RESEARCH OF OSCILLATIONS DURING END-MILLING AND THEIR INFLUENCE ON THE FORMATION OF THE MACHINED SURFACE

Purpose. Study of oscillations that occur during end-milling and their influence on the formation processed surface.
 Research methods. The research was carried out using experimental method, in which oscillograms part were recorded with allocation cutting time milling. Basic fragments studied analytical parameters characterizing milling process measured, relationship surface determined.
 Results. When low spindle rotation frequencies, down up direction feed, is affected by various types oscillations, are characteristic first second speed zones oscillations. During end-milling, only forced operate high-speed oscillation zone. In zone milling, accompanying natural vibrations technological system superimposed It has been experimentally analytically proven resulting deviation from position elastic equilibrium wave affects pitch height waviness surface, confirms connection between dynamics shaping.
 Scientific novelty. impact free evaluated end-milling.
 Practical value. obtained results prove amplitude provide an opportunity to choose modes ensure vibration stability
