1. A micro-nano incremental mechanical surface treatment method, comprising the following steps:
(1) using an end of a modification tool to contact a surface of a substrate material, and presetting moving parameters of the modification tool by means of 3D modeling software;
(2) rotating the modification tool in a local region of the surface of the substrate material, and moving the modification tool according to preset moving parameters in step (1) to compress the surface of the substrate material;
(3) after the modification tool has processed the entire surface of the substrate material, enabling the modification tool to move downwards to the indented surface compressed previously; and
(4) repeating step (2) and step (3) until the substrate material is compressed to a preset thickness:
wherein the moving parameters in step (1) comprise a moving path, a tool rotating speed, a feeding speed, a single-layer downward compressing amount, a processing pass and a secondary feeding overlapping rate;
wherein the moving path is a unidirectional, a reciprocating, a lattice, or a spiral, the tool rotating speed is in a range of 1000 rpm to 30000 rpm, the feeding speed is in a range of 1000 mm/min to 6000 mm/min, the single-layer downward compressing amount is in a range of 0.01 mm to 0.1 mm, the processing pass is in a range of 10 times to 30 times, and the secondary feeding overlapping rate is in a range of 2% to 10%.
