Usinage

L'usinage est une famille de procédés de fabrication de pièces par enlèvement de copeaux. Le principe de l'usinage est d'enlever de la matière de façon à donner à la pièce brute la forme et les dimensions voulues, à l'aide d'une machine-outil. Par cette technique, on obtient des pièces d'une grande précision.

Quels sont les différents procédés d'usinage ?

Il existe plusieurs procédés d'usinage, notamment : • Les usinages par déformation : forgeage, thermoformage, pliage • Les usinages par découpage : découpe laser, oxycoupage, • et enfin les usinages par enlèvement de matière : tournage, fraisage, électroérosion.

Quelles sont les 4 opérations basiques d'usinage ?

On distingue 4 classes importantes en usinage traditionnel : - le tournage, - le fraisage, - le perçage-alésage-taraudage - la rectification.

Quelle est la différence entre le tournage le perçage et le fraisage ?

Le processus de perçage peut être comparé au tournage et au fraisage, mais à cette différence que les exigences au niveau de la formation et de l'évacuation des copeaux sont plus strictes pour le perçage. Plus le trou est profond, plus il est difficile de contrôler l'opération et d'évacuer les copeaux.
