Study on laser deep hole drilling

Now the laser drilling is a useful technique in industry products.A very important problem is how to obtain the high quality deep hole drilling.Starting from the selection of laser parameters and the instantaneous energy balance in the gasification and melting process,the engineering design of deep hole drilling was presented,in this paper,and pointed the selection of ratio of depth and diameter,the design of the laser pulse shape.The calculation results are close to the experimental data.
