Abstract

The development of an optimized discontinuous drilling process of Inconel 718 with reduced thermal loads is supported by a CFD simulation, whose application already resulted in improvements of coolant flow. To consider the heat flow from the chip formation into the tool and the fluid, the numerical model must be expanded by a FEM chip formation simulation. Thus, its modulation and results validated by experimental work on thermal and mechanical loads are presented and discussed. In the following, the export of an optimized number of process interruptions will be enabled in favor of heat-related tool wear due to temperature monitoring.
