A study of burr formulation processes using the finite element method: part I
Article Abstract:
The four stages of burr formation mechanism, initiation, initial development, pivoting point, and final development are studied using the finite element method. Data on the mechanism in orthogonal cutting and a quantitative analysis of burr/breakout formation are presented.

A study of burr formation processes using the finite elelment method: the influences of exit angle, rake angle, and backup material on burr formation processes, part II
Article Abstract:
Results demonstrate that finite element method analysis contributes a valuble insight into the mechanism of burr formation during machining as influenced by workpiece exit angles, tool rake angles, and backup materials. Data indicate that the burr formation process increases with the increase in the exit angle.

Burr/breakout model development and experimental verification
Article Abstract:
A model for predicting burr/breakout formation in orthogonal cutting shows good predictions about the burr/breakout phenomenon. The model uses observations of burr formation during the SEM micro-machining tests. A negative deformation plane begins to form when the steady state chip formation ceases. Burr formation occurs due to plastic bending and shearing of the negative deformation plane, but crack propagation along the plane contributes to breakout. Burr/breakout formation is proportional to the depth of the cut.
