Abstract:
In industrial practice, the machining of lightweight profiles is associated with problems. During conventional machining operations, process stability is often affected by material-dependent adhesion at the cutting edges. Due to adhesion, the quality of surfaces and bore-holes as well as the reliability of the machining operation often become inadequate. The correct machining of thin-walled profiles is exceptionally difficult due to their elastic structure and their tendency to oscillate in the frame structure. During the machining of extruded steel wire reinforced light-metal-matrix profiles, tool wear is an additional crucial factor. The potentials and limitations of process design for high quality bore-holes produced by drilling and circular milling of conventional and steel-wire reinforced aluminium profiles are shown in the following article. Both, experimental research and simulation-based analyses form the basis of this paper.
