Investigation of Micro Holes Fabricated by Femtosecond Laser on S136

Article Preview

Abstract:

Femtosecond laser is now widely used in micro holes drilling because of its unique advantages, such as high efficiency, high precision and non-contact. Femtosecond laser is the best choice to fabricate micro holes. This paper makes a systematic study of the influence of laser power and number of pulses on diameter and depth of micro holes on S136 die steel through the focusing lens with focal length of 35 cm. A series of high-precision micro holes with different diameter and depth are fabricated. The relationship between the dimension of fabricated micro holes and the process parameters is determined.
