Abstract
The paper deals with a geometrical model of the wear mechanism initiation
according to the macroroughness tops radii R, the rnicroroughness peaks radii r,
and their inclination angle h, in relation to the friction element movement
direction. It was found that kinematic apparent self-sharpening some surface
roughness tops occurs according to a physical phenomenon during the oblique
cutting process. Experimentally carried out validation of the wear mechanism
initiation was in good agreement with theoretical assumptions and analyses. The
mechanism developed is explained in light of the geometrical structure of
friction surfaces with the determined frictional properties, both in technology and
nature. Analysis of the conditions affecting chip formation start-point initiation
allow us to give guidelines to minirnise initiation friction surfaces geo
