N2 - Grinding should not only generate a shape as close as possible to the final geometry to reduce the difficulty for final figuring, but also to minimize the thickness of the relief layer. Computer simulation will help us understand and achieve these purposes. In this paper, real time simulation of loose abrasive grinding is considered.
Abrasive fine-finishing technology utilizes a pressure-copying principle as the material removal process (The stock removal capability of the abrasive fine-finishing is far lower than grinding, and it is limited to controlling dimensional accuracies, such as sizes, taper, roundness etc.).
