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.

摘要： A method for manufacturing a cutting insert green body from a sinterable powder, a tool set for manufacturing the cutting insert green body by that method and the green body manufactured by the tool set. The tool set has axially moving upper and lower punches and radially moving side punches. The side punches move slidably on die rods. The side punches and die rods move in channels in a base body on which a cover plate is mounted. The upper and lower punches move in through holes in the cover plate and base body, respectively. The die rods are stationary during compaction of the sinterable powder. The upper, lower and side punches form surfaces of the green body and the die rods form some of the edges of the green body. The green body can have undercuts and the edges formed by the die rods can be non-linear in shape.

摘要： A cutting insert for retention in a rotating cutting tool having an axis of rotation has two opposing end surfaces and a peripheral surface extending therebetween, each end surface having a mutual first axis of symmetry passing through the end surfaces about which each end surface has N-fold rotational symmetry for some value of N where N is chosen from the group consisting of 2, 3 and 4. A peripheral cutting edge is formed at the junction between each end surface and the peripheral surface, the peripheral cutting edge having N curved cutting edges merging with N straight cutting edges which extend between the curved cutting edges at extremities thereof. The curved cutting edges of the two end surfaces are not aligned in an end view of the cutting insert along the first axis of symmetry.
