulinganisa kokubili ukuguguleka kwepuleti kanye nokuphindaphinda kwalo. Ukuguguleka kuvame ukulinganiswa kusetshenziswa i-laser interferometer noma izinga le-elekthronikhi, elibala yonke indawo yepuleti ukuqinisekisa ukuthi ihlangabezana nezinga elidingekayo (njengeBanga AA, A, noma B). Ngakolunye uhlangothi, ukuphindaphinda kulinganiswa kusetshenziswa i-repeat-o-meter enembile kakhulu, ehlola ukuguguleka kwendawo ngokuhambisa isibonakaliso esibucayi phezu kobuso. Ukulinganisa kufanele kwenziwe ngezikhathi ezijwayelekile, ngokuvamile njalo ezinyangeni eziyisithupha kuya kweziyishumi nambili, kuye ngokuthi ukusetshenziswa kaningi kangakanani kanye nezinga elidingekayo lokunemba. Umbiko wokulinganisa oqinisekisiwe unikeza ukulandeleka okudingekayo kanye nokuqiniseka ukuthi ipuleti lobuso lifanele injongo yalo ehlosiwe.
Amasu okusebenzisa kahle nawo abalulekile ekulondolozeni impilo yepuleti elingaphezulu. Esinye sezimbangela ezivame kakhulu zokuguguleka kwangaphambi kwesikhathi ukusetshenziswa okuphindaphindiwe kwendawo efanayo yepuleti. Ukuvimbela lokhu, abaqhubi kufanele bakhuthazwe ukusebenzisa lonke ubuso bepuleti, bejikeleza isethaphu futhi behambisa izinsimbi zokulinganisa ezindaweni ezahlukene. Ngaphezu kwalokho, izingxenye ezisindayo kufanele zehliswe epuletini ngobumnene ukuze kugwenywe umonakalo wokushayisana, okungabangela “ukulimaza” noma ukuqhekeka kwe-granite. Uma usebenzisa ama-height gauges noma ezinye izinsimbi, kubalulekile ukuqinisekisa ukuthi izisekelo zazo zihlanzekile futhi azinawo ama-burrs, njengoba noma yikuphi ukuklwebheka kungaklwebha ubuso bepuleti.
Ekuphetheni, ukunemba kwepuleti lobuso elinembile kuwumphumela wendlela ephelele yokulungisa nokulawula imvelo. Ngokugcina ipuleti lihlanzekile, ukulawula izinga lokushisa nomswakama, ukunikeza ukwesekwa okufanele, nokunamathela esimisweni sokulinganisa esivamile, abakhiqizi bangaqinisekisa ukuthi isisekelo sabo sokubhekisela sihlala sithembekile iminyaka ezayo. Ukutshalwa kwezimali epuletini lobuso elisezingeni eliphezulu kumane kuyisiqalo; inani langempela litholakala ngokusebenzisa ngenkuthalo imikhuba emihle evikela ukunemba kwayo. Njengoba isidingo sokubekezelelana okuqinile kanye nekhwalithi ephezulu siqhubeka nokukhula, indima yepuleti lobuso njengesisekelo se-metrology izobe ibaluleke kakhulu, okwenza ukulungiswa kwayo kube yinto eza kuqala kunoma iyiphi inhlangano egxile ekunembileni.
Indima yepuleti elingaphezulu komongo obanzi wesistimu yokuphatha ikhwalithi nayo ifanelekile ukucatshangelwa. Ezimbonini eziningi, njengokukhiqiza izindiza kanye namadivayisi ezokwelapha, ikhono lokubonisa ukunemba kokulinganisa liyimfuneko yokulawula. Ipuleti elingaphezulu elinakekelwa kahle futhi elilinganiswe njalo liyingxenye ebalulekile yalokhu kuboniswa. Imibhalo enikezwe yimibiko yokulinganisa isebenza njengerekhodi lokusebenza kwepuleti ngokuhamba kwesikhathi, okuvumela ukuhlonza izitayela kanye nokubikezela ukuthi ipuleti lingadinga nini ukuvuselelwa noma ukushintshwa. Le ndlela yokulungisa ayigcini nje ngokuqinisekisa ukunemba kokulinganisa kwamanje kodwa futhi ihlinzeka ngezinga lokuphathwa kwezingozi elibalulekile ezindaweni zokukhiqiza ezisengozini enkulu.
Ngaphezu kwalokho, ukuqeqeshwa kwabasebenzi abasebenzisana namapuleti obuso kuyisici esibalulekile esivame ukunganakwa. Abasebenzi kumele baqaphele ukuzwela kwemishini kanye nomthelela izenzo zabo ezingaba nawo ekunembeni kwayo. Lokhu kuhlanganisa ukuqonda ukubaluleka kokuhlanza ipuleti ngaphambi kokusebenzisa, indlela efanele yokuphatha nokubeka izingxenye, kanye nesidingo sokubika noma yimuphi umonakalo ongengozi noma ukufundwa okungavamile. Isiko lokunakekela nokuhlonipha imishini enembile kungenye yezindlela eziphumelela kakhulu zokugcina ukunemba kwesikhathi eside kwepuleti lobuso. Izikhathi zokuqeqesha ezivamile kanye nokuxhumana okucacile ngezinqubo zokulungisa kungasiza ekuqinisekiseni ukuthi wonke umuntu elabhorethri noma esitolo usebenza emgomweni ofanayo wokulinganisa ubuhle.
