FINITE ELEMENT MODELING OF BURR FORMATION IN METAL CUTTING

Burr Formation in Fly-cutting

Micro-groove is one of the most important features in mechanical, electronic, photonic, and bio-medical components. In recent years, fabircation of micro-grooves became increasingly important with an advancement of product miniaturisation. It is realised that in micro-machining of grooves, the principal problem is the presence of burrs along the feature edges and also the profile inaccuracy aff...

Chip Formation Process using Finite Element Simulation “Influence of Cutting Speed Variation”

The main aim of this paper is to study the material removal phenomenon using the finite element method (FEM) analysis for orthogonal cutting, and the impact of cutting speed variation on the chip formation, stress and plastic deformation. We have explored different constitutive models describing the tool-workpiece interaction. The Johnson-Cook constitutive model with damage initiation and damag...

Continuous chip formation in metal cutting processes using the Particle Finite Element Method (PFEM)

This paper presents a study on the metal cutting simulation with a particular numerical technique, the Particle Finite Element Method (PFEM) with a new modified time integration algorithm and incorporating a contact algorithm capability . The goal is to reproduce the formation of continuous chip in orthogonal machining. The paper tells how metal cutting processes can be modelled with the PFEM a...
