Thaum lub cylindricity yog qhov ntsuas ntawm roundness thiab straightness raws tag nrho cov axis ntawm ib feem 3D, concentricity piv ib qho OD thiab ID los yog sib piv roundness ntawm ob lub ntsiab lus sib txawv. … Ntau qhov yooj yim dua, koj tuaj yeem txhais qhov sib txawv raws li qhov ntsuas qhov sib xws ntawm phab ntsa tuab ntawm lub raj, yeeb nkab, lossis lwm lub tog raj kheej.
Cylindricity txhais li cas?
Cylindricity yog a 3-Dimensional kam rau ua uas tswj tag nrho daim ntawv ntawm cylindrical featurekom paub meej tias nws yog puag ncig txaus thiab ncaj txaus raws nws axis. Cylindricity yog ywj siab ntawm tej datum feature lub kam rau ua yuav tsum tau tsawg tshaj li lub cheeb qhov ntev kam rau ua ntawm ib feem.
Cylindricity hauv kev kos duab yog dab tsi?
Cylindricity qhia txog qhov sib npaug thiab ncaj ntawm daim ntawv. Thaum ntsuas cylindricity, koj tab tom kuaj xyuas qhov sib txawv ntawm lub tog raj kheej, txhawm rau txheeb xyuas qhov tseeb ntawm nws daim ntawv cylindrical. Cov duab kos duab. Siv cov cuab yeej ntsuas Roundness.
Dab tsi yog qhov sib txawv ntawm qhov sib txawv thiab qhov sib txawv?
Concentricity yog suav tias yog daim ntawv ncig ntawm GD&T symmetry. Thaum symmetry ntsuas qhov tseeb midpoint dav hlau ntawm ib tug feature rau ib tug datum dav hlau los yog axis, concentricity ntsuas lub midpoint axis derived mus rau ib tug datum axis. Ob leeg yog notoriously nyuaj rau ntsuas. Runout yog kev sib xyaw ua ke thiab ncig.
Qhov txawv ntawm coaxiality thiab concentricity yog dab tsi?
Ib qhov tshwj xeeb ntawm coaxiality tshwm sim thaum ib feem ntsuas ntawm tib lub dav hlau hla, ua rau nws ntsuas 2D. Cov xwm txheej tshwj xeeb no hu ua concentricity thiab qhov piv txwv feem ntau yog piv tus ID thiab OD txheeb ze rau ib leeg ntawm lub hollow ncej lossis raj.
