Abstract:
The machining of safety-critical components, e.g. turbine disks and blades, is expected to meet highest demands regarding functionality and quality. At the same time, a fast and affordable process design for the production is a major driver for the economic development of these components. Effective increase in productivity requires in addition to the development of machining technologies, new approaches in process design and planning. The integration of simulation into computer aided design of multi-axis processes provides a great potential for further optimisation of the processes. By using the macro simulation model introduced in this paper, the computational complexity to gain relevant process information is reduced and hence made accessible more easily. Through the presented macro simulation, detailed tool-workpiece engagement is calculated which co-relates to mechanical and thermal stresses on the tool. Based on the calculations the process can be designed by reducing the tool
load in the course of the process. This way, the tool life of the used milling cutters can be significantly increased resulting in an increase of process robustness and efficiency, thereby reducing used resources.
