Abstract
The
drilling burr formation was simulated based on the model in Part I and the results were
compared with proposed mechanism and high-speed video images. The burr formation
mechanism was divided into five stages: steady-state cutting, burr initiation,
development, initial fracture, and final burr formation. The differences in the burr
formation mechanism between a uniform burr and a crown burr were observed at burr
initiation stage and initial fracture stage. Burr size can be estimated from the
measurement of the initiation thickness.
