Effect of cutting conditions on temperature generated in drilling process: a FEA approach
journal contribution
posted on 2011-04-14, 10:33 authored by Riaz Muhammad, Naseer Ahmed, Y.M. Shariff, Vadim SilberschmidtVadim SilberschmidtHeat generated during a drilling process has a major influence on the tool life and the
workpiece material behaviour that are significantly affected by cutting conditions (cutting
speed, feed rate). In this paper, the effect of cutting conditions on temperature
generated in drilling process is investigated by means of finite element (FE) simulations
using commercially available code MSC MARC MENTAT. A Johnson Cook material
model is used to describe elasto-plastic deformation behaviour. The updated Lagrangian
procedure is used to implement the transient analysis for the elasto-plastic material
in the model. A modified shear friction model is employed to model friction at the
tool tip-workpiece interface. The effect of friction on chip shape is investigated with FE
simulations. Experiments were carried out to verify the FE results.
