Additive Manufacturing of application optimized tungsten carbide precision tools
Abstract
The joint research project PraeziGen is dedicated to overcome today’s limits of tool making by applying additive manufacturing (AM), respectively selective laser melting (SLM), to fabricate application optimized carbide precision tools with complex inner and outer shape. A main objective is the development of a process chain for AM of near-netshape cutting tools and the qualification of tungsten carbide for the SLM process. This paper focuses on the scientific fundamentals of the process and different approaches, which are followed to avoid the formation of pores, cracks and brittle material phases inside the generated samples. The sintered samples are evaluated by means of metallographic analyses in order to optimize the process parameters. Tool samples are manufactured with optimized sintering strategies and further processed to cutting inserts. The finished inserts are evaluated within a turning process.
