Coated solid carbide end mills are used, among other things, in mechanical engineering and the automotive industry. Despite the extensive and intensive use of these milling tools, the level of knowledge about the effects of the production-related surface and edge zone properties of solid carbide end mills on their performance is low. In addition, the interrelationships and interactions of the respective manufacturing processes along the process chain for manufacturing these tools are insufficiently known. Since the production-related tool properties of the milling cutters are not optimally matched with regard to their application behavior, the performance potential of the cutting material has not yet been exhausted.
The aim of the project is to create a knowledge base for the production of high-performance milling cutters whose application behaviour exceeds that of conventionally produced milling cutters by methodical research into the influence of the production-related surface and edge zone properties of coated solid carbide milling cutters on their functional behaviour and their development along the process chain. In order to achieve the project objective, different surface and edge zone properties of the tools will be generated by varying the manufacturing processes in the process sequence and the development of the production-related tool properties along the process chains will be analysed. The tool properties will then be investigated with regard to their influence on the milling cutter application behaviour. Based on the results of the tool life investigations and the findings from the analysis of the production history, design approaches for an optimized production process sequence for the manufacture of solid carbide end mills are then derived.
