The geometric parameters of the capillary-porous structure in the form of microfinning  are the main factor determining the operational characteristics of the heat pipe. In this work, we  studied the deviation of the shape of the obtained microfinning in the manufacture of capillary-porous structures of a heat pipe from various materials by the method of deforming cutting. The experiment was carried out on a screw-cutting lathe with the help of a fixture - a roller, which has the possibility of fixing and tensioning the processed strip. Photos are obtained of thin sections of finned capillary-porous structure from various materials obtained by deformation cutting with different feeds. The theoretical profile is calculated and the obtained forms of capillary structures are compared at various finning steps.
