Vadyidzani vatatu ava vakapa ruzivo rwavo rwakasiyana-siyana rwekugadzira nekugadzirisa uye mavambo avo ekupedzisira kuti vakawana SPR Machine muna 2002. Iyi Hamilton, Ohio machine shop yakakura kubva pa 2,500 square feet kusvika 78,000 square feet, ine 14 mill akavhara pasi, pamwe ne lathes, welding nemidziyo yekuongorora, zvese zvakagadzirirwa kunyanya kushandira nzvimbo yemhepo uye maindasitiri ekurapa.mhando blanks kubva 60 inches kusvika 0.0005 inches.
Zvese izvi tarenda, ruzivo uye simba rebhizimusi rinoita SPR Machine chitoro chakavhurika chinombundira matambudziko matsva ekukura nechido.SPR yakasvetukira pamukana apo imwe yematambudziko ekushandura simbi kuita chikamu chendarira zvinhu yakasimuka uye yaida kuona kuti ingani nguva yekutenderera SPR yaigona kuchengetedza nekumhanyisa machining.
Izvi zvakazoita kuti musangano kune zvishandiso zvitsva, intuition, zvidzidzo zvevashandi uye ruremekedzo rutsva rwekuita zvakasiyana-siyana uye machinability yendarira.
Mukana wakauya apo muvambi wemubatanidzwa Scott Pater aive ari kunze kwemugwagwa uye RC anofarira mota, uye akabatanidza izvo zvishuwo neshamwari kuti dzimhanyire kunze-nzira RC mota.
Shamwari iyi payakagadzira vhezheni yakagadziridzwa yechikamu cheRC ndokutanga kuchipa muzvitoro zvekuzvivaraidza, Pater akamuratidza kuti SPR yaizove mutengesi ari nani pane mutengesi weChinese, kunyanya sezvo kuodha mhiri kwemakungwa kunoreva mwedzi yekumirira kugamuchira zvikamu.
Iyo yekutanga dhizaini yakashandisa 12L14 simbi, iyo yakaora uye yakawedzera, zvichiita kuti zviome kubvisa mushure mekushandisa.
Aluminium inogadzirisa dambudziko rekuora, asi inoshaya simba uye uremu hwekupa kugadzikana mumotokari diki ine nzvimbo yakaderera yegiravhiti.
Brass inosanganisa zvese nechitarisiko chinoyevedza chinoita kuti chidimbu chifadze vatengi uye inosimbisa SPR's yakatarisana nemhando.Zvakare, ndarira haiburitse marara akareba uye anonamira eshiri yeSPR semamwe masimbi, kunyanya munzvimbo dzinenge 4 ″ dzakacherwa refu.
"Brass inoshanda nekukurumidza, machipisi anobuda zvakanaka, uye vatengi vanofarira zvavanoona muchikamu chapera," akadaro Pater.
Pabasa iri, Pater akaisa mari mukambani yechipiri CNC lathe, nomwe-axis Swiss-style Ganesh Cyclone GEN TURN 32-CS ine maviri 6,000 RPM spindles, 27 maturusi, mitsara dhairekitori, uye gumi nemaviri-foot static bar feed press..
“Pakutanga takagadzira chikamu ichi chekongiri palatheti yeSL10.Taifanira kuchina divi rimwe chete, totora chikamu chacho toripiringisha kuti tipedze kumashure,” anodaro Pete."PaGanesha, chikamu chinopedzwa zvachose pakarepo painobuda mumushini."Nemuchina mutsva wavainawo, SPR yaida kutsvaga vanhu chaivo kuti vanzwisise zviri nani curve yekudzidza.
Operator David Burton, aimbove wedhipatimendi rekubvisa mari reSPR, akatambira dambudziko iri.Mwedzi mishoma gare gare, akadzidza block coding uye G-code yemuchina-axis maviri uye akanyora kodhi kodhi yechikamu.
Kudyidzana kweSPR neCincinnati-based machinability consulting femu yeTechSolve yakapa chitoro mukana wakasarudzika wekugadzirisa chikamu ichi mukubatana neCopper Development Association (CDA), inomiririra vagadziri vemhangura, bhuronzi uye ndarira nevashandisi..
Mukuchinjana neTechSolve inotungamira maparamendi ekugadzira kuSPR, iyo shopu pasi inogashira yekupedzisira yakagadziridzwa paramita kubva kumuchina uye nyanzvi dzezvinhu.
Pamusoro pekutendeuka, chikamu ichi pakutanga chaida kugaya bhora, kuchera makomba akawanda akadzika, nekuboora maburi emukati mukati medhayamita.
MaGanesh akati wandei nemasanhu akachengetedza nguva yekugadzira, asi hurongwa hwekutanga hwekugadzira hwaBurton hwakakonzera kutenderera kwemaminetsi matanhatu masekonzi gumi nematanhatu, zvichireva kuti mayunitsi makumi manomwe nematanhatu akagadzirwa ega ega 8 maawa.
Mushure mekunge SPR yaita kurudziro yeTechSolve, nguva yekutenderera yakaderedzwa kusvika maminetsi maviri masekonzi makumi maviri uye huwandu hwezvikamu pakuchinja kwakawedzera kusvika pa191.
Kuti uwane iyi optimization, TechSolve yakaratidza nzvimbo dzinoverengeka uko SPR inogona kuderedza nguva dzekutenderera.
