Kune basa rakasimba chaizvo, tairega muchina uchiita kudziya-kutenderera, uchicheka mweya kwemaminetsi makumi maviri kuti zvese zvigadzikane. Zvinonzwika zviri nyore, asi kusvetuka danho iri inzira iri nyore yekurasa chikamu chekutanga chezuva.
Iyo Precision muCNC Machining iSystem
Saka iwe une stock yakanaka uye yakasimba setup. Iye zvino CNC machining centre inotora. Asi hechino chinhu: iyo muchina yakataurwa yekumisikidza kurongeka chinhu chimwe chete. Kutsauswa kwechishandiso chinhu chikuru, kazhinji chisingatarisirwi. Uchishandisa chigayo chakareba, chakatetepa kusvika muhomwe yakadzika? Kunyangwe mashoma mamicrons ekukotama pamuromo anoparadza madziro ako kutwasanuka uye kupera. Isu tinorwisa izvi netoolpath strategy-kukwira milling tichipesana nemazuva ese, trochoidal milling yehomwe kuti kubatanidzwa kurambe kwakamira uye mitoro yakadzikira. Software simulation inobatsira, asi haina kumbokwana. Iwe uchiri kuda kuteerera kuchekwa. Kuchinja kwenzwi kunowanzotangira kuchinja kwechimiro.
Tool wear compensation imwe mhondi yakanyarara yekusagadzikana. Kwenguva refu yezvikamu muchinhu chakaoma senge nickel-based alloy, chishandiso chinogona kupfeka 0.02mm pamusoro pehupenyu hwayo. Kana iwe usiri kubhadharira izvo zviri muchirongwa kana ne-in-probing probing, zana rako rekupedzisira zvikamu zvichange zvisiri izvo. Apa ndipo apo kubatanidzwa kwekukanda uye machining pasi pedenga rimwe, sekuitwa neQSY, kunoratidza kukosha kwayo. Paunenge uchigadzira chikamu chaunokandawo, iwe une ruzivo rwepedyo rwekuchekwa kwechinhu, nzvimbo dzayo dzakaoma, kuparara kwayo kwechip. Ruzivo irworwo runoturikira zvakananga muhupenyu hwakasimba hwematurusi uye mhedzisiro inofanotaurwa.
Uye ngatisakanganwa chinhu chemunhu. Iyo yakanakisa CAM chirongwa chinoda machinist anoziva nguva yekupfuura mwero wekudya nekuti ruzha 'rwakadzimwa,' kana anocherekedza kuvakwa kudiki pamupendero wekuisa isati yatadza. Iyi tactile, inoongorora mhinduro loop chimwe chinhu chisina mwenje-kunze fekitori yakadzokororwa zvakakwana. Muchina unoita kufamba, asi mugadziri anopa mutongo.
Apo Precision Inosangana Nechokwadi-Nyika Basa
Ichi ndicho chikuru chezvose. Ndinoyeuka chimwe chikamu chevhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhapu. Kudhirowa kwacho kwaida kuti girazi ripere panzvimbo yakavharika. Takazviwana, zvakaisvonaka. Zvakadaro chikamu chakatadza kumanikidza kuyedzwa. Sei? Nzvimbo yekuvharisa yaive yakanyanya kutsetseka. Yaida chaiyo yekuchinjika-hatch pateni kuti ibvumidze sealant kuti ipinde zvakanaka. Taifanira kudzokera shure uye nemaune kuwedzera inodzorwa kugadzirwa. Icho chaive chidzidzo: kurongeka kunofanirwa kutsanangurwa nebasa, kwete kungoita zvekupokana Ra kukosha. A precision machining maitiro anofanirwa kuchinjika kune yekupedzisira-kushandiswa, ingave chikamu icho chiri kuenda kune chikafu-giredhi stainless pombi kana yakakwirira-tembiricha aerospace turbine.
Chimwe chiitiko chinosanganisira magungano. Unogona kuchina zvikamu zviviri kushiviriro yakasimba yemunhu mumwe nemumwe, asi kana ukasaverengera kuunganidzwa kwekushivirira mugungano, kana iwo akasiyana ekuwedzera ekuwedzera kwemafuta emidziyo, haikwane kana kushanda pamwechete pasi pemamiriro ekushanda. Dzimwe nguva, iyo chaiyo kufamba ndeyekuita nemaune chikamu chimwe pamucheto wepamusoro webhendi rekushivirira kuti rifanane nechikamu chayo chekusangana. Iyi masisitimu-chikamu kufunga kwakakosha.
Maonero ekushanda aya ndosaka kusanganiswa kwemasevhisi kuchikosha. Kambani inongoita machining chete inogona kugashira kukanda nekukanganisa kwakadzikama kunoita kuti kunyatsoenderana kusingaite. Inowanikwa isina muchina inogona kusagadzira yekugadzira. Mupi akabatanidzwa seQSY, anobata zvese kubva kugomba mold uye kukanda kwekudyara kusvika pakupedzisira CNC chaiyo machining, inogona kukwirisa iyo yese process cheni. Ivo vanogona kugadzira kukanda nemadhamu uye kubvumidzwa kwemasheya kunoita kuti chikamu chemuchina chigadzikane uye chinoshanda, mukana wakakura wezvikamu zvakaoma muaya akakosha alloys avanotaura, senge cobalt kana nickel-based.
Mutengo weKudzingirira iyo Yekupedzisira Micron
Economics ndiyo yekupedzisira, isinganzvengeki sefa. Ukama pakati pemutengo uye kushivirira hauna mutsara; zviri exponential. Kutora kushivirira kubva ± 0.05mm kusvika ± 0.025mm kunogona kupeta nguva yekugadzira uye inoda kuongororwa kwakadzama. Kuitora kubva ± 0.025mm kusvika ± 0.01mm kunogona kuipeta kana. Unoda makamuri ane air-conditioned, anononoka mafeed, anowanzo chinja maturusi, uye pamwe post-process kugaya kana kupeta. Injiniya akanaka kana mutengi ane ruzivo anoshanda nechitoro seQSY anozobvunza kuti: Kushivirira kupi kunoda kushivirira uku? Kazhinji, kuzorora iyo isiri-yakakosha dimension nebvudzi kunogona kuderedza chikamu chinodhura ne30% ne zero kukanganisa pakuita.
Mutengo wekuongorora chikamu cheizvi, zvakare. Kuyera kusvika ku0.001 kunoda midziyo yakasiyana (uye calibration) pane kuyera ku0.0001. Iyo CMM nguva haisi yemahara. Maitiro akasimba anovavarira kugona (Cp/Cpk) uko kupararira kwechisikigo kwemaitiro emuchina kuri mukati memabhendi ekushivirira, saka haufanirwe kuyera chiyero chimwe pachikamu chimwe nechimwe. Iwe unodzora maitiro, kwete kungoongorora chigadzirwa.
Apa ndipo panobhadhara kudyidzana kwenguva refu nechitoro chemuchina unokwanisa. Ivo vanodzidza zviyero zvako, iwe unodzidza kugona kwavo, uye iwe unokwanisa kugadzira nekubatana kune zvese basa uye kugadzira. Izvo zvishoma nezve kutumira RFQ yakaoma uye zvimwe nezve hurukuro inotanga, Hezvino izvo izvi zvinoda kuita. Tingazviita sei zvakanakisisa?
Kuzviputira: Kunyatsoita sePhilosophy
