Numerical control (NC) processing thev naus laus zis hais txog kev siv lub khoos phis tawj los tswj kev txav ntawm cov cuab yeej siv tshuab, uas tso cai rau kev tsim cov khoom siv hluav taws xob nrog qhov siab thiab ua haujlwm zoo. Nov yog ib qho lus piav qhia luv luv ua lus Askiv:
Numerical Control (NC) Processing Technology Overview:
Txhais:Numerical Control yog ib txoj hauv kev uas lub tshuab cuab yeej txav tau tswj los ntawm cov txheej txheem ua ntej ntawm cov lus qhia khaws cia hauv lub computer lossis lub vaj huam sib luag.
Keeb kwm:Lub tswv yim ntawm NC pib thaum xyoo 1940s nrog kev txhim kho thawj NC tshuab, uas tau siv rau kev tsim dav hlau.
Cov khoom xyaw:
Control Unit:Lub "lub hlwb" ntawm NC system uas txhais cov kev pab cuam thiab xa cov lus txib mus rau lub tshuab.
Tsav tsheb:Cov no hloov cov teeb liab tswj mus rau hauv cov lus tsa suab, txav lub tshuab axes.
Tshuab cuab yeej:Cov cuab yeej siv lub cev uas ua rau kev txiav, drilling, lossis shaping ntawm workpiece.
Workpiece:Qhov seem yog machined.
Programming:NC cov kev pab cuam raug sau ua ib hom lus tshwj xeeb (xws li G-code) uas txhais cov cuab yeej txoj hauv kev, nrawm, pub, thiab lwm yam uas tsim nyog rau kev ua haujlwm.
Qhov zoo:
Precision:NC tshuab muab siab precision thiab repeatability, uas yog ib qho tseem ceeb rau complex qhov chaw.
Kev ua tau zoo:Lawv tuaj yeem ua haujlwm tsis tu ncua, txo qis qis thiab nce kev tsim khoom.
complexity:NC thev naus laus zis tuaj yeem tsim cov khoom nrog cov geometry nyuaj uas nyuaj lossis tsis tuaj yeem tsim manually.
Tus nqi:Thaum cov nqi pib yog siab, qhov txo qis rau cov neeg ua haujlwm txawj thiab kev ua haujlwm tau zoo tuaj yeem ua rau cov nqi txuag nyiaj ntau dhau sijhawm.
Daim ntawv thov:
Machining Centers:Siv rau milling, drilling, thiab tho txawv.
Tshuab dhos:Rau txoj haujlwm tig los tsim cov khoom cylindrical.
Sib tsoo tshuab:Ua kom tiav zoo kawg nkaus ntawm qhov chaw.
Routers:Rau woodworking thiab lwm yam khoom shaping.
Hom ntawm NC:
Computer Numerical Control (CNC):Daim ntawv tshaj plaws uas siv lub computer los tswj lub tshuab.
Direct Numerical Control (DNC):Qhov twg ntau lub tshuab yog tswj los ntawm lub hauv paus computer.
Yav tom ntej Trends:
Kev koom ua ke nrog CAD / CAM:Seamless kev koom ua ke ntawm kev tsim thiab kev tsim khoom.
Advanced Materials:Kev siv NC rau kev ua haujlwm nrog cov ntaub ntawv tshiab xws li cov khoom sib xyaw thiab cov ceramics.
Automation:Nce qib ntawm automation, nrog rau cov neeg hlau thauj khoom thiab tshem tawm.
Kev sib tw:
Cov neeg ua haujlwm txawj:Yuav tsum muaj cov kws txawj tshaj lij los ua haujlwm thiab tswj cov tshuab NC.
Tus nqi:Kev nqis peev thawj zaug hauv NC tshuab thiab software tuaj yeem ua tau ntau yam.
complexity:Programming NC tshuab xav tau kev nkag siab zoo ntawm cov txheej txheem machining.
NC thev naus laus zis tau hloov pauv kev tsim khoom los ntawm kev muab ib txoj hauv kev los tsim cov khoom siv nrog kev ua haujlwm siab thiab sib xws, uas yog qhov tseem ceeb rau kev lag luam xws li aerospace, automotive, thiab kev tsim khoom siv kho mob.