Indawo ebonakalayo yepuleti elingaphezulu ngaphakathi kwesikhungo ingaba nomthelela omkhulu ekusebenzeni kwalo. Ngale kwesidingo esisobala sendawo elawulwa yisimo sezulu, ipuleti kufanele libe kude nemithombo yokudlidliza, njengemishini esindayo, izindawo zokulayisha, noma izindawo ezinabantu abaningi. Ngisho nokudlidliza okuncane kungaphazamisa izilinganiso ezinembile kakhulu, ikakhulukazi uma kusetshenziswa izinkomba ezibucayi noma amazinga kagesi. Kwezinye izimo, kungadingeka ukufaka ipuleti elingaphezulu esisekelweni esikhethekile, esihlukanisiwe nokudlidliza ukuqinisekisa izinga elidingekayo lokuzinza. Ngaphezu kwalokho, ipuleti kufanele ligcinwe kude nokukhanya kwelanga okuqondile kanye nezindawo zomoya ezipholile, njengoba lokhu kungadala amazinga okushisa asendaweni aholela ekugobeni.
Njengoba ubuchwepheshe buqhubeka nokuthuthuka, amathuluzi asetshenziselwa ukulinganisa nokuqapha amapuleti obuso nawo aya ngokuya eba yinkimbinkimbi. Amazinga kagesi angenantambo kanye nezinhlelo zokumapha ezisekelwe ku-laser zivumela ukulinganisa okusheshayo nokunembile, okunikeza isithombe esinemininingwane eminingi ngesimo sobuso bepuleti. Amanye amapuleti obuso besimanje afakwe ngisho nezinzwa ezifakiwe ezingaqapha izinga lokushisa nokudlidliza ngesikhathi sangempela, zinikeze isixwayiso sokuqala uma izimo zemvelo ziwela ngaphandle kobubanzi obamukelekayo. Lawa mapuleti obuso “ahlakaniphile” amelela isinyathelo esilandelayo ekuguqukeni kwe-metrology, enikeza izinga lokuqonda nokulawula okwakungenakwenzeka ngaphambili.
Inqubo yokuvuselela ipuleti elingaphezulu eligugile ingenye isici esibalulekile somjikelezo walo wokuphila. Lapho ipuleti lingasahlangabezani nezidingo zalo zokusicaba noma zokuphindeka, livame ukubuyiselwa ngenqubo yokugoqa. Lokhu kuhilela ukusebenzisa amakhemikhali ahuzukayo namathuluzi akhethekile ukususa izinto ngesandla ezindaweni eziphakeme kuze kube yilapho ipuleti liphinde lisicaba. Ukuvuselela ipuleti kuwumsebenzi onekhono eliphezulu okufanele wenziwe kuphela ochwepheshe abanolwazi. Ipuleti elivuselelwe kahle lingaba nembambo njengelisha, linikeze indlela engabizi yokwandisa impilo yempahla ebalulekile. Kodwa-ke, kunomkhawulo wokuthi ipuleti lingavuselelwa kangaki ngaphambi kokuba libe mncane kakhulu noma ubuqotho besakhiwo salo bube sengozini, lapho kufanele lishintshwe khona.
Emakethe yomhlaba wonke, ukunamathela ezindinganisweni zamazwe ngamazwe zamapuleti obuso, njenge-ISO 8512 noma i-ASME B89.3.7, kubalulekile ukuqinisekisa ukuhambisana nokuthembeka kwezilinganiso kuzo zonke izikhungo namazwe ahlukene. Lezi zindinganiso zichaza izidingo zezinto ezibonakalayo, ukwakheka, kanye namazinga okunemba, okunikeza ulimi oluvamile kubakhiqizi kanye nochwepheshe be-metro. Uma uthenga ipuleti lobuso elisha noma une-ekhona elinganisiwe, kubalulekile ukuqinisekisa ukuthi umsebenzi wenziwa ngokuhambisana nalezi zindinganiso. Lokhu akugcini nje ngokuqinisekisa ikhwalithi yepuleti kodwa futhi kwenza kube lula ukushintshana kwezingxenye nedatha ezweni elixhumene kakhulu.
Ngamafuphi, ukugcinwa kwepuleti lobuso obunembile kuyinqubo eqhubekayo edinga ukunakwa kwemininingwane kanye nokuzibophezela ekhwalithini. Kusukela enkambisweni yansuku zonke yokuhlanza nokumboza ipuleti kuya emisebenzini yezikhathi ezithile yokulinganisa nokulungisa ubuso, yonke into ethathwayo ukuvikela ubuqotho bepuleti inegalelo ekunembeni okuphelele kwenqubo yokukhiqiza. Ngokuqonda izici ezibalulekile ezithonya ukusebenza kwepuleti lobuso—ukuhlanzeka, izakhiwo zezinto ezibonakalayo, ukulawulwa kwemvelo, ukwesekwa okufanele, kanye namasu okusebenzisa—abakhiqizi bangakha isisekelo esiqinile semisebenzi yabo yokukala. Njengoba sisondela enkathini yokunemba okukhulu kanye nokwenza izinto ngokuzenzakalela, ipuleti lobuso elithobekile lizohlala liyithuluzi elibalulekile, elisebenza njengereferensi yokugcina yekhwalithi kanye nobuhle bemikhiqizo esiyidalayo. Ukuphishekela ukunemba kuqala ebusweni, futhi ukugcinwa kwalo kuyisihluthulelo sokuvula amandla aphelele obunjiniyela besimanje.
