Material Removal Phases in Single Abrasive Grain Grinding

Keywords: Grinding, finite element method, simulation, single grit INTRODUCTION Grinding is a material removal process by arbitrarily bounded abrasive grits on the wheel periphery. These abrasive grits do not have certainly defined geometric shape for their cutting edges. Therefore, grinding is not well-defined process compared to other machining processes. In order to obtain good quality of ...
