A set of heat transfer model and an equation for cutting-curve have been developed by analyzing the mechanism of glass cutting with laser beam in this paper. The relationship between the limit- ed velocity and the laser power has been obtained via solving the curve equation, which shows the correlations of laser power, cutting speed, workpiece thickness, the kerr width, and thermo-physical properties. Later, the analytical results have been compared to the presented experimental data, which shows that the model is correct and universal in glass cutting with laser-beam.
