Txoj Kev Tawm Tawm Yog Dab Tsi?
Cov kab khiav tawm, tseem hu ua kab tawm suab thiab cov kab tawm sab nraud, yog cov txheej txheem coj los siv los ua kom cov kev sib txig sib txig sib luag. Lawv tuaj yeem pom muaj nyob rau hauv 3D printers, CNC mills, waterjet cutters, thiab cov zoo li.
Txoj kev tsheb nqaj hlau muaj txoj hlua, hlau txhuam, uas yog lub caij tsheb sib tsoo. Feem ntau, lub carriage muaj lub npas npav rov qab uas muaj cov ntsiab lus sib cuag ntawm txoj kev sib tw thiab txoj kev tsheb nqaj hlau, raws li pom saum toj no. Qhov no ua rau cov lus tsa suab zawv zawg li lub npas ntawm cov chaw. Cov duab ntawm lub phaj ua kom lub tsheb npav nyob hauv xauv nrawm nrog kev sib zog, kev txwv cov lus taw kev rau cov lus qhia ncaj qha.
Tawm rail 3D printers siv ntau qhov zoo ntawm txoj kev tawm ncaj qha mus rau, supposedly, ua tau zoo dua cov lus tsa suab. Li ntawd, li cas yog cov lus pom zoo? Cia wb mus saib.
Zoo Tshaj Plaws
Feem ntau cov 3D printers kev ua si sib xyaw tawv-hlua phom, siv nyob rau hauv tandem nrog lub pob bearings. Qhov kev sib txuam no tau ua haujlwm zoo rau ntau txhiab tus luam ntawv thiab cov neeg siv, yog dab tsi ntxiv ua linear ntsia coj?
Cov kab tawm ncaj qha yog qhov tseeb. Tawm txoj hlua flex tsawg dua li cov hlua khau tawm, vim muaj tej yam xws li cov duab thiab hlau nruj. Tsis ntseeg? Sim ua rau koj tus kheej khoov, thiab muab piv rau ib tus pas nrig ncaj qha. Cov tsheb npav dlhau yuav muaj tsawg dua. Nyob rau hauv cov nqe lus ntawm 3D luam tawm, qhov no ua rau kom zoo heev txo backlash thiab ringing artifacts, yielding nqus cov phab ntsa thiab npoo.
Koj tuaj yeem khiav deb nrog ib txoj kab tsheb npav. Tsis zoo li cov hlua khau tawm, cov hlua ncaj qha tsis pub rau kev sib tw ntawm txoj kev thauj khoom. Qhov no txhais tau hais tias, thaum tsim tsa cov suab lus tsa suab, ib txoj kev tsheb nqaj hlau tuaj yeem ua tiav ncaj qha ncaj nraim ntawm nws tus kheej, raws li tau hais los saum no. Nrog cov hlua ncaj qha, tsawg kawg yog ob qho tsim nyog los tiv thaiv kev sib hloov, ua rau muaj teeb meem nrog kev ua kom zoo thiab qhia txog qhov ceeb thawj. Siv lub voj hlau tawm tau yooj yim, sib dua, sib koom ua ke, uas tseem yuav txo cov ntawv luam 3D.
Kev siab dua, kev txav siab ncaj ncees. Cov kab khiav tawm kuj feem ntau ua rau ntau lub nrawm tolerances dua li tus pas hlua. Qhov kev txiav txim siab dua no txhais tau tias txo kev ua si thiab kev txiav txim siab (thaum tuav cov kabmob ntes thiab tsis txav ntseeg nkaws).
Yooj yim, ntau meej mounting. Tawm txoj kab yog qhov yooj yim dua rau qhov nce tshaj rods. Cov kev sib tw thiab lub tsheb thauj khoom ob qho tib si muaj qhov sib txuas ntawm qhov chaw nruab nrab, ces ob peb lub bolts yuav muaj txhua yam xauv cia. Qhov no ua rau muaj kev sib txuas nrog cov hlua khau thiab bearings, nws hloov daim duab yuav tsum muaj ntau yam muaj tswv yim, thiab feem ntau tsawg dua, kev daws teeb meem hauv 3D printers.
Disadvantages
Ntawm chav kawm, tsis muaj dab tsi yog zoo meej. Nyob rau hauv ob peb cheeb tsam, txoj hlua tawm tsis qis ntawm cov pas nrig hauv 3D daim ntawv sau npe.
Tawm txoj kab yog kim. Yog tsis muaj qhov ntawd. Cov tsheb npav ncaj ncees yuav yooj yim heev dua ob peb zaug ntau tshaj li cov sib lawv li qub tawm ntawm cov pas nrig thiab cov kabmob. Tus nqi muaj nqis, qhov mob loj, thiab cov lus tsa suab ncaj ncees tuaj ntawm tus nqi sib npaug.
Cov kab khiav tawm yuav tsum tau saib xyuas nrog kev saib xyuas. Tsis zoo li cov kabmob uas tsis muaj kabmob, cov kabmob npav hauv cov kab tsheb uas tsis muaj tsheb tsis yog feem ntau capped thiab muab xauv hauv. Yog tias lub tsheb tsis dhau lub tsheb ciav hlau, qee cov npas pob yuav tawm, ua rau tsis sib luag.
