Abstract
Abstract
Laser drilling is of great significance for metal parts production, aerospace parts processing, precision chip manufacturing, etc. In recent years, drilling technology based on new laser devices has become an international research hotspot for its advantages of high speed, high accuracy and low thermal damage. In this paper, the laser drilling is compared with other drilling methods, and the influencing factors and application trends are introduced. At the same time paper introduced the main research on the model and theory of laser drilling at home and abroad. The important effects of thermal effect and molten material on drilling and the latest research progress are introduced.
