Laser processing technology has become the first choice for micro texture processing due to its advantages of high efficiency, high automation and easy to control. In the processing, laser parameters are important factors that affecting the size parameters and morphology of micro texture. Laser technology was used to process micro texture on the surface of cemented carbide tool. The influence of laser power and scanning speed on the size and morphology of micro texture was analyzed and revealed, and the optimal parameters of micro texture processing were determined.
