Formation of Cutting Direction Burr/Fracture in Orthogonal Cutting

Abstract:

Cutting direction burr/fracture is one of the important factors that influence the edge quality and performance of precision parts. A finite element model based on material failure mode is developed in this study to simulate the burr /fracture forming process. According to workpiece materials deformation and mechanical properties from the simulation results, the cutting direction burr/fracture formation process is analyzed. The cutting direction burr forms when there is a crack in the area near the tool tip and grow along the principal shear zone, the cutting direction fracture forms as the crack grow along negative zone.
