A method of compacting a powder into a cutting insert green body, such that said cutting insert green body obtains a barrel-shape having a parting line on the outer peripheral surface thereof which is at least partially non-perpendicular to a pressing axis (x) along which said compacting is performed, said method comprising the steps of: - providing a compaction tool comprising a die (18, 40) that comprises an upper die part (19, 41) and a lower die part, and an upper punch and a lower punch, wherein the upper and lower die parts (19, 20; 41, 20), when joined together, contribute to defining a die cavity that is delimited by an inner peripheral surface that defines the shape of the outer peripheral surface of the barrel-shaped green body to be formed by said compaction, said method further comprising the steps of - providing at least one of the lower die part and the upper die part (19, 41) with a pressing bore extending from said die cavity, for the lower punch or the upper punch to be received in in connection to said compacting, - said method being characterized in that it comprises the steps of - providing the lower die part with an upper inner edge that extends along a line defining the parting line of the green body, - providing the upper die part (19, 41) with a lower inner edge that extends along a line defining the parting line of the green body, - providing the upper die part (19, 41) with an upper surface that, at least in one direction, extends rectilinearly, - providing the upper die part (19, 41) with an upper opening in said upper surface, through which the upper punch is enabled to be forwarded to said cavity, - positioning the upper die part (19, 41) above the lower die part such that the lower inner edge of the upper die part (19, 41) is contiguously arranged in relation to the upper inner edge of the lower die part, - positioning the upper punch in a retracted position relative the upper opening of the upper die part (19, 41), - filling powder into the die through said upper opening in the upper surface of the upper die part (19, 41), - compacting the powder by forwarding at least the upper punch towards said cavity, - retracting the upper punch, - exposing the green body by retracting the upper die part (19, 41) from the lower die part. - providing a compaction tool comprising a die (18, 40) that comprises an upper die part (19, 41) and a lower die part, and an upper punch and a lower punch, wherein the upper and lower die parts (19, 20; 41, 20), when joined together, contribute to defining a die cavity that is delimited by an inner peripheral surface that defines the shape of the outer peripheral surface of the barrel-shaped green body to be formed by said compaction, said method further comprising the steps of - providing at least one of the lower die part and the upper die part (19, 41) with a pressing bore extending from said die cavity, for the lower punch or the upper punch to be received in in connection to said compacting, - said method being characterized in that it comprises the steps of - providing the lower die part with an upper inner edge that extends along a line defining the parting line of the green body, - providing the upper die part (19, 41) with a lower inner edge that extends along a line defining the parting line of the green body, - providing the upper die part (19, 41) with an upper surface that, at least in one direction, extends rectilinearly, - providing the upper die part (19, 41) with an upper opening in said upper surface, through which the upper punch is enabled to be forwarded to said cavity, - positioning the upper die part (19, 41) above the lower die part such that the lower inner edge of the upper die part (19, 41) is contiguously arranged in relation to the upper inner edge of the lower die part, - positioning the upper punch in a retracted position relative the upper opening of the upper die part (19, 41), - filling powder into the die through said upper opening in the upper surface of the upper die part (19, 41), - compacting the powder by forwarding at least the upper punch towards said cavity, - retracting the upper punch, - exposing the green body by retracting the upper die part (19, 41) from the lower die part.
