Abstract

A compacting device and a method for producing a cutting insert green body by compacting a powder is provided. A die contributes to defining a die cavity that defines the shape of the green body to be formed. The die includes an upper die part defining an upper part of said die cavity together with an upper punch, a lower die part defining a lower part of the die cavity together with a lower punch, and intermediary die members, which are moveable in a plane perpendicular to a pressing axis and which define an intermediary part of the die cavity. The intermediary part of the die cavity defines an undercut portion, which extends circumferentially around the green body to be formed and which includes three or more peripheral indexing grooves in the green body.
