Abstract
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.
