Kwihlabathi le-metrology kunye nokuhlolwa okuchanekileyo, i-Coordinate Measuring Machine (CMM) imi njengomlamli wokugqibela womgangatho. Nangona kunjalo, ukuchaneka kwe-CMM akuyonto nje ixhomekeke kwisoftware yayo okanye kwiisensa zayo; ngokusisiseko ilawulwa sisiseko esibonakalayo apho ezo sensa zihamba khona. Kangangamashumi eminyaka, iinjineli kunye neengcali zokuthenga ziye zajongana nengxoxo ephindaphindiweyo: ngaba isiseko somatshini kufuneka sakhiwe nge-precision granite okanye ngentsimbi yendabuko?
Ukukhetha izinto ezifanelekileyo sisigqibo esibalulekileyo esichaphazela ixesha elide lomatshini, indlela osabela ngayo kutshintsho lwendalo, kwaye ekugqibeleni, ukuthembeka kwedatha evelisayo. Zombini ezi zinto zisebenzele ishishini lokuvelisa iminyaka engaphezu kwekhulu, kodwa zibonelela ngeendlela ezahlukeneyo zoomatshini. Ukuqonda umahluko phakathi kwezi "ziintsimbi ezisindayo" zimbini kubalulekile kuyo nayiphi na indawo efuna ukuphucula isebe layo lokuhlola kwiimfuno zemveliso yanamhlanje.
Inzuzo yeJiyoloji yeGranite echanekileyo
I-granite iye yaba lukhetho oluphambili kwizakhiwo ze-CMM zanamhlanje eziphezulu, kwaye ngesizathu esihle. Ngokwembono ebonakalayo, i-granite emnyama yenye yezona zinto zizinzileyo ezifumaneka kwindalo. Amandla ayo aphambili akwi-coefficient yayo yokwanda kobushushu, ephantsi kakhulu kuneyeentsimbi ezininzi. Kwindawo apho ubushushu bungalawulwa ngokugqibeleleyo ukuya kuthi ga kwisiqingatha sedigri, isiseko sesinyithi siya kwanda size sinciphe, nto leyo ebangela ukuba i-geometry yokulinganisa ihambe. I-granite ihlala ingasebenzi kakuhle, iqinisekisa ukuba "i-zero point" ihlala kanye apho ifanele ukuba khona.
Ngaphaya kozinzo lobushushu, igranite ayidli mhlwa kwaye ayivumi iasidi. Kwiindawo ezininzi zoshishino, ukufuma okanye umphunga weekhemikhali unokukhokelela kwi-oxidation kwiindawo zesinyithi. Ngelixa isinyithi esityhidiweyo sifuna ukutshizwa rhoqo kunye nokugcinwa ukuze kuthintelwe ukugqwala, igranite ifuna kuphela ukusula okulula kunye nesicoci esikhethekileyo. Ngaphezu koko, igranite ayisebenzisi magnethi. Kwii-CMM ezisetyenziswa kwiindawo ze-elektroniki okanye ezinobuthathaka kwimagnethi, olu luphawu olubalulekileyo lokhuseleko kunye nokuchaneka.
Enye yezona mpawu zikhethekileyo zegranite kukuba "ayidubuli". Ukuba ipleyiti yomphezulu wegranite okanye isiseko somatshini sitshaywe ngengozi okanye siqhekekile, loo nto ayithi "ikhowa" okanye inyuse umqolo ujikeleze indawo entlithwe kuyo. Oku kuthetha ukuba ubunzulu bomphezulu buhlala bunjalo, bukhusela iibheringi zomoya kunye nokuchaneka kwebhulorho ehambayo.
Ilifa Lesinyithi Esixonxiweyo
Nangona i-granite ilawula imarike ye-CMM, i-cast iron isasoloko iyinto efunekayo kwihlabathi elibanzi lobunjineli obuchanekileyo kunye nokuveliswa kwemveliso enzima. I-grey cast iron esemgangathweni ophezulu okanye i-ductile iron yindlela efanelekileyo yeebhedi zezixhobo zoomatshini kunye namaqonga amakhulu emizi-mveliso. Isizathu sisekuqineni kwesakhiwo sayo kunye nokukwazi kwayo ukuphoswa kwiimo ezintsonkothileyo.
Amaqonga esinyithi anika umgangatho "wokuqina kwesakhiwo" ongenakulinganiswa negranite. Kwiinkqubo ezibandakanya izinto zokusebenza ezinzima okanye imithwalo enamandla, isinyithi esitshisiweyo asinakuqhekeka xa sixinezelekile kakhulu. Yingakho amaqonga esinyithi asetyenziswa rhoqo njengendawo yokuqala yokuhlanganisa nokuvavanya kwimveliso yeemoto neenqwelo moya. Iqonga lesinyithi esitshisiweyo elisemgangathweni ophezulu, elinongwe kakuhle kwaye likrwelwe ngokuchanekileyo, libonelela ngendawo yokubhekisa enokusingatha ubunzima bomsebenzi onzima ngelixa ligcina ubunzulu obumangalisayo.
