•A virtual FE geometry DoE identified improved drill bit designs.•FE analysed operational stresses in forming tools to predict failure locations.•Shortcomings in material input parameters are highlighted.•Potential improvements in FE modelling techniques and input data are described.
This paper demonstrates the significant role of finite element (FE) simulation/modelling in the optimisation of cemented tungsten carbide drill bits and forming tools. Two case studies are presented, one from the development phase for a new product and the other from the continuous improvement process during mass production. Additionally, a number of important issues are raised concerning the material property data used for FE simulation, the interpretation of results generated, and approaches to bring FE a step closer to simulating real components and operating conditions with greater predictive accuracy regarding the failure probability of the component in service.
