Qee qhov ntawm cov khoom raug tshem tawm, thaum cov seem seem ua burrs ntawm lub qhov tawm. Cov duab thiab qhov loj ntawm qhov tawm burrs sib txawv, cuam tshuam los ntawm kev txiav tsis thiab cov cuab yeej geometry. Kev tshuaj xyuas cov hom burrs pab kawm ntxiv txog lawv cov txheej txheem tsim.
Cov kev tshawb fawb tau pom tias burrs tsim thaum lub sij hawm titanium alloy drilling tuaj yeem muab faib ua hom hauv qab no:
Uniform Burrs: Burrs uas tsim uniformly nyob ib ncig ntawm qhov tawm.
Uniform Burrs nrog Drilling Cap: Burrs nrog cov khoom seem ua ib qho zoo sib xws.
Crown-zoo li Burrs: Burrs nrog lub kaus mom-zoo li lossis tsis zoo.
Ntau tus kws tshawb fawb tau pom los ntawm kev sim thiab simulations tias yam xws li workpiece nruj, cov khoom siv, thiab txiav tsis cuam tshuam cuam tshuam rau burr morphology. Txawm hais tias tsis muaj cov txheej txheem kev sib koom ua ke, thawj hom burrs yog peb tau hais los saum no.
3. Tsim Mechanisms ntawm Burrs ntawm Kev Tawm ntawm Titanium Alloy Drilling
Thaum lub sij hawm drilling txheej txheem ntawm titanium alloys, tsim ntawm burrs yog ze ze rau cov khoom yas deformation thiab txiav ntug ntawm cov cuab yeej. Kev tshawb fawb tau pom tias kev tsim cov burrs ntawm qhov tawm ntawm qhov drilling tuaj yeem muab faib ua ntau theem, feem ntau cuam tshuam los ntawm kev txiav quab yuam, qhov kub thiab txias, thiab cov cuab yeej geometry.
Cov txheej txheem ntawm kev tsim burr feem ntau suav nrog cov kauj ruam hauv qab no:
Thaum txiav, cov khoom nyob rau hauv qab ntawm lub qhov undergoes yas deformation.
Cov khoom seem raug thawb mus rau lub qhov tawm ntawm lub laum me ntsis.
Thaum cov khoom dhau ntawm qhov tawm ntawm ntug, nws pib ncab thiab tawg, nws thiaj li tsim burrs.
Tsis tas li ntawd, los ntawm cov txheej txheem simulation, nws tau pom tias lub cuab yeej geometric lub kaum sab xis, txiav tsis, thiab txiav qhov kub thiab txias muaj qhov cuam tshuam loj rau kev tsim burr. Kev sib txawv ntawm kev txiav thiab cov cuab yeej cuab tam tuaj yeem ua rau tsim ntau hom burrs. Piv txwv li, tus nqi qis qis thiab siab ntxaiv ceev feem ntau tsim cov burrs zoo ib yam, thaum cov khoom noj siab tuaj yeem ua rau lub kaus mom- zoo li burrs.
4. Tswj cov tswv yim rau Burrs ntawm Kev Tawm ntawm Titanium Alloy Drilling
Txhawm rau hais txog kev tsim cov burr hauv titanium alloy drilling, cov kws tshawb fawb tau npaj ntau lub tswv yim tswj, feem ntau suav nrog kev ua kom zoo rau kev txiav, cov cuab yeej tsim, thiab cov txheej txheem machining.
