Artificial　intelligence　is　the　crystallization　of　human　intelligence　and　an　important　transformation　of　human　labor　tools.　In　the　future　development　process,　artificial　intelligence　will　become　a　new　and　high-quality　tool,　which　will　bring　great　value　to　mankind.　The　engraving　machine　numerical　control　(CNC)　system　is　an　automatic　tracking　system,　which　has　strong　practical　value.　According　to　the　characteristics　of　NURBS　interpolation　algorithm,　this　paper　designs　a　CNC　sculpture　control　system　based　on　NURBS　interpolation　algorithm,　and　improves　its　dynamic　characteristics　and　positioning　accuracy.　Through　the　system　performance　test　of　the　CNC　sculptor　designed　in　this　paper,　starting　from　the　stability　and　safety,　we　can　see　from　the　experimental　data　that　the　CNC　sculptor　designed　in　this　paper　has　high　stability　and　safety.　In　addition,　compared　with　the　time　spent　by　the　market　engraving　machine　and　the　CNC　engraving　machine　designed　in　this　paper,　it　takes　22　minutes　and　20　minutes　for　the　market　engraving　machine　and　the　CNC　engraving　machine　designed　in　this　paper　to　carve　one　wooden　plate　respectively.　To　sum　up,　the　CNC　sculpture　control　system　designed　in　this　paper　has　a　good　effect　and　is　worthy　of　further　promotion　and　application.　　©　2023　IEEE.
