A method for manufacturing a cutting insert green body comprising the steps of: (i) providing a cutting insert green body tool-set (38, 238, 438) comprising top and bottom dies (40', 40") and top and bottom punches (60', 60") associated therewith, the top and bottom punches being slidably reciprocable relative to their associated top and bottom dies; each die comprising opposing die abutment faces (44', 44") and die mounting faces (42', 42") and a die inner peripheral surface extending therebetween (48', 48"), the die inner peripheral surface comprising an inner first peripheral surface (50', 50") extending from the die abutment face, an inner second peripheral surface (52', 52") extending from the inner first peripheral surface and converging inwardly to a die inner edge (54', 54"), and an inner third peripheral surface (56', 56") extending from the die inner edge to the die mounting face and forming a punch tunnel (58', 58"); each punch (60', 60") comprising opposing punch pressing and punch mounting faces (64', 64", 62', 62") with a punch peripheral surface (66', 66") extending therebetween and forming a punch edge (68', 68") at an intersection of the punch peripheral surface and the punch pressing face; (ii) adjusting the cutting insert green body tool set (38, 238, 438) to a closed position in which the die abutment faces of the top and bottom dies abut each other with the inner first and second peripheral surfaces of the top and bottom dies forming a die cavity, the bottom punch is located in the punch tunnel of the bottom die, and the top punch is external to the punch tunnel of the top die; (iii) filling the die cavity with a pre-determined amount of sinterable powder; (iv) moving the top punch into the punch tunnel of the top die. (v) compacting the sinterable powder by urging the punches through the respective punch tunnels towards each other to a compaction position, wherein the punch edge of the top punch and the die inner edge of the top die are contiguous, and the punch edge (68") of the bottom punch (60") and the die inner edge (54") of the bottom die (40") are contiguous, thereby forming the green body; (vi) moving the top die and punch away from the bottom die and punch to an open position, thereby enabling removal of the formed green body. (i) providing a cutting insert green body tool-set (38, 238, 438) comprising top and bottom dies (40', 40") and top and bottom punches (60', 60") associated therewith, the top and bottom punches being slidably reciprocable relative to their associated top and bottom dies; each die comprising opposing die abutment faces (44', 44") and die mounting faces (42', 42") and a die inner peripheral surface extending therebetween (48', 48"), the die inner peripheral surface comprising an inner first peripheral surface (50', 50") extending from the die abutment face, an inner second peripheral surface (52', 52") extending from the inner first peripheral surface and converging inwardly to a die inner edge (54', 54"), and an inner third peripheral surface (56', 56") extending from the die inner edge to the die mounting face and forming a punch tunnel (58', 58"); each punch (60', 60") comprising opposing punch pressing and punch mounting faces (64', 64", 62', 62") with a punch peripheral surface (66', 66") extending therebetween and forming a punch edge (68', 68") at an intersection of the punch peripheral surface and the punch pressing face; (ii) adjusting the cutting insert green body tool set (38, 238, 438) to a closed position in which the die abutment faces of the top and bottom dies abut each other with the inner first and second peripheral surfaces of the top and bottom dies forming a die cavity, the bottom punch is located in the punch tunnel of the bottom die, and the top punch is external to the punch tunnel of the top die; (iii) filling the die cavity with a pre-determined amount of sinterable powder; (iv) moving the top punch into the punch tunnel of the top die. (v) compacting the sinterable powder by urging the punches through the respective punch tunnels towards each other to a compaction position, wherein the punch edge of the top punch and the die inner edge of the top die are contiguous, and the punch edge (68") of the bottom punch (60") and the die inner edge (54") of the bottom die (40") are contiguous, thereby forming the green body; (vi) moving the top die and punch away from the bottom die and punch to an open position, thereby enabling removal of the formed green body.
