Ezweni le-metrology kanye nokuhlolwa okunembile, i-Coordinate Measuring Machine (CMM) imele njengomlamuli wokugcina wekhwalithi. Kodwa-ke, ukunemba kwe-CMM akuyona nje umsebenzi wesofthiwe yayo noma izinzwa zayo; ngokuyinhloko kunqunywa isisekelo esingokoqobo lapho lezo zinzwa zihamba khona. Sekungamashumi eminyaka, onjiniyela kanye nochwepheshe bokuthenga bebebhekene nempikiswano ephindaphindayo: ingabe isisekelo somshini kufanele sakhiwe nge-granite enembile noma insimbi ephonswe ngendlela yendabuko?
Ukukhetha izinto ezifanele kuyisinqumo esibalulekile esithinta isikhathi eside somshini, ukusabela kwawo ezinguqukweni zemvelo, futhi ekugcineni, ukuthembeka kwedatha ekhiqizayo. Zombili izinto zisebenzele imboni yokukhiqiza iminyaka engaphezu kwekhulu, kodwa zinikeza izindlela zokuziphatha ezihluke kakhulu kwezemishini. Ukuqonda umehluko phakathi kwalezi "zinto ezisindayo" ezimbili kubalulekile kunoma yisiphi isikhungo esifuna ukuthuthukisa umnyango waso wokuhlola ukuze uvumelane nezidingo zokukhiqiza zanamuhla.
Inzuzo Yendawo Ye-Precision Granite
I-Granite isibe ukukhetha okuvelele kwezakhiwo zesimanje ze-CMM ezisezingeni eliphezulu, futhi ngesizathu esihle. Ngokombono ongokoqobo, i-granite emnyama ingenye yezinto ezizinzile kakhulu ezitholakala emvelweni. Amandla ayo ayinhloko atholakala ku-coefficient yayo yokwanda kokushisa, okuphansi kakhulu kunezinsimbi eziningi. Esikhungweni lapho izinga lokushisa lingalawulwa kahle kuze kube yingxenyana yezinga, isisekelo sensimbi sizokhula futhi sinciphe, okubangela ukuba i-geometry yokulinganisa ikhukhuleke. I-Granite ihlala ingasasebenzi kahle, iqinisekisa ukuthi "iphuzu lika-zero" lihlala lapho kufanele libe khona.
Ngale kokuqina kokushisa, i-granite ayigqwali futhi imelana ne-asidi ngokwemvelo. Ezindaweni eziningi zezimboni, umswakama noma umhwamuko wamakhemikhali ungaholela ekungcoleni ezindaweni zensimbi. Ngenkathi insimbi ephonswe idinga ukugcotshwa njalo nokugcinwa ukuze kuvinjelwe ukugqwala, i-granite idinga kuphela ukusula okulula ngesihlanzi esikhethekile. Ngaphezu kwalokho, i-granite ayisebenzi ku-magnetic. Kuma-CMM asetshenziswa ezindaweni ze-elekthronikhi noma ezizwela ku-magnetic, lesi yisici esibalulekile sokuphepha nokunemba.
Esinye sezici eziyingqayizivele ze-granite ukuthi “ayibhoboki”. Uma ipuleti lobuso be-granite noma isisekelo somshini sishaywa noma siqhekeka ngengozi, izinto azishisi “amakhowe” noma ziphakamise umugqa ozungeze indawo lapho kushayisana khona. Lokhu kusho ukuthi ukuthamba kwendawo yonke kuhlala kuphelele, kuvikela ama-air bearings kanye nokunemba kwebhuloho elihambayo.
Ifa Lensimbi Ebunjiwe
Nakuba i-granite ibusa imakethe ye-CMM, insimbi ephothiweyo isalokhu iyinto ebalulekile ezweni elibanzi lobunjiniyela obunembile kanye nokukhiqizwa okunzima. Insimbi ephothiweyo empunga esezingeni eliphezulu noma insimbi ephothiweyo iyindinganiso yegolide yemibhede yamathuluzi omshini kanye namapulatifomu amakhulu ezimboni. Isizathu sisekuqineni kwesakhiwo sayo kanye nekhono layo lokuphothwela ezimweni eziyinkimbinkimbi.
Amapulatifomu ensimbi ephothiwe anikeza izinga "lokuqina kwesakhiwo" i-granite engenakukwazi ukulilinganisa. Ezisetshenzisweni ezihilela izinto zokusebenza ezisindayo noma imithwalo enamandla kakhulu, insimbi ephothiwe ayinakuphuka kakhulu ngaphansi kokucindezeleka okukhulu. Yingakho amapulatifomu ensimbi ephothiwe evame ukusetshenziswa njengendawo yokuqala yokuhlanganisa nokuhlola ekukhiqizweni kwezimoto nezindiza. Ipulatifomu yensimbi ephothiwe esezingeni eliphezulu, enongiwe kahle futhi eklwebhe ngokunemba, inikeza indawo yokubhekisela engabhekana nobunzima bempilo yezimboni enzima ngenkathi igcina ubushelelezi obumangalisayo.
