Cov txheej txheem kev ua haujlwm yog kev hloov pauv ncaj qha rau ntawm cov khoom siv raw (zoo li, qhov loj me, qhov chaw, kev ua haujlwm), kom nws dhau los ua cov khoom ua tiav ib nrab lossis tiav cov txheej txheem, cov txheej txheem peb hu ua cov txheej txheem, uas yog, qhov chaw ntawm cov khoom tiav. processing benchmark, precision qhov chaw ua txheej txheem yog ntau complex.
Precision qhov chaw ua cov txheej txheem benchmark tuaj yeem muab faib ua cov txheej txheem sib txawv: casting, forging, stamping, vuam, kho cua sov, machining, sib dhos thiab lwm yam. Precision cov txheej txheem ua tiav feem ntau yog hais txog tag nrho ib feem ntawm CNC machining thiab tshuab sib dhos txheej txheem, thiab lwm yam xws li ntxuav, tshuaj xyuas, khoom siv tu, roj foob, thiab lwm yam yog cov txheej txheem pabcuam nkaus xwb. Txoj kev tig los hloov cov khoom nto ntawm cov khoom siv raw lossis cov khoom ua tiav, cov txheej txheem no peb hu ua CNC machining txheej txheem, precision qhov chaw ua kev lag luam hauv CNC machining txheej txheem yog cov txheej txheem tseem ceeb tshaj plaws.
Hauv qab no yog cov ncauj lus kom ntxaws qhia txog CNC precision qhov chaw machining txheej txheem benchmark
(1) positioning datum, positioning datum siv los ntawm lub tshuab dhos lossis fixture hauv CNC tshuab dhos rau kev ua.
(2) Kev ntsuas ntsuas, qhov ntsuas ntsuas no feem ntau yog hais txog qhov loj lossis txoj haujlwm ntawm tus qauv yuav tsum tau soj ntsuam thaum kuaj.
(3) sib dhos benchmark, qhov kev ntsuas no peb feem ntau yog hais txog txoj haujlwm ntawm cov khoom hauv cov txheej txheem kev sib dhos.
