Title (EN) DIAMOND TABLE ON NON-PLANAR CUTTING ELEMENTS
(FR) PLAQUE EN DIAMANT SUR DES ÉLÉMENTS DE COUPE NON PLANS
Abstract:
(EN) A cutting element includes a pointed region having a side surface extending from a pointed region outer perimeter to a peak, an ultrahard material body forming a portion of the pointed region including the peak, and a base region extending a depth from the pointed region outer perimeter. The ultrahard material body has a height to width aspect ratio of greater than 3/4, the height defined between two points of the ultrahard material body having the greatest distance apart along a dimension parallel with a longitudinal axis of the cutting element, and the width defined between two points of the ultrahard material body having the greatest distance apart along a dimension perpendicular to the longitudinal axis.
(FR) La présente invention concerne un élément de coupe qui comprend une région pointue qui présente une surface latérale qui s'étend d'un périmètre extérieur de zone pointue à une crête, un corps de matériau ultradur qui forme une partie de la région pointue y compris la crête, et une région de base qui s'étend sur une profondeur à partir du périmètre extérieur de région pointue. Le corps de matériau ultradur présente un rapport hauteur/largeur supérieur à 3/4, la hauteur définie entre deux points du corps de matériau ultradur présentant la plus grande distance d'éloignement le long d'une dimension parallèle à un axe longitudinal de l'élément de coupe, et la largeur définie entre deux points du corps de matériau ultradur présentant la plus grande distance d'éloignement le long d'une dimension perpendiculaire à l'axe longitudinal.
