Optimization of industrial grinding processes using the Theory of Aggressiveness: case studies from real-world manufacturing Open
In the first 60 years of grinding research (1914–1974), various dimensionless parameters were introduced to account for the fundamental mechanics of an abrasive contact. Later, these parameters were superseded by various chip-thickness mod…

Analytical study on critical load and deformation of chip in high-pressure jet assisted machining Open
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 f…

On mechanics and monitoring of plunge-roll rotary dressing of grinding wheels Open
A study is made into the mechanics and monitoring of rotary plunge-roll dressing of grinding wheels using a roll with multi-layer diamonds contained in a hybrid, metal-ceramic bond. A fundamental relationship is obtained between grinding/d…

The effects of grit properties and dressing on grinding mechanics and wheel performance: Analytical assessment framework Open
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 p…

Mechanics of self-rotating double-disc grinding process Open
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-rotat…

Application of the dimensionless Aggressiveness number in abrasive processes Open
The chip thickness is often used to characterize abrasive processes, particularly grinding. Unfortunately, because of the seemingly random nature of the geometrically undefined cutting points and difficulty in estimating the cutting-point …

On geometry and kinematics of abrasive processes: The theory of aggressiveness Open
Due to the stochastic nature of the abrasive-tool topography, abrasive processes are difficult to model and quantify. In contrast, their macro geometry and kinematics are usually well defined and straightforwardly controlled on machine too…
