Dab tsi yog qhov teeb meem uas cuam tshuam rau qhov npoo ntawm qhov sib txuam ntawm cov cuab yeej? Qhov saum npoo roughness txiav txim siab qhov zoo ntawm qhov chaw. Qhov ntau dua cov roughness, qhov zoo dua qhov zoo ntawm qhov chaw. Yam hais lus, qhov peb tshwm sim hauv qab no cuam tshuam rau qhov chaw npoo ntawm qhov ua kom hlau: Qhov:
Ua ntej, lub cev nqaij daim tawv tseem ceeb, hauv kev ua haujlwm ntawm lub sijhawm ua haujlwm, lub fillet thiab lub plhaub ntawm cov hniav tuaj yeem deform hlau cov khoom, uas yuav ua rau cov dej npau ntawm qhov yuav ua rau mob loj heev. Nyob rau hauv kev ua ntawm cov khoom yas, lub chipping yuav tsim ib tug nti vim tsim ntawm ib tug nti. Yob, thiab hardness yog heev. Cov tsos ntawm lub ntug kev ntes tau zoo nkauj heev, yog li nws yog qhov yooj yim rau qhov chaw ntawm lub workpiece kom tshwm sim tsis muaj riam cim. Qhov no yuav ua rau lub qhov muag tsis pom kev ntawm qhov khoom
Qhov thib ob, cov txheej txheem ntawm txoj kev xav, ntawm qhov kev paub meej ntawm peb cov cuab yeej ua technology, muaj ntau yam tseem ceeb uas yuav cuam tshuam rau qhov chaw npau taws, feem ntau ntawm cov khoom ntuag, cov khoom ua haujlwm, kev tswj cov zauv thiab lwm yam.
Qeb peb, cov duab geometric, feem ntau yog raug rau cov duab ntawm lub cuab tam, tsis meej, tsis meej, thiab lwm yam yuav raug cuam tshuam los ntawm qhov chaw npoo
