Mu dziko la metrology ndi kuwunika kolondola kwambiri, Coordinate Measuring Machine (CMM) ndiye woweruza womaliza wa khalidwe. Komabe, kulondola kwa CMM sikungodalira mapulogalamu ake kapena masensa ake; kwenikweni kumayendetsedwa ndi maziko enieni omwe masensa amenewo amayendera. Kwa zaka zambiri, mainjiniya ndi akatswiri ogula zinthu akhala akukumana ndi mkangano wobwerezabwereza: kodi maziko a makinawo ayenera kupangidwa ndi granite yolondola kapena chitsulo chachikhalidwe?
Kusankha zinthu zoyenera ndi chisankho chanzeru chomwe chimakhudza moyo wautali wa makinawo, momwe amachitira zinthu pakusintha kwa chilengedwe, komanso kudalirika kwa deta yomwe imapanga. Zinthu zonsezi zakhala zikutumikira makampani opanga zinthu kwa zaka zoposa zana, komabe zimapereka machitidwe osiyanasiyana amakina. Kumvetsetsa kusiyana pakati pa "zolemera" ziwirizi ndikofunikira kwambiri pa malo aliwonse omwe akufuna kukonza dipatimenti yawo yowunikira kuti igwirizane ndi zofunikira zamakampani amakono.
Ubwino wa Granite Woyenera Kwambiri
Granite yakhala chisankho chachikulu pa nyumba zamakono zapamwamba za CMM, ndipo pachifukwa chabwino. Malinga ndi momwe zinthu zilili, granite wakuda ndi chimodzi mwa zinthu zokhazikika kwambiri zomwe zimapezeka m'chilengedwe. Mphamvu yake yayikulu ili mu kuchuluka kwake kwa kutentha, komwe kumakhala kotsika kwambiri kuposa kwa zitsulo zambiri. Mu malo omwe kutentha sikuyendetsedwa bwino mpaka pang'ono, maziko achitsulo amakula ndikuchepa, zomwe zimapangitsa kuti mawonekedwe a muyeso asunthike. Granite imakhalabe yopanda kanthu, kuonetsetsa kuti "zero point" ikukhalabe komwe ikuyenera kukhala.
Kupatula kukhazikika kwa kutentha, granite mwachibadwa imakhala yolimba ndi dzimbiri komanso yolimba ndi asidi. M'malo ambiri amafakitale, chinyezi kapena nthunzi ya mankhwala ingayambitse kukhuthala kwa chitsulo pamwamba. Ngakhale chitsulo chopangidwa chimafuna mafuta nthawi zonse ndi kukonzedwa kuti chipewe dzimbiri, granite imangofunika kupukuta ndi chotsukira chapadera. Kuphatikiza apo, granite siigwiritsa ntchito maginito. Kwa ma CMM omwe amagwiritsidwa ntchito m'malo amagetsi kapena omwe amakhudzidwa ndi maginito, iyi ndi njira yofunika kwambiri yotetezera komanso kulondola.
Chimodzi mwa zinthu zapadera za granite ndi khalidwe lake "losaphulika". Ngati mbale ya granite pamwamba kapena maziko a makina agundidwa mwangozi kapena kusweka, zinthuzo sizimayika "bowa" kapena kukankhira mmwamba phiri mozungulira malo omwe agundidwa. Izi zikutanthauza kuti kusalala konse kwa pamwamba pake kumakhalabe bwino, kuteteza maberiyani a mpweya ndi kulondola kwa mlatho woyenda.
Cholowa cha Chitsulo Chopangidwa ndi Makina
Ngakhale granite ikulamulira msika wa CMM, chitsulo chopangidwa ndi miyala chikadali chinthu chofunikira kwambiri padziko lonse lapansi pakupanga zinthu zolondola komanso zolemera. Chitsulo cha imvi chapamwamba kwambiri kapena chitsulo chopangidwa ndi miyala yamtengo wapatali ndiye muyezo wagolide wa mabedi a zida zamakina ndi nsanja zazikulu zamafakitale. Chifukwa chake chili mu kulimba kwake ndi kuthekera kwake kupangidwa m'mawonekedwe ovuta.
Mapulatifomu achitsulo chopangidwa ndi miyala amapereka mulingo wa "kulimba kwa kapangidwe" komwe granite sangagwirizane nako. Pakugwiritsa ntchito zida zolemera kapena katundu wolemera kwambiri, chitsulo chopangidwa ndi miyala sichingasweke mosavuta pamene chikukakamizidwa kwambiri. Ichi ndichifukwa chake nsanja zachitsulo chopangidwa ndi miyala zimagwiritsidwa ntchito nthawi zambiri ngati malo oyambira osonkhanitsira ndi kuyesa magalimoto ndi ndege. Nsanja yachitsulo chopangidwa ndi miyala yamtengo wapatali, yokongoletsedwa bwino komanso yokonzedwa bwino, imapereka malo ofunikira omwe angagwiritsidwe ntchito bwino pantchito zamafakitale komanso kusunga malo osalala bwino.
