Iwe hausi kubata kushivirira; uri kubata nzira. Isu tinoshandisa statistical process control pane dzakakosha zviyero, asi kunyangwe izvo zvinoda kutonga. Unomira rini uye uchigadzirisa? Kudzingirira iyo yekupedzisira micron pane yega yega inogona kupeta mutengo. Hunyanzvi chaihwo kuziva kuti ndezvipi zvibvumirano zvinoshanda uye izvo zvinongonyorwa-kunamirwa kubva kudhirowa yekare.
Kupedzisa kwepamusoro ndeimwe imwe. Ra 0.4μm inotaridzika zvakanaka pabepa. Kuzviwana nguva dzose pane yemukati contour mu cobalt-based alloy imhuka yakasiyana. Zvinowanzoreva kudya kunononoka, nzira dzematurusi (kukwira milling vs. zvakajairwa zvinova zvakakosha), uye dzimwe nguva chishandiso chakaparadzana chekupedzisa chisina kupfeka. Mutyairi wemutengo haisi iyo nguva yekugadzira wega; ndiko kushandiswa kwemidziyo uye kuwedzera kwekuongorora pamusoro.
Ini ndinorangarira batch yemitumbi yevharuvhu yeQSY uko yekuisa chisimbiso kupedzisa kwaive kwakakosha. Kudhindwa kwacho kwaida Ra 0.8. Isu takairova, asi panguva yekumanikidza bvunzo prototype, yakadonha. Nyaya yanga isiri yeavhareji roughness (Ra) asi chimiro-takanga tiine madiki e periodic mamaki kubva kune isina kukwana zvishoma. Iyo Ra mita yakaverenga zvakanaka, asi basa rakakundikana. Isu takachinjira kune wiper yekupinza uye imwe nzira yeturusi inopindirana. Iyo Ra nhamba haina kumbochinja, asi chimiro chepamusoro chakadaro, uye chisimbiso chakashanda. Iyo spec sheet haiwanzo taura nyaya yese.
Iyo Tooling & Setup Dhanzi
Muchina wako wakangonaka sekushandisa kwako uye munhu wako wekuseta. Zvepamusoro-soro CNC chaiyo machining zvikamu, tinoshandisa zvigadziriso zvakatsaurirwa, kazhinji hydraulic kana pneumatic. Asi kune yakaderera-vhoriyamu, yakakwira-musanganiswa basa, izvo zvakawanda zvatinoita, ndezve modular fixturing. Chinangwa ndechekuita kuti chikamu chacho chive chakasimba sezvinobvira nemaseti mashoma. Pese paunosungazve, unounza kukanganisa.
Muripo wekupfekedzwa kwemidziyo unowanzo itwa otomatiki izvozvi, asi kuziva nguva yekuripa ibhuku. Iwe unokudziridza pfungwa pazviri-inzwi rekucheka shanduko, machipisi anotaridzika akasiyana (ruvara, chimiro). Semuenzaniso, kugadzira yavo yakakosha nickel-based alloys, machipisi anofanirwa kubva neimwe nzira-inoenderera uye ine ruvara rwemashanga. Kana vakatanga kushanduka bhuruu uye kupfupika, chishandiso chiri kupera uye kushanda kuomesa zvinhu. Kana iwe ukamirira kutarisisa kwemuchina kuridza alarm, unogona kunge watoparadza kutendeseka kwechikamu.
Kutonhodza hakusi kwekutonhodza chete. Mukuchera kwakadzika-gomba kwezvikamu izvi, ndezvekubvisa chip. Taive nebasa rekuchera maburi 8mm, kudzika 120mm, musimbi 4140. Standard kuburikidza-turusi inotonhorera yakanga isina kukwana; machipisi akarongedza achibva arova chibhorani. Isu takachinjira kune yakakwira-pressure inotonhorera system (inopfuura 1000 psi) uye yakatsaurirwa pecking kutenderera. Dambudziko rakagadziriswa, asi raida kushandura pombi dzemuchina uye kurongazve. Aya ndiwo mashoko asina kunaka, anonyura nguva.