Ngaphezu kwalokho, insimbi ephothiwe ine-modulus ephezulu yokunwebeka, okwenza ibe yinhle kakhulu ezingxenyeni okumele zimelane nokuphambuka ngaphansi kwesisindo esinzima. Emisebenzini yokuhlola emikhulu lapho umsebenzi unesisindo samathani amaningana, ipulatifomu yensimbi ephothiwe eqinisiwe ivame ukuhlinzeka ngesakhiwo sokusekela esidingekayo uhlelo olusekelwe ngamatshe kuphela olungase lube nzima ukusifaka ngaphandle kobukhulu obukhulu.
Ukudambisa Nokudlidliza: Impi Ethule
Kunoma yiluphi uhlelo lokusebenza lwe-metrology, ukudlidliza kuyisitha. Kwethula umsindo kudatha futhi kungabangela izisusa ezingamanga kuma-touch probe abucayi. I-granite iyazigqaja ekuthobeni ukudlidliza okuvama kakhulu ngenxa yesakhiwo sayo sangaphakathi esiminyene, esinezimbobo, nesingafani. "Imunca" ngempumelelo amandla ephansi lesitolo, idale indawo ethule yokuthi ibhuloho lokulinganisa lisebenze.
Insimbi ephothiwe nayo inezimfanelo ezinhle zokudambisa—ingcono kakhulu kunensimbi—kodwa ivame ukusabela ngendlela ehlukile ekuphenduleni okuphansi kwemvamisa. Ezinhlelweni eziningi zokukhiqiza ezisezingeni eliphezulu, ikhambi elifanele akuyona ukukhetha eyodwa kunenye, kodwa ukuqonda ukuthi ngayinye ifanelana kuphi. Ukuze kube nokunyakaza okunembile kakhulu, okungaphansi kwe-micron kwebhuloho le-CMM, ukudambisa i-granite kuvame ukukhethwa. Endaweni esindayo, edlidlizayo yesikhungo somshini noma umugqa wokuhlanganisa, ukudambisa ubuningi kanye nokwangaphakathi kwepulatifomu yensimbi ephothiwe ngokuvamile kuyisinqumo esihle kakhulu.
Ukugcinwa, Isikhathi Eside, kanye Nokusebenza Kahle Kwezindleko
Ngokombono wokunakekelwa, i-granite iyona ephumelela kakhulu ekusetshenzisweni kwe-CMM. Ukumelana kwayo nokuguguleka kanye nezici zemvelo kusho ukuthi isisekelo se-granite singagcina sithambile amashumi eminyaka ngaphandle kokungenelela okuncane. Kodwa-ke, kubalulekile ukuqaphela ukuthi amapulatifomu ensimbi ancibilikisiwe anikeza inzuzo eyingqayizivele: angakwazi "ukulungiswa kabusha" ngokukhuhla ngesandla noma ukugaya kalula kwezinye izimo zezimboni ezinkulu.
Uma kuhlolwa izindleko, umuntu kufanele abheke "Izindleko Eziphelele Zobunikazi." Isisekelo se-granite singase sibe nezindleko eziphezulu zokuqala zezinto noma isisindo sokuthumela, kodwa ukuntuleka kwezidingo zokuvimbela ukugqwala kanye nokungavikeleki kwaso ekuwohlokeni kwemvelo kuvame ukwenza kube ngcono kakhulu eminyakeni engama-20 yokuphila. Ngokuphambene nalokho, ezindaweni zokuhlola ezinkulu phansi noma imisebenzi yokubeka ngesandla, amapulatifomu ensimbi ancibilikisiwe anikeza ukuqina okunikeza inani elingcono ezindaweni ezinabantu abaningi lapho itshe lingase lithambekele ekulimaleni komhlaba okuvela ezingxenyeni zensimbi esindayo.
Isiphetho: Ukukhetha Okufanele Isikhungo Sakho
Ukukhetha phakathi kwe-granite enembile ne-cast iron ekugcineni kuncike ekusetshenzisweni kwakho okukhethekile. Uma umgomo wakho uwukuhlola okusheshayo, okuzenzakalelayo okune-sub-micron elabhorethri elawulwayo, ukuzinza kanye nokufiphazwa kwesisekelo se-granite emnyama cishe akunakunqotshwa. Kuyinto yesikhathi esizayo ye-metrology enembile.
Kodwa-ke, umhlaba wezimboni usathembele kakhulu emandleni nasekusebenziseni izinto eziningi kwamapulatifomu ensimbi ensimbi ukuze ahlanganiswe, ahlelwe kahle, kanye namaphrojekthi amakhulu obunjiniyela. Zombili izinto ziyizinsika ezibalulekile zokukhiqiza zanamuhla. Ngokuqonda izinzuzo zokushisa ze-granite kanye nokuqina kwesakhiwo sensimbi ensimbi ensimbi, onjiniyela bangakha izinhlelo zokuhlola nezokukhiqiza ezingagcini nje ngokuba zinembile namuhla kodwa futhi ezizohlala zizinzile izizukulwane ezizayo. Kungakhathaliseki ukuthi ufaka i-CMM entsha noma uthuthukisa iphansi lakho lokuhlanganisa, ukukhetha izinto eziyisisekelo kuyisinyathelo esibaluleke kakhulu ekuqinisekiseni ubuqotho bomsebenzi wakho wobunjiniyela.
