Lub khoos phis tawm tau yooj yim rau ntau qhov chaw ntawm peb lub neej. Tam sim no, CAD (Khoos phib tawj Aided Design) siv rau txhua qhov ntawm kev tshawb fawb thiab thev naus laus zis. Kev tsim qauv thiab tsim cov duab kos uas siv cov khoos phis tawm ntawm lub tshuab ua rau cov khoom lag luam tsim tau zoo dua qub. Cov duab kos duab kos rau ntawm daim ntawv nrog xaum, cov pas ntsuas thiab cov khoom siv ntsuas yog yuav luag ib yam ntawm yav dhau los. Tam sim no, muaj ntau txoj haujlwm nrog uas koj tuaj yeem ua peb-txheej qauv thiab kos duab.
Cov Lus Qhia
Kauj ruam 1
Txhawm rau ua kom muaj teeb duab ntawm lub computer, koj yuav tsum txiav txim siab hauv qhov program twg koj xav ua nws thiab nruab qhov program no ntawm koj lub khoos phis tawm. Cov txheej txheem ntawm kev tsim qauv computer thiab kos duab zoo ib yam hauv txhua qhov kev zov me nyuam, tab sis nws siv sijhawm los kawm kom tau thiab siv tau rau txhua qhov kev kawm. Yog li no, sim xaiv qhov program uas haum rau koj zoo tshaj plaws, paub nws thiab tom qab ntawd ua haujlwm rau hauv xwb.
Kauj ruam 2
Peb qho program thib 3 ntawm thaj chaw no yog CATIA v5, ProEngineer thiab Unigraphics. Cov kev pab cuam no muaj qauv dav dav heev 3D thiab qauv tsim cov peev txheej, tab sis lawv xav tau lub khoos phis tawm ua haujlwm siab. Cov phiaj xwm no tau tsom mus rau kev tsim cov qauv peb-seem thiab tom qab ntawd tsim cov duab kos raws cov qauv no. Cov phiaj xwm hauv qab no yog qhov yooj yim thiab tsis xav tau ntawm lub computer ua haujlwm: AutoCAD, Solidworks thiab Compass. Rau kev kos duab yooj yim, AutoCAD yog qhov kev siv ntau tshaj plaws.
Kauj ruam 3
Txhawm rau tsim cov duab kos, qhib qhov kev xaiv uas raug xaiv thiab tsim kev kos duab tshiab. Tom ntej no, tau xaiv cov hom duab kos, pib kos duab. Txhua qhov kev zov me nyuam muaj cov cuab yeej siv nrog cov ua haujlwm yooj yim tshaj plaws (taw tes, kab, voj voog). Geometry yooj yim yog tsim tsa siv cov neeg ua hauj lwm no. Kuj tseem muaj cov cuab yeej siv nrog cov neeg ua haujlwm siab (ua kom tiav, mirroring, ntsuas). Tom qab tsim txoj kab ntsuas cov siv ntsuas vaj huam sib luag, qhov ntev tau teem rau hauv cov duab. Tom qab ntawd, cov duab kos tau luam tawm.
