Nyob rau hauv kev lag luam ntawm mechanical qhov chaw ua lag luam, nto roughness yog ib qho tseem ceeb heev index. Yog li koj puas paub xaiv qhov roughness ntawm qhov chaw thaum machining qhov chaw? Tom ntej no, cia kuv qhia rau koj!
Nto roughness yog ib qho tseem ceeb kev ntsuas qhov ntsuas qhov ua yuam kev ntawm microscopic geometry ntawm qhov chaw ntawm qhov chaw, yog lub hauv paus tseem ceeb rau kev tshuaj xyuas qhov zoo ntawm qhov chaw; nws yog tsim nyog los xaiv los yog tsis, ncaj qha ntsig txog qhov zoo ntawm cov khoom, kev pab lub neej thiab cov nqi ntau lawm. Mechanical qhov chaw nto roughness xaiv txoj kev muaj peb hom, uas yog, txoj kev xam, xeem txoj kev thiab analogy txoj kev. Hauv cov khoom siv tshuab tsim ua haujlwm, feem ntau daim ntawv thov yog cov qauv analog, txoj kev no yooj yim, ceev thiab siv tau zoo. Daim ntawv thov ntawm txoj kev analog yuav tsum muaj cov ntaub ntawv siv txaus, cov ntawv qhia kev tsim kho tshuab uas twb muaj lawm muab cov ntaub ntawv ntau dua thiab cov ntaub ntawv. Feem ntau siv yog qhov roughness ntawm qhov chaw uas sib haum mus rau qib kam rau ua.
Feem ntau, qhov me me ntawm qhov kev cia siab ntawm cov khoom siv tshuab, qhov me me ntawm qhov roughness tus nqi ntawm cov khoom siv tshuab, tab sis tsis muaj kev sib raug zoo ntawm lawv. Piv txwv li, qee lub tshuab, cov cuab yeej ntawm tus kov, tes log thiab cov cuab yeej siv kev noj qab haus huv, cov khoom noj khoom haus rau ntawm qhov chaw ntawm qee qhov chaw ntawm kev ua tiav, lawv cov kev cai saum npoo tau ua tiav zoo heev uas yog, qhov kev xav tau ntawm qhov roughness yog siab heev, tab sis me me kam rau ua yuav tsum tsawg heev. Mechanical qhov chaw ua feem ntau, muaj qhov ntev ntawm qhov yuav tsum tau ua ntawm cov khoom, qhov kam rau ua theem thiab qhov roughness qhov tseem ceeb ntawm los yog muaj ib qho kev sib txuas lus.
Cov saum toj no yog qhov kev xaiv ntawm deg roughness thaum machining qhov chaw, kuv vam tias nws yuav pab tau koj!
