Beschreibung

Tool wear during hard machining leads to unfavourable changes of the workpiece surface and subsurface layers. Due to increasing flank wear, thermal and mechanical loads affect the microstructure and the residual stress state of the workpiece subsurface. These effects cause a reduction of the lifetime of the machined components during operation. This article presents an approach of modified corner radii of cutting tools for hard turning processes to change the tool wear progression and the influence on the machined subsurface layers. Hereby the size and direction of the contact length of the cutting edge is adjusted as well as the specific load during machining. The results show the potential of controlling the tool wear and the workpiece subsurface properties by the contact conditions of the tool-workpiece interface during hard turning.