SPR inogona kutsiva kugaya kwebhora nebroaching, kujoinha zvikamu uye kugadzira mitsetse mishanu panguva, izvo zvingangoita zvisingashande pakugadzira simbi isina tsvina kana simbi.
SPR inochengetedza yakatowanda nguva neakasimba carbide zviboorero zvekuboora, madyisa ane hutsinye uye kudzika nekudzokororwa kushoma uye kudzika kukuru kwekuchekwa kwekukorokoza.Kuenzanisa mutoro webasa pakati pezvirukwa zviviri zvinoreva kuti hapana anomirira kuti mumwe apedze basa, achiwedzera kubuda.
Pakupedzisira, iyo yakakwana machinability yendarira inoreva kuti maitiro anogona kuitwa nekumhanya kwakanyanya uye anodyisa netsanangudzo.
SPR inobvumira TechSolve kugadzirisa maitiro kuitira kuti shopu ione zvikomborero zvekushandisa ndarira mune zvimwe zvikamu zvekugadzira.
Hurongwa hwekutanga hwekugadzira hwaBurton hwakapa pekutangira, uye SPR's own optimizations yakaderedza kutenderera nguva zvakatowedzera.
Asi kukwanisa kuona hurongwa hwese kubva pakuongorora kusvika pakugadzirisa kugadzirwa mukana wakasiyana, sekushandiswa kwendarira pachayo.
Sezvo SPR yakaziva, ndarira inopa akawanda mabhenefiti, mamwe acho anomira pachena muchirongwa ichi.
Nekumhanyisa-kumhanyisa machining endarira, unogona kukurumidza kuchera makomba akadzika, kuchengetedza kurongeka uye kuwedzera hupenyu hwechishandiso panguva dzekuchinja kwenguva refu.
Sezvo ndarira ichida kushoma machining simba pane simbi, kupfeka kwemuchina kunodzikiswa zvakare uye kumhanya kwepamusoro kunogadzira kushoma kutsauka.Nekusvika 90% zvimedu zvendarira, SPR inokwanisa kuita pundutso kubva kumakina machipisi kuburikidza nehurongwa hwekudzokorodza.
Sekutaura kunoita Pate, "Brass inopa mibairo mikuru yekubudirira.Midziyo yako ndiyo yako yekumisa chinhu kunze kwekunge uine maturusi epamberi anogona kunyatso mhanyisa machining.Nekuvandudza michina yako, unogona kuvhura mukana chaiwo wendarira. "
SPR's Lathe Division inoshandisa ndarira yakawanda kupfuura chero chinhu chipi zvacho, kunyangwe chitoro chose chinogadzirisawo aluminium, simbi isina tsvina uye zvinhu zvakakosha zvinosanganisira mapurasitiki sePEEK.Kufanana nebasa rakawanda iro SPR inogadzira, mainjiniya uye inogadzira, zvikamu zvaro zvendarira zvinoita basa rakakosha mukutsvagisa nzvimbo, telemetry yemauto, zviridzwa zvekurapa uye mamwe maapplication anowanzo batanidza zvibvumirano zvekusaburitsa pachena nemazita evatengi, mazhinji acho ari vatengi.SPR zvabuda hazvibvumidzwe.zita.Rudzi rwebasa iro musangano rinoita zvinoreva kuti kushivirira kunopatsanura SPR kufambiswa kwebasa muinenge hafu muchikamu chezviuru zvitatu uye zvimwe muzvikamu zvitatu zvegumi.
Adam Estel, Director weCDA weMabhawa nemaBhawa, akati: “Kushandisa brass mukugadzira michina inomhanya zvakanyanya kunobatsira magiyo kururamisa kudyara mumidziyo mitsva sezvo kuchiwedzera mari nekubudirira uye kuvhura bhizinesi idzva.Isu tinofara zvikuru nezvakaitwa neSPR, izvo zvinofanirwa kukurudzira zvimwe zvitoro kuti zviite hutsinye nendarira. "
George Adinamis, Senior Injiniya kuTechSolve, akarumbidza SPR nekuvhurika, achiti, "Kurumbidza kukuru kuti SPR inogovera ruzivo uye kuvimba nesu, uye maitiro ese ndeekubatana kwakazara."
Muchokwadi, vamwe vatengi veSPR vanovimba naScott Pater kuti vabatsirwe nechikamu chekuvandudza, chikamu dhizaini, uye zano rezvinhu, saka SPR inogona kushandisa ndarira pane mamwe mapurojekiti uye kuona vatengi vavo vachitevera zano rake.
Pamusoro pekugadzira nekugadzira zvikamu zvevamwe vatengi, akazove mutengesi pachake, achigadzira guva rinobvumira mana-axis lathes uye zvigayo kumichina kutenderera uye flat workpieces uye castings.
“Magadzirirwo edu anotipa kuita kwepamusoro uye akareruka muhuremu, asi akasimba zvekuti munhu anogona kuiisa pamushini,” akadaro Pater.
Chiitiko cheSPR chakaomarara chinosimudzira hunyanzvi hwepurojekiti, kubatana, uye nzira yekubudirira, nendarira ichiita basa rinowedzera kukosha mukufambiswa kwebasa rake.
Iine chiitiko ichi chakasanganiswa chinosimbisa mabhenefiti ekushanda nendarira, SPR Machine inotarisa kune zvimwe zvikamu zvekushandura mikana yekuvandudza kushanda nesimba uye pundutso.