Kuongorora: The Final Reality Check
Chirevo cheCMM ndiye mutongi wekupedzisira. Asi haugone CMM chikamu chose. Kuongorora kwekutanga-chinyorwa kunopedza. Pamafambisirwo ekugadzira, iwe unoona zvakakosha-kune-basa zviyero uye pamwe 3-5 kiyi nzira yekudzora zviyero. Iwe unotarisa izvo pane frequency-yekutanga / yekupedzisira chidimbu, kana yega chidimbu chechigumi. Zvimwe zvacho? Unovimba maitiro ako.
Asi kuvimba kunovakwa pane data. Isu tinonyora zvese: hupenyu hwematurusi, zvigadziriso zvekugadzirisa, batch yezvinhu, kunyangwe tembiricha yakadzika pauriri hwechitoro kana riri basa rekushivirira rakasimba. Nokufamba kwenguva, unoona maitiro. Iwe unodzidza kuti batch nyowani yealuminium 6061 kubva kune mumwe mupi wemuchina zvakasiyana pane kubva kune imwe. Iwe unogadzirisa mafidhi ako uye nekumhanyisa zvinoenderana usati watombogadzira yekutanga kucheka.
Kune dzakaomarara dzakakandwa-kune-muchina zvikamu sezviya zvinogadzirwa neQSY, kuongorora kunowanzo sanganisira kutarisa machining maficha kudzoka kune asina kuisirwa madhamu ekukanda. Izvi zvinokuudza kana kukanda kwaive kwakanzwika kutanga. Takamboona kuti nhevedzano yemabhoti maburi aive kunze kwechinzvimbo kwete nekuda kwekugadzira kwedu, asi nekuti musimboti wekukanda wanga wachinja zvishoma. Kuve neiyo yakabatanidzwa kugona kuongorora zvese kukanda uye machining pasi pedenga rimwe, sezvavanoita, inomhanyisa kuongororwa kwemudzi-chikonzero zvakanyanya. Inoshandura mutambo wekupomera kuita chikamu chekugadzirisa matambudziko.
The Human Factor & The Bottom Line
Pakupera kwezuva, CNC chaiyo machining zvikamu imhizha inotsigirwa nehunyanzvi. Iyo programmer inofanirwa kufunga senge machinist achamhanyisa basa. Iyo machinist inofanirwa kunzwisisa chinangwa chemugadziri. Pane nguva dzose mhinduro inotenderera. Nzira yekushandisa yakakwana mukuenzanisa inogona kunge isina kugadzikana muchokwadi nekuti chikamu chine madziro akatetepa anozunguzika. Iyo machinist inowedzera tsigiro yechinguvana, inozivisa mugadziri, uye pamwe kudzokororwa kunotevera kwemuenzaniso weCAD kunosanganisira mbabvu inosimbisa.
Mutengo ndiyo nguva dzose makakatanwa. Precision inodhura mari-mukuderera kwemidziyo, basa reunyanzvi, maturusi, uye kuyerwa. Kukosha hakusi muchikamu chacho; iri muchikamu chinoshanda zvakakwana, nguva dzese, mugungano remutengi. Chikamu chakachipa chinokonzera kutadza kwemunda chinodhura zvakapetwa kazana kugadzirisa. Basa redu nderekutungamira vatengi kusvika padanho rechokwadi-kwete repamusoro-soro rinobvira, asi iro rakakodzera rebasa, bhajeti, uye hupenyu hwechigadzirwa chavo.
Saka kana wakatarisa a CNC chaiyo machining zvikamu mutengesi, usangotarisa pane yavo rondedzero yemuchina. Tarisa nhoroondo yavo yekugadzirisa matambudziko. Bvunza kuti vanobata sei chinyorwa chekutanga chakakundikana. Bvunza nezvehukama hwavo nevanovapa zvinhu. Bvunza kuti uone matanda avo ehupenyu hwematurusi echinhu chakafanana. Mhinduro dzemibvunzo iyoyo dzinokuudza zvakawanda kupfuura chero bhurocha ripi zvaro rinopenya. Makambani akakwenenzvera kutenderera, seQSY ine nhoroondo yemakore makumi matatu, akavaka iyo yakadzika, kazhinji yakaoma-kuhwina, kugadzira ruzivo muDNA yavo. Ndicho chega chinhu chinogara chichivharira musiyano pakati peiyo yakakwana modhi pachiratidziri uye yakavimbika chikamu mubhokisi.
