Preparation of symmetrical and asymmetrical cutting edges on solid cutting tools using brushing tools with filament-integrated diamond grits

The manufacturing of asymmetric cutting edges is crucial for tool life and performance of cutting tools. For rotationally symmetric cutting tools with a complex profile of the cutting edges, such as milling or drilling tools, no suitable preparation methods exist so far. This paper presents a model that describes the targeted preparation of symmetrical and asymmetrical cutting edges using abrasive brushing tools with filament-integrated diamond grits in dependence of various process parameters. The selected process parameters and dimensions of the brushing tool ensure the accessibility of real cutting tools. In addition, the results of investigations on brushing tool wear are presented.
