CNC machining yog rooted nyob rau hauv technologies kev nce qib thaum lub sij hawm Industrial Revolution nyob rau hauv nruab nrab -19th caug xyoo, thaum cov tuam txhab tsim khoom pib siv cam-based lathes thiab milling cov cuab yeej hauv kev tsim phom loj, cov khoom siv hauv tsev thiab cov khoom siv niaj hnub. Los ntawm 1940s thiab '50s, rudimentary numerical control machining nyob rau hauv daim ntawv ntawm m-code punch phaib pib automate ob peb txoj haujlwm tsim khoom uas tau pib tswj los ntawm pab pawg neeg ua haujlwm.
Raws li cov khoos phis tawj digital thiab khoos phis tawj tau txhim kho nyob rau xyoo 1970 thiab 80s, ntau cov cuab yeej tsim khoom tuaj yeem siv tau los txhim kho kev tsim khoom nrawm thiab kev ua haujlwm tag nrho.
Tam sim no nyob rau hauv lub xyoo pua 21st, CAM thiab CAD software thiab txiav-ntug CNC tshuab tso cai rau pawg me me tsim cov tswv yim zoo rau kev tsim cov khoom loj ntawm cov khoom. Raws li kev kawm tshuab thiab kev txawj ntse txawj ntse txuas ntxiv mus, kev lag luam kev lag luam yuav zoo li txuas ntxiv txhim kho thiab ua haujlwm zoo.
