CNC tig yog txheej txheem hlau fabrication uas koom nrog ib feem nyob rau hauv qhov chaw ntawm ib tug rotating spindle uas ua rau kev sib cuag nrog ib tug nyob ruaj ruaj cuab tam kom tshem tawm cov khoom kom txog rau thaum ib feem yog qhov xav tau.
Lub ntsiab kom zoo dua ntawm CNC tig yog tias nws tuaj yeem tsim cov geometry nyuaj uas yuav tsis tuaj yeem tsim hauv CNC mills. Qhov no yog qhov tseeb tshwj xeeb tshaj yog rau cylindrical qhov chaw lossis "wavy" nta, uas yuav nyuaj heev rau kev tsim ntawm CNC zeb lwm yam. Qhov no tsis yog hais tias CNC tig tuaj yeem tsim qhov sib npaug; lub tshuab dhos tuaj yeem tsim ntau hom geometry, nrog rau cov duab square thiab hexagonal.
