METHOD FOR OBTAINING ARTIFICIAL ROUGHNESS ON THE SURFACE OF PART BY MECHANICAL PROCESSING Russian patent published in 2021 - IPC B23C1/00 B21C37/15 F28F1/00 

FIELD: mechanical engineering.

SUBSTANCE: The invention relates to the field of mechanical engineering and can be used when applying artificial roughness on the surface of a part, for example, on straight sections of heat exchangers. A method of obtaining artificial roughness on the surface of a part by a mechanical processing method includes the formation of a surface profile of a part with artificial roughness with a cutting tool. Mechanical processing is carried out on a multi-axis milling machine with numerical control. A roller is used as a cutting tool. Mechanical processing is carried out on a multi-axis milling machine with numerical control. A roller is used as a cutting tool. The part is fixed in a technological fixture, which is installed on the working table of the machine, then it is fed to the machine spindle and a roughness is formed on the surface of the part. The movement of the roller is controlled by the machine spindle.

EFFECT: provides production of artificial roughness in a productive way on metalworking equipment without reducing the quality of the surface layer of the product.
