Munyika ine hungwaru hwekugadzira zvinhu nemazvo, uko kushivirira kunoyerwa muma microns uye kudzokorora hakugone kutaurirana, chinhu chimwe chete chepakutanga chinowanzo onekwa—kusvika chakundikana. Chinhu ichocho ndicho chinhu chinotangira kuyerwa kwese. Ungave uchichidana kuti ndiro yemainjiniya, granite master surface, kana kuti datum huru yechitoro chako, basa rayo haritsiviwi. Asi nzvimbo dzakawanda dzinofunga kuti kana dzaiswa, nzvimbo iyi inoramba yakavimbika nekusingaperi. Chokwadi ndechekuti pasina kutarisirwa kwakakodzera uye nguva nenguva.kugadzirisa tafura yegranite, kunyange chiyeuchidzo chepamusoro-soro chinogona kutsauka—zvichikanganisa chinyararire chiyero chose chinotorwa pachiri.
Nyaya iyi inonyanya kukosha kana ikabatanidzwa nemichina yekuyera yemazuva ano yepamusoro-soro—mageji ekukwirira, zviratidzo zvekudhirowa, macomparators ekuona, uye michina yekuyera yekubatanidza (CMMs). Zvishandiso izvi zvinongofanana nepamusoro pazvinongoreva. Kukombama kwe micron-level muplate yeinjiniya isina kugadzikwa kunogona kupinda mumapasi enhema, zvimedu zvisingatarisirwi, kana zvakatoipa—kukundikana kwemunda muzvikamu zvakakosha zvebasa. Saka vagadziri vanotungamira vanoita sei kuti hwaro hwavo hwemetrology hurambe hwakarurama? Uye chii chaunofanira kuziva usati wasarudza kana kuchengetedza mwero wako wekutarisa?
Ngatitangei nemashoko. MuNorth America, izwi rekuti mainjiniya ndiro rinowanzoshandiswa kutsanangura ndiro yepamusoro-soro—yakagadzirwa nesimbi yakakandwa kare, asi kwemakore anopfuura makumi mashanu, yakagadzirwa zvakanyanya kubva kugranite nhema munzvimbo dzehunyanzvi. MuEurope nemisika yakaenderana neISO, inowanzonzi "plate yepamusoro" kana "plate yekutarisa," asi basa racho rinoramba rakafanana: kupa ndege yakagadzikana, yakati sandara iyo zviyero zvese zvemutsetse nemakona zvinosimbiswa. Kunyange zvazvo maplate esimbi akakandwa achiripo muzvigadzirwa zvekare, nzvimbo dzemazuva ano dzakanyatsojeka dzakachinja kuita granite nekuda kwekugadzikana kwayo kwakanyanya kwekupisa, kuramba ngura, uye kusimba kwenguva refu.
Zvakanakira granite hazvisi zvekufungidzira chete. Nekuwedzera kwekushisa kwesimbi kwakaenzana nechikamu chimwe muzvitatu, plate yegranite inogadzira mainjiniya ine mhando yepamusoro inosangana nekukanganisika kushoma panguva yekuchinja-chinja kwekushisa kwemu workshop. Haina ngura, haidi mafuta, uye chimiro chayo chakasimba che crystalline chinoderedza kudedera—kwakakosha pakushandisa sensitive.michina yekuyera michinasezviratidzo zve dial test indicators kana kuti electronic height masters. Uyezve, kusiyana nesimbi yakakandwa, iyo inogona kukonzera kushushikana kwemukati kubva mukugadzirwa kana kukanganiswa, granite inoshanduka uye inopenya, zvichireva kuti inoita zvakafanana munzira dzese dziri pasi pemutoro.
Asi heino dambudziko: kunyangwe granite haifi. Nekufamba kwenguva, kushandiswa kakawanda—kunyanya nezvishandiso zvakaoma, magage blocks, kana zvinhu zvinogumbura—kunogona kusakadza nzvimbo dziri munzvimbo yacho. Zvinhu zvinorema zvinoiswa kunze kwepakati zvinogona kukonzera kudzika zvishoma kana nzvimbo dzekutsigira dzisina kugadziriswa. Zvinosvibisa zvakatipoteredza zvakaita se coolant residue kana metal chips zvinogona kupinda muma micro-pores, zvichikanganisa kupfava. Uye nepo granite isinga "konzere" sesimbi, inogona kuunganidza microscopic deviations inowira kunze kwebhandi rako rekutsungirira rinodiwa. Apa ndipo panoshandiswa granite table calibration kwete sarudzo, asi yakakosha.
Kugadzirisa hakusi kungoshandisa chitupa cherabha chete. Kugadzirisa tafura yegranite chaiyo kunosanganisira kuyera nzvimbo yese uchishandisa interferometry, mazinga emagetsi, kana matekiniki e autocollimation, uchitevera zviyero zvakaita se ASME B89.3.7 kana ISO 8512-2. Mhedzisiro yacho i mepu yakadzama inoratidza kutsauka kubva pakakwirira kuenda kumupata muplate, pamwe chete nechirevo chekutevedzera giredhi rakati (semuenzaniso, Giredhi 00, 0, kana 1). Marabhoritari ane mukurumbira haangotauri kuti "yakadzika" - anokuratidza kuti inotsauka kupi uye kuti inotsauka zvakadii. Ruzivo urwu rwakakosha kumaindasitiri ane njodzi dzakadai seaerospace, kugadzira zvishandiso zvekurapa, kana semiconductor tooling, uko kutevedzera NIST kana zviyero zvenyika zvakaenzana kuri kudikanwa.
