摘要：

Laser Assisted Machining (LAM) involves machining the workpiece after softening it with laser emitted heat. This paper includes the study of temperature distribution across depth of the workpiece. A finite element model of transient temperature distribution problem is developed. The variation of thermal properties of the Ti-6Al-4V titanium alloy is considered. The Gaussian beam profile of the laser spot is selected for analysis. The effect of various input parameters like spot radius, laser power and scanning speed is studied. The parametric studies showed that the temperature of the workpiece increases with laser power and decreases with increase in spot radius and scanning speed. (C) 2014 Published by Elsevier Ltd.
