Grinding Process Size Effect and Kinematics Numerical ...

The present work developed numerical codes that simulate steady-state grinding process kinematics. The three-dimensional modeling procedure entails the following: specifying the sizes, shapes, and positions of individual abrasive grains on the wheel surface; geometrically calculating the abrasive grains' depth of cut distributions along the grinding zone as they pass through the …
