Nrog rau txoj kev loj hlob ntawm machining tshuab, ntau yam tshiab machining mechanisms tau tshwm sim, yog li nyob rau hauv precision machining, tshwj xeeb tshaj yog nyob rau hauv micro machining, raws li kev tsim mechanism thiab cov yam ntxwv ntawm qhov chaw. Nws muab faib ua peb pawg: kev tshem tawm, ua ke ua ke thiab deformation ua. Kev tshem tawm, tseem hu ua kev sib cais, yog kev siv lub zog, cua sov, hluav taws xob, lub teeb thiab lwm yam txheej txheem los tshem tawm ib feem ntawm cov khoom siv los ntawm cov khoom ua haujlwm, xws li txiav, sib tsoo, hluav taws xob ua, thiab lwm yam.
Kev sib xyaw ua ke ntawm kev ua haujlwm yog siv lub cev thiab tshuaj txoj hauv kev los txuas (kev tso nyiaj), txhaj tshuaj (infiltrate), thiab txuas ib txheej ntawm cov khoom sib txawv ntawm qhov chaw ua haujlwm, xws li electroplating, vapor deposition, oxidation, carburizing, bonding, welding, thiab lwm yam. Deformation processing yog siv lub zog, kub, molecular motion thiab lwm yam txhais tau tias deform lub workpiece hloov nws loj, zoo li qub thiab kev ua tau zoo, xws li casting, forging thiab lwm yam.
Nws tuaj yeem pom tias lub tswv yim ntawm kev ua tiav tau tawg los ntawm cov txheej txheem kev tshem tawm ib txwm muaj, thiab muaj cov yam ntxwv ntawm kev sib sau, kev loj hlob, deformation, thiab lwm yam, thiab tib lub sij hawm hais txog kev kho deg, tsim cov txheej txheem txheej txheem.
Technology thiab txheej txheem zoo ntawm precision machining
Piv nrog rau cov txheej txheem chipless, qhov zoo ntawm precision machining ntawm machining yog thawj zaug ntawm tag nrho cov, tsis tsuas yog cov khoom siab tshem tawm tus nqi, tab sis kuj zoo kev lag luam. Qhov no yog cov ntaub ntawv, piv txwv li, piv rau cov txheej txheem laser plasma machining; qhov no yog vim tias cov txheej txheem no tam sim no tsuas yog muab ntau lub zog kom ua tiav cov khoom tshem tawm siab; ntawm qhov tod tes, seb cov txheej txheem ua haujlwm puas tuaj yeem ua tau raws li qhov yuav tsum tau muaj thiab qhov tseeb ntawm qhov yuav tsum muaj teeb meem.
Chipless xovxwm machining feem ntau yog siv rau kev tsim khoom loj, thiab feem ntau yuav tsum tau ua haujlwm tom qab txiav kom tau txais cov khoom tsim nyog kawg nkaus. Yog li ntawd, lub ntsiab kom zoo dua ntawm machining yog pab kom lub workpiece kom tiav precision dua.
