Abstract

The invention discloses a method for designing a composite micro-texturing guide rail. In the invention, orderly distributed composite micro textures are initiatively processed on a working surface of the guide rail by laser, and the geometrical parameters of the composite micro textures that diameters d of recesses are equal to 100 microns to 500 microns, depths h of the recesses are equal to 1 micron to 50 microns, diameters D of raised shoulders are equal to 50 microns to 450 microns, heights H of the raised shoulders are equal to 1 micron to 70 microns, and diameters of micro bump texture flat tops are equal to 5 micron to 550 microns, area ratio is 15%-65% and interval S is equal to 200 microns to1500 microns. According to the invention, dynamic friction and static friction on surface of the guide rail can be balanced, creeping phenomenon can be inhibited effectively, service life is prolonged obviously, and stability and machining quality are improved.
