Abstract: The conditions of conversion
from brittle removal mechanism to plastic removal mechanism are
studied through analysis of ceramic microstructure and the
relationship between the material removal form and machining
unit. By the rational technology program worked out, the plane
and cylindrical mirror-like surface machining is successfully
achieved and its surface roughness Ra is 0.01～0.03μm after many
times of experimental study.
Key words:
