Advances in modeling of fixed-abrasive processes

Research over the last 70 years has led to a better understanding of fixed-abrasive machining processes. This knowledge is often expressed in the form of physical and empirical models that cover forces, power, specific energy, wheel/workpiece topography, wear, thermal aspects, cooling, dressing, and more. This paper first examines the established models that continue to constitute the fundamental knowledge base in fixed-abrasive technology. Special attention is given to geometry, kinematics, and thermomechanical modeling. Recent advances in process monitoring and big data analytics provide new opportunities to further strengthen the state of the art in modeling through data-driven approaches. In addition, examples on how models – implemented in simulation software – can be used to predict and optimize industrial operations have been demonstrated. This is illustrated by several use cases from real production, including bearing, creep-feed form, gear, camshaft, crankshaft, and centerless grinding, along with diamond-wheel truing.
