Milling cutter having undulating chip breaker |
摘要 |
A cutting element includes a front face and leading face extending between a first and second sides. A leading cutting edge is located at an intersection of the front face and the leading face, and an undulating back-up cutting edge is formed in the front face and extends from the first side to the second side, and defines a leading surface and a trailing surface. A method includes cutting with a tool having a blade coupled to a tool body, and a cutting element coupled to a forward surface of the blade. The cutting element has a leading cutting edge formed at an intersection of front and leading faces, and an undulating back-up cutting edge formed in the front face and defining leading and trailing surfaces. The leading cutting edge of the cutting element contacts and cuts a work piece. |
