Abstract: A threading insert includes a top surface, an opposite bottom surface, a side surface connecting the top surface and the bottom surface, and a first tooth. The first tooth has a first cutting edge, the first cutting edge including a first top cutting edge connecting a first leading cutting edge and a first trailing cutting edge. The first cutting edge has an edge roundness and the size of the edge roundness varies along the first cutting edge.

Abstract: The disclosure relates to a method of manufacturing a cutting tool including the steps of: providing a cutting tool blank including a cutting edge, defined by a cross-sectional wedge angle (β). The wedge angle has a variation along the cutting edge, and material is removed from the cutting edge with a constant material removal rate per length unit of the edge, such as to form a corresponding variation of edge rounding along the cutting edge. The disclosure further relates to a cutting tool including the cutting edge defined by the cross-sectional wedge angle having a variation along the cutting edge and wherein the cutting edge has a corresponding variation of edge rounding along the cutting edge.
Abstract translation: 本公开涉及一种制造切割工具的方法，包括以下步骤：提供包括由横截面楔角（＆bgr）限定的切割边缘的切割工具坯料。 楔形角度沿着切割边缘具有变化，并且材料以切割边缘的每个长度单位的恒定的材料去除速率从切割边缘移除，以形成沿着切割边缘的边缘四舍五入的相应变化。 本发明还涉及一种切削工具，其包括由沿着切削刃具有变化的横截面楔角限定的切削刃，并且其中切削刃具有沿着切削刃的边缘相应变化。