Kuphatikiza apo, chitsulo chopangidwa ndi miyala chili ndi mphamvu yolimba kwambiri, zomwe zimapangitsa kuti chikhale chabwino kwambiri pazinthu zomwe ziyenera kupirira kupatuka pamene zikulemera kwambiri. Pa ntchito zazikulu zowunikira pomwe chogwirira ntchitocho chimalemera matani angapo, nsanja yachitsulo chopangidwa ndi miyala nthawi zambiri imapereka chithandizo chofunikira chomwe dongosolo lopangidwa ndi miyala yokha lingavutike kulikwaniritsa popanda kulemera kwakukulu.
Kufooka ndi Kugwedezeka: Nkhondo Yopanda Kanthu
Mu ntchito iliyonse ya metrology, kugwedezeka ndi mdani. Kumayambitsa phokoso mu deta ndipo kungayambitse zoyambitsa zabodza mu ma probe okhudzidwa. Granite imachita bwino kwambiri pochepetsa kugwedezeka kwa ma frequency chifukwa cha kapangidwe kake kamkati kokhuthala, kokhala ndi mabowo, komanso kosagwirizana. "Imatenga" bwino mphamvu ya pansi pa shopu, ndikupanga malo chete kuti mlatho woyezera ugwire ntchito.
Chitsulo chopangidwa ndi chitsulo chilinso ndi makhalidwe abwino oletsa kuzizira—bwino kwambiri kuposa chitsulo—koma chimakonda kuyankha mosiyana ndi kusinthasintha kwa ma frequency otsika. M'makonzedwe ambiri opanga apamwamba, yankho labwino si kusankha chimodzi kuposa china, koma kumvetsetsa komwe chilichonse chikugwirizana. Pa kayendedwe kolondola kwambiri, ka sub-micron ka mlatho wa CMM, kuzizira kwa granite nthawi zambiri kumakhala koyenera. Pamalo olemera komanso ogwedezeka a malo opangira makina kapena mzere wolumikizira, kuzizira kwa unyinji ndi mkati mwa nsanja yachitsulo chopangidwa ndi chitsulo nthawi zambiri kumakhala chisankho chabwino kwambiri.
Kusamalira, Kutalika kwa Nthawi, ndi Kugwiritsa Ntchito Ndalama Mwanzeru
Poganizira za kukonza, granite ndiye wopambana bwino pa ntchito za CMM. Kukana kwake kuwonongeka ndi zinthu zachilengedwe kumatanthauza kuti maziko a granite amatha kukhalabe osalala kwa zaka zambiri popanda kulowererapo kwambiri. Komabe, ndikofunikira kudziwa kuti nsanja zachitsulo zotayidwa zimapereka mwayi wapadera: zimatha "kukonzedwanso" mwa kukanda ndi manja kapena kupukuta mosavuta m'mafakitale ena akuluakulu.
Poyesa mtengo, munthu ayenera kuyang'ana pa "Mtengo Wonse wa Umwini." Maziko a granite akhoza kukhala ndi mtengo wapamwamba woyambira wa zinthu kapena kulemera kwa kutumiza, koma kusowa kwa zofunikira zopewera dzimbiri komanso chitetezo chake ku kuwonongeka kwa chilengedwe nthawi zambiri zimapangitsa kuti ikhale yotsika mtengo kwambiri pazaka 20. Mosiyana ndi zimenezi, pamadera akuluakulu owunikira pansi kapena ntchito zokonza pamanja, nsanja zachitsulo zotayidwa zimapereka kulimba komwe kumapereka phindu labwino m'malo omwe anthu ambiri amadutsamo komwe miyala ingawonongeke pamwamba ndi zitsulo zolemera.
Pomaliza: Kupanga Chisankho Chabwino pa Malo Anu
Kusankha pakati pa granite yolondola ndi chitsulo chopangidwa ndi chitsulo chopangidwa ndi chitsulo kumadalira momwe mungayigwiritsire ntchito. Ngati cholinga chanu ndi kuyang'ana mwachangu komanso modzidzimutsa pogwiritsa ntchito njira yolondola ya sub-micron mu labotale yolamulidwa, kukhazikika ndi kunyowa kwa maziko a granite wakuda sikungatheke. Ndi mfundo zamtsogolo za metrology yolondola.
Komabe, dziko la mafakitale limadalirabe kwambiri mphamvu ndi kusinthasintha kwa nsanja zachitsulo chopangidwa kuti zigwirizane, kuyika zinthu zolemera, komanso mapulojekiti akuluakulu aukadaulo. Zipangizo zonsezi ndi zofunika kwambiri popanga zinthu zamakono. Pomvetsetsa ubwino wa kutentha kwa granite komanso kulimba kwa kapangidwe ka chitsulo chopangidwa, mainjiniya amatha kupanga njira zowunikira ndi kupanga zomwe sizolondola masiku ano komanso zidzakhalabe zokhazikika kwa mibadwo ikubwerayi. Kaya mukuyika CMM yatsopano kapena kukweza pansi panu, kusankha maziko ndiye gawo lofunika kwambiri pakuwonetsetsa kuti ntchito yanu yaukadaulo ndi yolondola.
