| Résumé | Free-form laser consolidation is a novel process that produces a functional part layer by layer directly from a CAD model. A laser beam is used to melt a controlled amount of injected powder on a base plate to deposit the first layer and on previous passes for the subsequent layers. As opposed to conventional machining processes, this computer-aided manufacturing (CAM) technology builds complete functional parts or features on an existing component by adding instead of removing material. In this paper, laser consolidation of CPM-9V tool steel will be described to produce cutting blades on low alloy steel base to manufacture rotary cutting dies. The laser consolidated (LC) CPM-9V cutting blades, as well as the bond between the LC blades and the base, are metallurgically sound, free of cracks or porosity. Experimental results show that the LC CPM-9V has excellent mechanical properties. Its average tensile and yield strengths are about 1315 MPa and 821 MPa, respectively. Pin-on disk wear tests demonstrate that the wear loss of the LC CPM-9V material is only about 1/3 compared to that of the heat treated D2 tool steel currently being used for making rotary cutting dies. In production test, the LC CPM-9V die has successfully cut more than 180,000 m of labels without the need of re-sharpening so far. |
