Qhov tseeb ntawm ib theem yog dab tsi, thiab qhov ntev dua theem, qhov tseeb yog qhov tseeb
Qhov tseeb ntawm ib theem yog hais txog lub axial txav ntawm theem npuas thiab lub qaij lub kaum sab xis thaum qhov chaw ntawm lub npuas coincides nrog lub symmetrical centre ntawm sab laug thiab txoj cai cim kab thaum lub theem nyob rau ntawm ib tug teev kab rov tav qaij kaum. Feem ntau, qhov tseeb ntawm ib qib yog cuam tshuam nrog ntau yam. Yog li, qhov tseeb ntawm ib theem yog dab tsi?
Qhov tseeb qhov kev faib tawm ntawm ib qib yog qhia nyob rau hauv cov lej, hauv mm / m. Piv txwv li, ib qib nrog qhov tseeb ntawm {{0}}.75mm / m yog siv, thiab qhov yuam kev ib m ntsuas los ntawm qib tsis tshaj 0.75mm. Qhov tseeb ntawm ib qib feem ntau suav nrog cov hauv qab no: 0.25mm/m, cov ces kaum qhia raws li 0.{{10}}}143 degree , 0.5mm /m, cov ces kaum qhia raws li 0. , cov ces kaum qhia raws li 0.0859 degree, 2mm / m, thiab cov ces kaum qhia li 0.1146 degree.
Yog qhov ntev dua qib, qhov tseeb dua nws yog
Thaum ntsuas seb ib yam khoom puas nyob rau hauv kab rov tav, ib theem feem ntau yog siv, thiab nws yog ib qho tsim nyog los xaiv ib qib uas tsim nyog raws li txoj haujlwm xav tau. Ntau tus phooj ywg ntseeg tias qhov ntev dua, qhov siab dua qhov tseeb. Qhov no puas yog?
Qhov tseeb, nws tsis yog qhov tseeb tias qhov ntev dua qib, qhov tseeb yog qhov tseeb. Nws kuj nyob ntawm qhov khoom ntsuas nws tus kheej. Piv txwv li, yog tias ib qho khoom luv luv yog ntsuas, qib ntev dua yuav tsis raug. Txawm li cas los xij, ib qib feem ntau muaj ntau qhov ntsuas, ob qho tib si horizontally thiab vertically. Kuj tseem muaj hom kev ncua deb, uas yog tsim los ntawm ob ntu uas tuaj yeem sib cais rau kev ntsuas: sab laug thiab txoj cai kav. Hom qib no tuaj yeem siv rau ob qho tib si ntsuas qhov deb thiab ntsuas qhov ntev, thiab nws kuj tseem siv tau yooj yim.
Feem ntau, qhov ntev dua theem, qhov tseeb yog qhov tseeb. Nws kuj yog nyob ntawm qhov ncaj ntawm cov khoom, qhov zoo ntawm cov npuas leveling, phab ntsa thickness ntawm tus pas ntsuas, thiab seb lub hauv paus ntawm lub benchmark tau precisely milled. Thaum xaiv, ib qib uas tsim nyog raug xaiv tau raws li qhov xav tau ntawm cov khoom ntsuas thiab qhov xwm txheej tiag tiag.
