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.
