| 摘要 |
A single-sided tangential ramping milling insert for high speed milling includes opposite insert seating and top surfaces and a peripheral surface which extends therebetween. The milling insert has a reference plane (P) which passes through the entire peripheral surface, midway between the seating and top surfaces. The peripheral surface includes two opposite side surfaces. Each side surface includes a first cutting edge, a second cutting edge connected to the first cutting edge and extending transversely thereto, a ramping cutting edge connected to the second cutting edge and located opposite the first cutting edge, and a rake surface which extends from at least a portion of the first cutting edge toward the insert seating surface. The milling insert includes two ramping relief surfaces, each of which extends from a ramping cutting edge of one side surface towards the first cutting edge of the opposite side surface. |

1. A single-sided tangential ramping milling insert (14) for high speed milling comprising opposite insert seating and top surfaces (20, 22), and a peripheral surface (24) extending therebetween, the milling insert (14) having a reference plane (P) passing through the entire peripheral surface (24), midway between the seating and top surfaces (20, 22),
the peripheral surface (24) comprising two opposite side surfaces (26) having a first axis (X) passing midway therebetween and lying in the reference plane (P), each side surface (26) comprising: a first cutting edge (40) formed at an intersection of the side surface (26) and the insert top surface (22), a second cutting edge (42) connected to the first cutting edge (40) and extending transversely thereto, a ramping cutting edge (44) connected to the second edge (42) and located opposite the first cutting edge (40), and a rake surface (38) extending from at least a portion of the first cutting edge (40) towards the insert seating surface (20),
wherein the milling insert (14) comprises two ramping relief surfaces (60), each of which extends from the ramping cutting edge (44) of one side surface (26) towards the first cutting edge (40) of the opposite side surface (26). |
