Automated Laser Fabrication is an emerging advanced technology which penetrating in different aspects of manufacturing. This paper reports the automation laser fabrication of low-cost diamond tools. The engineered composition of the diamond and Cu-Sn-Ti are selected to address the issues, like- dissociation of diamond particles in metal matrix, good substrate-clad bonding etc. to ensure crack-free and pore-free deposition.
The initial experiments pre-placed experiments show a promising trend. The process parameters are being optimized to obtain desired mechanical properties (like- hardness, wear resistance, toughness etc.) with sound metallurgical bonding. The paper will describe the optimization of process parameters along with material characterization.
