Preparation of laser micro-textured broach and residual energy

Abstract

Based on the fact that surface textured cutting tool can effectively improve the cutting performance, taking broach material into consideration a processing method of micro-textured broach was put forward. Laser processing technology was used to generate a micro-texture on the flank of broach, and the influence of various processing parameters was researched. The influence of Q frequency, power, scanning speed and processing times on the texture formation and wetting was investigated. The experimental results show that with the increase of the Q frequency, the texture boundaries are more clear, recast area will be larger with the increase of power, the depth of micro texture is proportional to the processing times, and the scanning speed has to be lower than a certain speed to remove material adequately. In the initial stage of the preparation, the energy remains on the surface of the texture will make the hydrophobic texture appear hydrophilic.
