Kev Tswj Hluas Kawg tshuab Computer (CNC) yog kev lag luag tshuab uas qhia txog kev tsim kho tshuab ntau yam ntxiv rau hauv kev tsim kho no, nyob hauv kev lag luag tshuab tseem ceeb uas muaj computer leej twg sib cuam tshuam nrog rau hauv tshuab los tswj kev ua haujlwm nrog kev nceej ntsiab thiab kev pheej hmoo zoo dua. CNC muaj qhov chaw tseem ceeb uas sib cuam tshuam nrog peb qhov chaw: chav tswj tshuab (MCU), kev tswj hluas kawg thiab cov sensors tshuaj xyuas. MCU, lossis daim computer siv rau hauv tshuab, yog qhov tseem ceeb. Nws txhais lus rau cov luj lus uas tsim los ntawm software CAD/CAM (lus code G thiab M), thiab sau cov lus code no mus rau hauv daim duab tshuab. Cov duab no command rau cov moter servomotors thiab ball screws kom tso tshuab mus rau qhov chaw uas xav tau nrog kev nceej ntsiab. Qhov tseem ceeb tshaj plaws yog system "closed-loop", uas txhais tau tias cov rotary encoders lossis linear scales feem ntau tshuaj xyuas qhov chaw thiab kev ntev ntawm tshuab thiab vaj tse, thiab rov sau cov ntaub ntawv no mus rau MCU. Computer rov soj nqi cov ntaub ntawv no nrog qhov chaw uas tau command, thiab ua cov kev hloov tsawg tsawg kom tshem tawm qhov sib txawv. Qhov loop feedback no yog qhov pab tshuab CNC kom nceej ntsiab nrog micron. Txhawm rau beyond control kev nqaj, CNC tswj tag nrho qhov kev tsim kho: nws tswj kev ntev ntawm spindle thiab torque, tswj kev flow ntawm coolant, ua automatic tool changes, thiab tshuaj xyuas cov teeb meem zoo li tool breakage lossis load loj heev. Cov CNC systems tam sim no kuj yog qhov tsho rau Industry 4.0, muaj kev sib txuas rau network los muab programs (DNC), rov ntaub ntawv tshuab rau analytics, thiab tso kom muaj kev sib txuas los tshuaj xyuas thiab kho tej kuv tshuab. Qhov digital backbone no pab tsim cov duab ntau yam, los ntawm 2D profiles tsuaj mus rau 3D surfaces tshaib, rau hauv ntau yam khoom. Nyob ze, CNC tsis yog automation xwb; nws yog kev digital ntawm kev tsim kho phooj ywg, hloov digital design mus rau phooj ywg nceej ntsiab nrog kev ua haujlwm tshuab uas pab nceej ntsiab, nyob ib txhiab, thiab zoo dua li kev tsim kho los ntawm tiam.
