Method for preparing micro nano composite texturing cutting tool by using femtosecond laser
The invention relates to the technical field of micro structural surface preparation and laser micro processing, and in particular provides a method for preparing a micro nano composite texturing cutting tool by using femtosecond laser. In the method, micro nano texturing and micro/nano composite texturing preparation is performed on the cutting tool surface by utilizing the unique interaction property between femtosecond laser and materials, the operation is simple, and the accuracy can be controlled. The preparation of micro/nano composite texture can be performed on a coated cutting tool by adopting a coated surface direct texturing method or a two step composite texturing method. The method overcomes the defect of singleness of texturing only in micron scale in the conventional cutting tool texturing technology, and can further improve the abrasion resistance of the cutting tool, and prolong the service life of the cutting tool.