KuZHHIMG, takashanda nevatengi vaifunga kuti ndiro yavo yegranite ine makore gumi "yakanga ichiri yakanaka" nekuti yaitaridzika yakachena uye yakatsetseka. Mushure mekunge kusawirirana kweCMM kwakonzera kugadziriswa kwakazara ndipo pavakazowana kunyura kwema micron gumi nemaviri pedyo nekona imwe chete - kwakakwana kubvisa kuverenga kwegeji yekukwirira ne 0.0005 inches. Kugadzirisa kwacho kwaisava kutsiva; kwaive kudzokorora uye kugadzirisazve. Asi pasina kugadzirisa tafura yegranite nekukurumidza, kukanganisa ikoko kwaizoramba kuripo, kuchikanganisa data remhando yacho chinyararire.
Izvi zvinotisvitsa kumamiriro ezvinhu akafara ehupenyu hwemichina yekuyera michina. Zvishandiso zvakaita se sine bars, precision parallels, V-blocks, uye dial test stands zvese zvinoshandisa mainjiniya plate se zero-reference yavo. Kana reference iyoyo ikachinja, cheni yese yekuyera inokanganiswa. Funga nezvazvo sekuvaka imba pavhu rinoshanduka-madziro anogona kutaridzika akatwasuka, asi hwaro hwacho hwakakanganisika. Ndosaka ma lab akasimbiswa ne ISO/IEC 17025 achiraira nguva dzekugadzirisa dzezviyero zvese zvekutanga, kusanganisira mapurati epamusoro. Nzira yakanakisisa inoratidza kuyera kwegore negore mapurati eGiredhi 0 ari kushandiswa, uye maviri pagore kune nzvimbo dzisinganyanyi kuoma - asi ruzivo rwako rwengozi runofanira kutsanangura purogiramu yako.
Pakusarudza plate itsva yeinjiniya, tarisa kupfuura mutengo. Simbisa kwakabva granite (yakatsetseka, nhema, yakarerutswa kushushikana), simbisa giredhi rekuti yakatsetseka nekusimbisa chaiko—kwete zvirevo zvekushambadzira—uye iva nechokwadi chekuti mutengesi anopa gwara rakajeka pakutsigira, kubata, uye kugadzirisa. Plate ye48″ x 96″, semuenzaniso, inoda rutsigiro rwemapoinzi matatu kana akawanda panzvimbo dzakakodzera kudzivirira kutsauka. Kudonhedza chipanera pairi kungasaitsemura, asi kunogona kutsemura mupendero kana kugadzira nzvimbo yakakwirira yenzvimbo inokanganisa kukwenya kwegage block.
Uye yeuka: kugadzirisa zvinhu hakusi kungotevedzera mitemo chete—kune chivimbo. Kana muongorori akabvunza kuti, “Unovimbisa sei kuti nzvimbo yako yekuongorora inobvumirwa?” mhinduro yako inofanira kusanganisira mushumo wekugadzirisa tafura yegranite unoteverwa, une mamepu ekutsauka. Pasina izvozvo, sisitimu yako yese yekutarisira mhando haina chinosimbisa.
KuZHHIMG, tinotenda kuti kunyatsoita zvinhu nemazvo kunotanga kubva pakutanga—chaizvoizvo. Ndosaka tichingotsvaga kubva kumaworkshops anosanganisa hunyanzvi hwemazuva ano hwekugadzira machira nekuongorora kwemetrology. Mapuratifomu ese einjiniya atinopa anoongororwa pamatanho maviri: kutanga nemugadziri achishandisa nzira dzinoenderana neASME, uye timu yedu yemukati isati yatumirwa. Tinopa magwaro akazara, rutsigiro rwekugadzirisa, uye kurongazve kuti uve nechokwadi chekuti mari yako inopa makumi emakore ebasa rakavimbika.
Nekuti pakupedzisira, metrology haisi yezvishandiso—inyaya yechokwadi. Uye chokwadi chinoda nzvimbo yakagadzikana yekumira. Ungave uchigadzirisa imba ye turbine, uchisimbisa core ye mold, kana kuyera mafambiro ehurefu, michina yako yekuyera inofanirwa kuva nehwaro hwaunogona kuvimba nahwo. Usarega nzvimbo isina kugadziriswa ichiva chinhu chakavanzwa mu equation yako yemhando.
Saka zvibvunze kuti: puratifomu yako yeinjiniya yakapedzisira kugadzikiswa riini neunyanzvi? Kana usingakwanise kupindura izvozvo nechivimbo, inguva yekudzosa hwaro hwako kuti huenderane. KuZHHIMG, tiri pano kuti tikubatsire—kwete kungotengesa granite chete, asi kuchengetedza kunaka kwekuyerwa kwese kwaunoita.
