Cutting tools with surface micro-textures have positive effects on reducing friction, improving the wear resistance and anti-adhesion. The comparative trials are carried out in fiber laser machining of micro-grooves and micro-holes on the rake face of cemented carbide cutting tool. The effects of various processing parameters on topography and quality of micro-textures are analyzed, such as average output power, pulse repetition rate, defocusing distance. The experimental results show that the width of micro-grooves and the diameter of micro-holes have an increasing and a decreasing tendency with the increase of the average output power and the pulse repetition rate respectively. Furthermore, the morphologies of micro-textures can be improved by the larger average output power and the pulse repetition rate. It is observed that bottom morphologies of the micro-grooves is more uniform and smoother when the defocusing distance ranges from -1~-1.4 mm.
