Analysis of Feed-Direction Burr Formation in Micro-Turning

Abstract:

A three-dimensional model of micro-turning using the finite element method (FEM) is created in this paper to analyzed the formation mechanism and influencing factors of feed-direction burr in micro-turning. According to the simulation and analysis result, in micro-turning,the deformation of the workpiece feed direction end is the combined action of the plastic bending deformation and shear slip deformation, and plastic bending deformation influences burr height and shear slip deformation affects the burr root thickness. Meanwhile, due to the amount of material involved in different deformation actions is changed, compared with conventional scale cutting, the various influencing factors have significant differences effect on the size of burr.
