Abstract:
In this paper, according
to the theory of brittle fracture and applying the Boundary Element
Method the stress field and the propagating path of crack in the outing
zone of glass cutting are calculated, and then two cutting models, one
for large undeformed chip thickness and another for small punde formed
chip thickness, have been constructed. These two models re verified by
experimental results. Based on these two models the following topics are
discussed and explained: The mechanism of the formation of various
categories of chip; The mechanism of the formation of machined surface;
The relation between the chip appearance and the machined surface
roughness, cutting force, and the wear of outing tool.
Key words:

Cutting Surface roughness
