Kwindawo yokuqinisekisa umgangatho ophezulu, iCoordinate Measuring Machine (CMM) imi njengoyena mgwebi wenyaniso. Nokuba iqinisekisa i-geometry entsonkothileyo ye-turbine ye-aerospace okanye imilo ethambileyo ye-implant yezonyango, i-CMM kufuneka inike imilinganiselo echanekileyo ngaphakathi kwenxalenye yeenwele zomntu. Ukuze kufezekiswe eli nqanaba lokusebenza, umatshini ufuna isiseko somzimba esikhuselekileyo kukuphazamiseka kwendalo. Yingakho i-granite emnyama iye yaba yinto ekhethwayo kwiindawo zokwakha ze-CMM zehlabathi.
Isiseko soZinzo lweMilinganiselo
Umceli mngeni ophambili kuyo nayiphi na i-CMM kukugcina i-geometry yayo ngokuhamba kwexesha nangaphantsi kweemeko ezahlukeneyo. Izixhobo zesinyithi, nangona zomelele, zisengozini yoxinzelelo lwangaphakathi kunye nokwanda okukhulu kobushushu. Ukuba ibhulorho okanye isiseko se-CMM siyanda okanye sigobe kancinci, yonke inkqubo yokulungelelanisa ilahleka ekulungelelaniseni.
I-granite emnyama, ingakumbi iintlobo ezinoxinano olukhulu ezifana ne-ZHHIMG Black Granite, inika isisombululo sendalo. Njengento echithe izigidi zeminyaka phantsi komhlaba, ngokwendalo "iyathomalalisa uxinzelelo." Ayinayo "inkumbulo" yenkqubo yokuvelisa efana nokusika okanye ukuwelda, oko kuthetha ukuba ayizukutshintsha kancinci imilo kwiminyaka yokusetyenziswa. Olu zinzo lwexesha elide luqinisekisa ukuba i-CMM elinganisiweyo namhlanje iya kuhlala ichanekile iminyaka ezayo, ibonelela ngesiseko esihambelanayo semveliso yemizi-mveliso.
Ukusebenza okuphezulu kweThermal
Ubushushu mhlawumbi lolona tshintsho lukhulu kwilebhu ye-metrology. Nangona iilebhu ezininzi zilawulwa yimozulu, ubushushu obuvela kwiimoto, kwi-elektroniki, kwanakumqhubi womntu bunokudala iimozulu ezincinci ezichaphazela ukuchaneka komatshini. I-granite emnyama yaziwa ngomlinganiselo wayo ophantsi wokwanda kobushushu. Ngaphezu koko, ubunzima bayo obuphezulu bobushushu buthetha ukuba isabela kancinci kakhulu kutshintsho lobushushu.
Nangona icandelo lentsimbi linokusabela ngoko nangoko kumoya ofudumeleyo, igranite isebenza njenge "sink" yobushushu, ifunxa ubushushu ngaphandle kotshintsho olukhawulezileyo. Eli xesha lokuphendula kancinci livumela isoftware yomatshini ukuba ihlawule ngokulula utshintsho lokusingqongileyo, nto leyo ekhokelela kwidatha ethembekileyo ngakumbi kwiimeko zomgangatho wevenkile. Kubavelisi behlabathi abasebenza kwiindawo ezahlukeneyo zemozulu, le inertia yobushushu yinzuzo ebalulekileyo ekhusela ukuthembeka kwenkqubo yabo yokulawula umgangatho.
Ukudambisa ukungcangcazela kunye nobunzima
Ukuchaneka akupheleli nje ekuhlaleni ungashukumi; kukwamalunga nokuxhathisa intshukumo. Ii-CMM zihlala zisebenza kwiindawo apho oomatshini abanzima, ii-forklift, okanye iinkqubo ze-HVAC zenza ukungcangcazela komgangatho okungaguqukiyo. Ezi ngcangcazela zinokuhamba kwisakhelo somatshini kwaye zibonakale "njengengxolo" kwidatha yokulinganisa, nto leyo ekhokelela ekungamkeleki okungachanekanga okanye ukufundwa okungahambelaniyo.
