Kana vanhu vazhinji vakanzwa 'CNC machining nemazvo,' vanobva vafunga nezve kushivirira kwakasimba, senge ± 0.001 inches kana 5 microns. Ndiyo hurukuro yebhurocha. Iyo chaiyo nyaya, iyo inochengeta zvitoro pasi maneja husiku, ndeye kuenderana, kwete nhamba chete pane spec sheet. Ndiwo mutsauko uripo pakati pekurova kushivirira pachikamu chimwe chakakwana uye kuibata ichipfuura mazana mashanu, kuburikidza nekupfeka kwemidziyo, kudonha kwemafuta, uye kusawirirana kwezvinhu. Ndipo panowanikwa hunyanzvi chaihwo, uye mutengo chaiwo.
Iyo Illusion yeiyo Yakakwana Dhinda
Ndakaona akawanda madhirowa achiuya aine chimwe nechimwe chinhu chakamisikidzwa pane kumwe kushivirira kwehupenzi, kunge ± 0.0002. Inodanidzira kuti mugadziri haana kumbomira pamushini. Vari kuvhara mabhesi avo, asi zvinoita kuti basa ridhure zvisina basa. Kurongeka kwechokwadi muCNC machining kunotanga nehungwaru dhizaini. Kushivirira ikoko kunogona kurerutswa here kana kuri pachiso chisina kutsoropodza? Chikamu chacho chinoda kupedzisa ikoko pane zvese here? Akanaka machinist, kana mudiwa akanaka seQSY, anosundidzira kumashure pane izvo zvinodhinda. Hazvisi zvekucheka makona; ndezvekushandisa nemazvo pazvine basa. Kupambadza nhamburiko pazviyerero zvisina-akakosha inzira yechokwadi yekuputira bhajeti chimbo chekutanga chisati chabata simbi.
Kusarudzwa kwezvinhu ndiye mudzvanyiriri akanyarara wekururama. Iwe unogona kuronga yakanakisa nzira yekushandisa yealuminium, asi edza nzira imwechete pagummy 304 isina tsvina kana yakaomeswa simbi yesimbi, uye iwe unozoona yako chaiyo ichibuda. Izvo zvinhu zvinorwa zvakare. Inotsauka, inopisa, inoshanda-inoomesa. Kushanda neakakosha alloys QSY inotaura-nickel-based, cobalt-based-inowedzera imwe layer. Idzi hadzisi simbi dzakaoma; vanozvibata zvakasiyana pasi pemucheki. Mafidhi ako, kumhanya, uye kunyangwe zano rematurusi rinofanirwa kuvakwa zvakatenderedza hunhu hwezvinhu, kwete kungooma kwayo chiyero. Kuwana kunyatsojeka pano kushoma pamusoro pekugona kwemuchina uye zvimwe nezve ruzivo rwemugadziri.
Ipapo pane setup. Apa ndipo panozvarwa 80% yekukanganisa chaiko, mune yangu ruzivo. Vise inosvika churu kubva mukufanana, chiumbwa chisina kugariswa chakati chechetere nekuda kwebura diki, mhunga ine guruva - zvese zvinowanda. Ndakadzidza izvi nenzira yakaoma pakutanga, ndichidzingirira nyaya yekumhanya pane imwe lathe kwemaawa, ndokuzongowana kanenge kasingaonekwe chip chakasungwa pasi peshaya. Muchina wacho wakanga wakakwana; nzira yangu yakanga isiri. Iye zvino, hafu yeawa yekutanga yebasa ripi neripi ingori kuchenesa, kutarisa, uye kuratidza. Inonzwa ichinonoka, asi ndiyo nzira inokurumidza kuenda kune yakanaka chikamu.
Zvishandiso, Thermal Drift, uye Kurume Kwenguva
Kupfeka kwemidziyo haina mutsara, uye muvengi we batch chaiyo. Iwe unogona kufona mune nyowani-itsva endmill uye uwane mibairo yakanaka. Asi mushure mezvikamu makumi mashanu, chishandiso icho chakarasa micron yemupendero wayo. Chikamu chichiri kutaridzika zvakanaka, asi zviyero zvakachinja zvine hungwaru.
