In machining, particularly of difficult-to-machine materials, chip-breaking with the aim to avoid entangled chips represents an important issue. In contrast to the widely used obstacle-induced chip breaking (e.g., chip former on the rake face of the cutting insert), the use of the high-pressure jet ...

This paper introduces an analytical assessment framework for evaluating grinding wheel performance derived from the model of cutting and sliding grinding force components. Four new parameters are proposed based on wheel topography. These parameters are normalized through the aggressiveness number, w ...

Unlike most double-disc grinding processes, which use forced workpiece rotation, some double-disc processes rely on workpiece self-rotation driven by non-uniform shear forces resulting from partial wheel-workpiece coverage. This self-rotation is poorly understood, with workpiece angular frequency re ...
