Deg roughness hais txog qhov tsis sib xws ntawm cov txheej txheem ua tiav nrog qhov sib txawv me me thiab cov ncov me me thiab hav. Qhov kev ncua deb (yoj nrug) nruab nrab ntawm ob yoj crests los yog ob yoj troughs yog heev me me (tsawg dua 1 hli), uas yog ib tug microscopic geometric yuam kev. Qhov me me ntawm qhov roughness, qhov smoother ntawm qhov chaw. Feem ntau, cov yam ntxwv morphological nrog yoj nrug tsawg dua 1 hli yog ntaus nqi rau saum npoo av, cov yam ntxwv morphological nrog qhov loj ntawm 1 mus rau 10 hli yog txhais tau tias yog qhov chaw waviness, thiab cov yam ntxwv morphological nrog qhov loj dua 10 hli yog txhais raws li qhov chaw topography.
Surface roughness feem ntau tshwm sim los ntawm kev ua cov txheej txheem siv thiab lwm yam, xws li kev sib txhuam ntawm cov cuab yeej thiab qhov chaw nto thaum lub sij hawm ua cov txheej txheem, cov yas deformation ntawm cov hlau nto thaum chips sib cais, high-frequency vibration hauv txheej txheem txheej txheem. , thiab lwm yam. Vim yog cov txheej txheem ua haujlwm sib txawv thiab cov khoom siv ua haujlwm, qhov tob, qhov ntom ntom, cov duab thiab kev ntxhib los mos ntawm cov qhab nia sab laug ntawm cov txheej txheem txheej txheem sib txawv.
Nto roughness yog ze ze rau qhov sib txuam ua haujlwm, hnav tsis kam, qaug zog lub zog, tiv tauj nruj, kev vibration thiab suab nrov ntawm cov khoom siv kho tshuab, thiab muaj kev cuam tshuam tseem ceeb rau kev pab cuam lub neej thiab kev ntseeg siab ntawm cov khoom siv tshuab.
Kev ntsuas ntsuas
qhov siab yam ntxwv parameter
Contour arithmetic txhais tau tias sib txawv Ra: tus lej lej ntawm tus nqi kiag li ntawm qhov contour offset hauv qhov piv txwv ntev lr. Hauv kev ntsuas qhov tseeb, qhov ntsuas ntsuas ntau dua, qhov tseeb Ra yog.
Qhov siab tshaj plaws profile Rz: qhov kev ncua deb ntawm cov kab siab kawg thiab kab hauv qab ntawm lub hav.
Kev soj ntsuam hauv paus
Qauv ntev
Qhov ntsuas qhov ntev lr yog qhov ntev ntawm cov kab siv tau teev tseg rau kev ntsuas qhov roughness. Qhov ntsuas qhov ntev yuav tsum raug xaiv raws li qhov tseeb ntawm qhov tsim thiab kev ntxhib los mos ntawm qhov, thiab qhov ntev yuav tsum raug xaiv los cuam tshuam cov yam ntxwv ntawm qhov roughness. Qhov ntsuas qhov ntev yuav tsum ntsuas nyob rau hauv cov kev taw qhia ntawm qhov tseeb qhov profile. Qhov ntsuas qhov ntev yog teev thiab xaiv los txwv thiab txo qhov cuam tshuam ntawm qhov chaw waviness thiab daim ntawv yuam kev ntawm qhov ntsuas qhov roughness.
Nyob rau hauv lub tshav pob ntawm mechanical processing, drawings xws li hlau stamping qhov chaw, sheet hlau qhov chaw, machined qhov chaw, thiab lwm yam yog dav cim nrog cov khoom nto roughness yuav tsum tau. Yog li ntawd, nyob rau hauv ntau yam industries xws li nws pib qhov chaw, engineering machinery, kho mob, aerospace, thiab shipbuilding machinery, thiab lwm yam. Tag nrho cov yuav pom.
