Title (EN) CUTTING INSERT FOR A MILLING TOOL
(FR) INSERT DE COUPE POUR UN OUTIL DE FRAISAGE
Abstract:
(EN) A milling tool includes a cutting insert coupled to a blade. The blade may change from a retracted to an expanded state to engage and cut downhole casing. The cutting insert may include a semi-elliptical body having major and minor diameters. The length may be about equal to half a minor diameter of the semi-elliptical body, and the width may be greater than 85% of the major diameter of the semi-elliptical body. A front cutting edge may follow an elliptical curve. One or more back-up cutting edges or chip-breakers may also follow elliptical curves. The milling tool may include multiple blades. One or more of the blades may have different arrangements of cutting inserts. Different arrangements may include varying the position of similar cutting inserts or using different types/geometries of cutting inserts on different blades.
(FR) Un outil de fraisage comprend un insert de coupe associé à une lame. La lame peut passer d'un état rétracté à un état étendu pour venir en prise avec le cuvelage de fond de trou et couper celui-ci. L'insert de coupe peut comprendre un corps semi-elliptique ayant des petit et grand diamètres. La longueur peut être environ égale à la moitié d'un petit diamètre du corps semi-elliptique, et la largeur peut être supérieure à 85 % du grand diamètre du corps semi-elliptique. Un bord coupant avant peut suivre une courbe elliptique. Un ou plusieurs bords coupants ou brise-copeaux peuvent également suivre des courbes elliptiques. L'outil de fraisage peut comprendre de multiples lames. Une ou plusieurs des lames peuvent avoir différents agencements d'inserts de coupe. Les différents agencements peuvent comprendre la variation de la position d'inserts de coupe similaires ou l'utilisation de différents types/géométries d'inserts de coupe sur différentes lames.
