Abstract
A finite element model has been developed utilizing the commercial ANSYS software to determine the temperature distribution & heat affected zone in laser cutting of titanium alloy (Ti-6%Al-4%V).The main aim of this paper is to determine the temperature reached in the vicinity of the location where the laser interaction with the work piece material takes place. This model is based on Fourier law of heat conduction and Gaussian distribution of laser. Temperature dependent thermal and mechanical properties of material are assumed in this analysis. Result obtained are then analyzed and thermal effect is then understood for the effective control of the process.