Ngaphezu koko, isinyithi esityhidiweyo sinomlinganiselo ophezulu wokuguquguquka, nto leyo eyenza ukuba sibe sihle kakhulu kwizinto ezimele zimelane nokuphambuka phantsi kobunzima obukhulu. Kwimisebenzi yokuhlolwa okukhulu apho umsebenzi unobunzima beetoni ezininzi, iqonga lesinyithi esityhidiweyo lidla ngokubonelela ngesakhiwo esifunekayo sokuxhasa esinokuthi inkqubo esekelwe kwilitye kuphela ibe nzima ukusinyamezela ngaphandle kobunzima obukhulu.
Ukudambisa kunye nokungcangcazela: Idabi Elithuleyo
Kuyo nayiphi na indlela yokusebenzisa i-metrology, ukungcangcazela lutshaba. Kungenisa ingxolo kwidatha kwaye kunokubangela izinto ezingezizo kwiiprobe zokuchukumisa ezibuthathaka. I-granite igqwesile ekuthomalaliseni ukungcangcazela okuphezulu ngenxa yesakhiwo sayo sangaphakathi esixineneyo, esineembobo, nesingafaniyo. "Ifunxa" ngokufanelekileyo amandla omgangatho wevenkile, idala indawo ezolileyo yokusebenza kwebhulorho yokulinganisa.
Isinyithi esitshisiweyo sikwanomgangatho omhle wokudambisa—ungcono kakhulu kunesinyithi—kodwa sidla ngokuphendula ngendlela eyahlukileyo kwi-resonance ephantsi. Kwiisetingi ezininzi zokuvelisa eziphezulu, isisombululo esifanelekileyo asikokukhetha enye kunenye, kodwa kukuqonda apho nganye ifaneleka khona. Kwiintshukumo ezichanekileyo kakhulu, ezingaphantsi kwe-micron zebhulorho ye-CMM, ukudambisa i-granite kudla ngokukhethwa. Kwindawo enzima, engcangcazelayo yeziko loomatshini okanye umgca wokuhlanganisa, ukudambisa ubunzima kunye nokwangaphakathi kweqonga lesinyithi esitshisiweyo kuhlala kulukhetho oluphezulu.
Ukugcinwa, Ukuphila Ixesha Elide, kunye Nokusebenza Kakuhle Kweendleko
Ngokwembono yolondolozo, i-granite yeyona iphumeleleyo kwiisicelo ze-CMM. Ukuchasana kwayo nokuguguleka kunye neemeko zokusingqongileyo kuthetha ukuba isiseko se-granite sinokugcina sithe tyaba kangangeminyaka emininzi ngaphandle kokungenelela okuncinci. Nangona kunjalo, kubalulekile ukuqaphela ukuba amaqonga esinyithi anikezela ngenzuzo ekhethekileyo: anoku "lungiswa kwakhona" ngokukrwela ngesandla okanye ngokusila ngokulula kwezinye iimeko zoshishino ezinkulu.
Xa uvavanya iindleko, umntu kufuneka ajonge "Ixabiso lilonke lobunini." Isiseko segranite sinokuba nexabiso eliphezulu lokuqala lezinto okanye ubunzima bokuthunyelwa, kodwa ukungabikho kweemfuno zokuthintela umhlwa kunye nokungakhuseleki kwaso ekuwohlokeni kokusingqongileyo kudla ngokwenza ukuba sibe nexabiso eliphantsi kwiminyaka engama-20. Ngokwahlukileyo koko, kwiindawo zokuhlola ezinkulu kumgangatho okanye imisebenzi yokubeka ngesandla, amaqonga esinyithi anikezela ngokuqina okubonelela ngexabiso elingcono kwiindawo ezinabantu abaninzi apho ilitye linokuba sengozini yokonakala komphezulu ngenxa yezixhobo zentsimbi enzima.
Isiphelo: Ukwenza Ukhetho Oluchanekileyo KwiZiko Lakho
Ukukhetha phakathi kwegranite echanekileyo kunye nentsimbi ephosiweyo ekugqibeleni kuxhomekeke kwisicelo sakho esithile. Ukuba injongo yakho kukuhlola ngesantya esiphezulu, ngokuzenzekelayo kunye nokuchaneka kwe-sub-micron kwilabhoratri elawulwayo, ukuzinza kunye nokufuma kwesiseko segranite emnyama akunakunqotshwa. Yinto ebalulekileyo kwixesha elizayo kwi-metrology echanekileyo.
Nangona kunjalo, ihlabathi lemizi-mveliso lisaxhomekeke kakhulu kumandla kunye nokuguquguquka kwamaqonga esinyithi adityanisiweyo ukuze adityaniswe, abekwe ngendlela enzima, kunye neeprojekthi zobunjineli ezinkulu. Zombini ezi zinto zibalulekile kwimveliso yanamhlanje. Ngokuqonda iingenelo zobushushu zegranite kunye nokuqina kwesakhiwo sesinyithi esidityanisiweyo, iinjineli zingakha iinkqubo zokuhlola kunye nemveliso ezingachanekanga kuphela namhlanje kodwa eziya kuhlala zizinzile kwizizukulwana ezizayo. Nokuba ufaka i-CMM entsha okanye uphucula umgangatho wakho wokudibanisa, ukukhetha izinto zesiseko yeyona nyathelo libalulekileyo ekuqinisekiseni ukuthembeka komsebenzi wakho wobunjineli.
