Rapid Pwm Rau Lub Tebchaws Yelemees

Raws li nrog CNC rho tawm txoj kev, lub computer-aided-design - computer-aided manufacturing CAD -CAM workflow nyob rau hauv cov tsoos Rapid Prototyping txheej txheem pib nrog cov creation ntawm geometric cov ntaub ntawv, xws li ib tug 3D khoom siv ib tug CAD workstation, los yog 2D slices siv a tshuab luam ntawv. Rau Rapid prototyping cov ntaub ntawv no yuav tsum sawv cev rau tus qauv geometric siv tau; xws li, ib tug uas nws ciam teb nto npog ib tug finite ntim, tsis muaj qhov exposing sab hauv, thiab tsis txhob quav rov qab rau lawv tus kheej. Hauv lwm lo lus, cov khoom yuav tsum muaj "sab hauv". Tus qauv siv tau yog tias rau txhua qhov chaw hauv 3D qhov chaw lub khoos phis tawj tuaj yeem txiav txim siab seb qhov taw qhia ntawd nyob hauv, rau, lossis sab nraud ntawm thaj tsam ntawm tus qauv. CAD post-processors yuav kwv yees li ntawm daim ntawv thov cov neeg muag khoom 'cov ntaub ntawv CAD geometric sab hauv (piv txwv li, B-splines) nrog rau daim ntawv lej yooj yim, uas nyob rau hauv lem tau qhia nyob rau hauv cov ntaub ntawv teev hom ntawv uas yog ib tug ntau feature nyob rau hauv additive manufacturing: STL (stereolithography) tus qauv de facto rau kev hloov cov qauv duab geometric rau SFF cov cav tov.
