深孔激光加工研究

Study on laser deep hole drilling

研究了深孔形成的物理过程，提出了一种新型的深孔加工的激光脉冲波形，用光锥方程和能量平衡关系式推导出孔深、孔径及有关激光参数，与实验结果基本相符。

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.
