\"Usinage<\/p>\n

Pour commencer simplement\u00a0:<\/span><\/span>Usinage CNC<\/span><\/span><\/strong>\uff08Usinage \u00e0 commande num\u00e9rique par ordinateur) est une m\u00e9thode qui utilise des<\/span><\/span>machines \u00e0 commande num\u00e9rique<\/span><\/span><\/strong>plut\u00f4t que des outils manuels pour couper et fa\u00e7onner des mat\u00e9riaux solides.<\/span><\/span><\/p>\n

L\u2019essence m\u00eame du CNC consiste \u00e0 prendre une conception num\u00e9rique et \u00e0 la transformer en pi\u00e8ces physiques avec une grande pr\u00e9cision et une reproductibilit\u00e9 \u00e9lev\u00e9e. Je compte sur le CNC au quotidien pour fournir \u00e0 mes clients qui ont besoin de pr\u00e9cision et de rapidit\u00e9 des<\/span><\/span>pi\u00e8ces usin\u00e9es sur mesure<\/span><\/span><\/strong>, des prototypes et une production en petites s\u00e9ries.<\/span><\/span><\/p>\n

D\u00e9finition et r\u00f4le essentiels dans la fabrication moderne<\/span><\/span><\/h3>\n

En r\u00e9sum\u00e9\u00a0:<\/span><\/span><\/p>\n

    \n
  • CNC = Ordinateur + Machine-outil + Mouvement programm\u00e9<\/span><\/span><\/strong><\/li>\n
  • L\u2019ordinateur lit un<\/span><\/span>fichier de code<\/span><\/span><\/strong>\uff08code\u00a0G), puis contr\u00f4le les moteurs de la machine pour d\u00e9placer les outils de coupe.<\/span><\/span><\/li>\n
  • Le r\u00e9sultat\u00a0:<\/span>des pi\u00e8ces pr\u00e9cises et reproductibles<\/span><\/span>fabriqu\u00e9es \u00e0 partir de m\u00e9tal, de plastique, de bois, etc.<\/span><\/span><\/strong><\/li>\n<\/ul>\n

    L'usinage CNC en tant que proc\u00e9d\u00e9 cl\u00e9 de la fabrication moderne, adapt\u00e9 \u00e0 :<\/span><\/span><\/p>\n

      \n
    • Prototypage<\/span><\/span><\/strong>\u2014Obtenir rapidement des pi\u00e8ces fonctionnelles<\/span><\/span><\/li>\n
    • pi\u00e8ces sur mesure<\/span><\/span><\/strong>\u2014Composants \u00e0 usage unique ou en petites s\u00e9ries<\/span><\/span><\/li>\n
    • Production de haute pr\u00e9cision<\/span><\/span><\/strong>\u2014Pi\u00e8ces n\u00e9cessitant un ajustement et un fonctionnement pr\u00e9cis \u00e0 chaque fois<\/span><\/span><\/li>\n<\/ul>\n

      Les fabricants du monde entier utilisent l'usinage CNC car il :<\/span><\/span><\/p>\n

        La fabrication par enl\u00e8vement de mati\u00e8re et d'autres m\u00e9thodes<\/span><\/span><\/h3>\n

        L'usinage CNC est une<\/span><\/span>technique de fabrication par enl\u00e8vement de mati\u00e8re<\/span><\/span><\/strong>Ce qui signifie :<\/span><\/span><\/p>\n

          \n
        • Nous<\/span><\/span>partons d'un bloc solide<\/span><\/span><\/strong>(m\u00e9tal, plastique, etc.)<\/span><\/span><\/li>\n
        • Machine<\/span>Utilisation d'outils de coupe<\/span><\/span>Retirer le mat\u00e9riau<\/span><\/span><\/strong><\/li>\n
        • Nous \u00e9liminons<\/span><\/span><\/strong>les \u00e9l\u00e9ments inutiles<\/span>pour obtenir la forme finale<\/span><\/span><\/li>\n<\/ul>\n
