Taw qhia
CNC stands rau Computer Numerical Control. Nws yog cov txheej txheem tsim khoom uas suav nrog kev siv computer software los tswj kev txav ntawm cov cuab yeej siv tshuab. Hauv kab lus hauv qab no, peb yuav tshawb txog keeb kwm ntawm CNC, nws cov kev siv ntau yam, thiab cov txiaj ntsig uas tuaj nrog kev siv hauv kev tsim khoom.
Keeb kwm ntawm CNC
Lub keeb kwm ntawm CNC rov qab mus rau thaum xaus ntawm 1940s thaum John Parsons, ib tug engineer ntawm Massachusetts Institute of Technology (MIT), koom tes nrog Frank Stulen ntawm US Air Force's Wright-Patterson Air Force Base los tsim ib txoj hauv kev rau automating. kev tsim cov dav hlau helicopter.
Parsons thiab Stulen tau tsim ib lub kaw lus ntawm cov ntawv punch thiab hydraulic actuators uas tuaj yeem tswj kev txav ntawm lub cuab yeej txiav. Qhov system no yog qhov ua ntej rau Computer Numerical Control, uas tau tsim nyob rau xyoo 1950 thiab 1960s.
Thaum ntxov ntawm CNC, thev naus laus zis tau txwv thiab kim, thiab tsuas yog cov tuam txhab loj tuaj yeem them taus los nqis peev hauv nws. Txawm li cas los xij, kev nce qib hauv kev suav thiab kev tsim kho software tau ua rau CNC pheej yig dua thiab siv tau rau cov tuam txhab me.
CNC ua haujlwm li cas
CNC yog cov txheej txheem tsim khoom siv computer software los tswj kev txav ntawm cov cuab yeej siv tshuab. Lub software tsim ib txheej ntawm cov lus qhia uas qhia lub tshuab thaum twg thiab qhov twg yuav txav mus, nrog rau ntau npaum li cas cov khoom yuav tshem tawm.
Lub tshuab yog nruab nrog axes uas txav cov cuab yeej txiav raws txoj kev uas tau teem tseg. Lub software tswj kev txav ntawm cov axes, tso cai rau lub tshuab tsim cov kev txiav txim siab me me uas tsis muaj kev cuam tshuam rau tib neeg.
Muaj peb hom tshuab uas siv CNC: tshuab tig, tshuab milling, thiab hluav taws xob tawm tshuab (EDMs). Txhua lub tshuab no muaj peev xwm sib txawv thiab haum rau ntau hom kev tsim khoom.
Kev siv ntawm CNC
CNC yog siv nyob rau hauv ntau yam kev lag luam, xws li aerospace, automotive, kho mob, thiab electronics. Nws yog feem ntau siv los tsim cov khoom sib txuam nrog nruj tolerances uas yuav nyuaj rau kev ua tiav siv cov txheej txheem ib txwm muaj.
Hauv kev lag luam aerospace, CNC yog siv los tsim cov khoom siv rau cov tshuab dav hlau, tsaws iav, thiab cov qauv dav hlau. CNC kuj tseem siv los tsim cov kev cai prosthetics thiab orthotics hauv kev lag luam kho mob.
Hauv kev lag luam automotive, CNC yog siv los tsim cov khoom siv cav, qhov raug tshem tawm, thiab lub cev vaj huam sib luag. Nws kuj yog siv rau hauv kev tsim cov cuab yeej tshwj xeeb thiab cov cuab yeej siv hauv kev tsim khoom.
Hauv kev lag luam hluav taws xob, CNC yog siv los tsim cov ntawv luam tawm Circuit Board (PCBs) thiab lwm yam khoom siv hluav taws xob. CNC tshuab tuaj yeem tsim cov txiav thiab qhov hauv PCBs, tso cai rau cov khoom siv hluav taws xob me me.
Cov txiaj ntsig ntawm CNC
Muaj ntau cov txiaj ntsig uas tuaj nrog kev siv CNC hauv kev tsim khoom. Ib qho ntawm qhov zoo tshaj plaws ntawm CNC yog nws lub peev xwm los tsim cov khoom nyuaj nrog kev ua siab ntev. CNC tshuab tuaj yeem tsim cov khoom nrog rau qhov me me li ob peb microns, ua rau lawv haum rau cov ntawv thov siab.
CNC kuj tseem rov ua tau zoo heev, txhais tau hais tias cov khoom zoo tib yam tuaj yeem tsim tau ntau dua thiab tsis muaj qhov sib txawv me ntsis. Qhov no ua rau CNC zoo tagnrho rau kev tsim khoom loj thiab kev tswj xyuas zoo.
Tsis tas li ntawd, CNC tuaj yeem txo cov sijhawm tsim khoom thiab cov nqi ua haujlwm. Nrog CNC, qhov chaw tuaj yeem tsim tau sai dua thiab muaj kev cuam tshuam tib neeg tsawg, txo cov sijhawm thiab kev ua haujlwm yuav tsum tau ua kom tiav cov khoom tiav.
Xaus
CNC tau hloov pauv kev lag luam kev lag luam los ntawm kev tso cai rau kev tsim cov khoom nyuaj nrog kev ua siab ntev thiab kev tswj xyuas zoo. Kev nce qib hauv kev suav thiab kev tsim kho software tau ua rau CNC ntau pheej yig dua thiab siv tau rau cov tuam txhab me me, txuas ntxiv nthuav dav thiab cuam tshuam.
Raws li kev siv thev naus laus zis txuas ntxiv mus, nws zoo li CNC yuav dhau los ua ntau yam thiab ntau yam, ua rau txoj hauv kev rau kev siv tshiab thiab kev tsim kho tshiab hauv kev tsim khoom.