Uxinano olukhulu lwegranite emnyama (ngesiqhelo malunga ne-3100 kg/m³) lubonelela ngobunzima obufunekayo bokumisa umatshini. Okubaluleke ngakumbi, igranite ineempawu ezintle zokudambisa ngaphakathi. Ngokwendalo ichitha amandla e-kinetic ngokukhawuleza kakhulu kunentsimbi ephosiweyo okanye i-aluminium. Xa iprobe ye-CMM ihamba ngesantya esiphezulu, izinto zegranite zinceda ukuginya i-inertia ephumayo, okuvumela umatshini ukuba uhlale ngokukhawuleza kwaye uthathe imilinganiselo ngokukhawuleza ngaphandle kokunciphisa ukuchaneka.
Ukumelana nokunxitywa kunye nokugcinwa
I-CMM lutyalo-mali olukhulu, kwaye ubude bayo buxhomekeke ngokuthe ngqo ekuqineni komphezulu wayo. Iindlela ezikhokelayo ze-CMM—indawo apho iibheringi zomoya zidada khona—kufuneka zihlale zithe tyaba kwaye zigudile. I-granite emnyama iqinile kakhulu, ihlala iphezulu kunezinye iintsimbi kwisikali se-Mohs. Obu bunzima buyenza imelane kakhulu nemikrwelo kunye nokukrazulwa.
Ngaphezu koko, i-black granite ayisebenzisi magnethi kwaye ayisebenzisi umbane. Ayitsali uthuli lwesinyithi okanye iziqwenga ezinokuphazamisana neeprobe ze-elektroniki ezibuthathaka okanye zikrwele iindlela zokuqondisa. Ngenxa yokuba ayinayo ikhemikhali, ayigqwali okanye ibole xa ivezwe kumswakama okanye kwiioyile ezivela ezandleni zomqhubi. Olu hlobo "lokungalungiswa kakhulu" luluncedo olukhulu ekusebenzeni, olunciphisa ixesha lokungasebenzi elifunekayo lokucoca nokulungisa umphezulu.
Ukufezekisa ukuleyipha okuchanekileyo
Ukwenziwa kwezinto zegranite emnyama kubandakanya inkqubo eyaziwa ngokuba yi-lapping, apho ilitye ligaywa kusetyenziswa izinto ezicolekileyo ngakumbi. Ngenxa yesakhiwo segranite esifanayo, iingcali zinokufikelela ekunyamezeleni ukuthamba okungenakwenzeka ukuba kuphindaphindwe ngeentsimbi. Isiseko se-CMM segranite emnyama sinokuthambathiswa sibe sithambathi esilinganiswa ngamabhendi okukhanya, okubonelela ngendawo ephantse igqibelele ukuze iibheringi zomoya zityibilike phezu kwaso.
Olu bushelelezi lubalulekile kwintshukumo "engenazingxabano" efunekayo kwii-CMM zanamhlanje ezikhawulezayo. Iibheringi zomoya zifuna umsantsa ohambelanayo wee-microns ezimbalwa kuphela; ukuba umphezulu we-granite wawuneziphazamiso ezincinci, ibheringi yayinokuqhekeka, nto leyo ekhokelela ekulungisweni okubizayo. Amandla e-granite emnyama okugcina ezi ziphithiphithi zigqithisileyo yimbangela yokuba ihlale ingukumkani ongenakuphikiswa wezixhobo ze-metrology.
Isiphelo: Umgangatho weHlabathi wokuChaneka
Njengoko imveliso isiya kwimveliso "engenazo iziphene", indima yeCMM iba yeyona ibaluleke ngakumbi. Ngokukhetha izinto zegranite emnyama, abavelisi batyala imali kwinqanaba eliphezulu lokuzinza, ukuqina, kunye nokuchaneka. Ukususela ekuthomalaliseni ukungcangcazela kwendalo ukuya ekuchaseni ukushukuma kobushushu, iingenelo zegranite emnyama zezona zivumela i-metrology yanamhlanje ukuba ityhale imida yoko kunokulinganiswa.
Kwiinkampani ezithengisa izinto kwamanye amazwe kwihlabathi liphela, ukubonelela iiCMM ngeziseko zegranite emnyama luphawu lomgangatho oluqatshelwa kwihlabathi liphela. Luphawu oluthetha ulwimi oluchanekileyo oluqhelekileyo, oluqinisekisa ukuba nokuba inxalenye ilinganiswa phi na emhlabeni, inyaniso ihlala iqinile njengelitye emi kulo.
