INTERACTION OF SPATIAL OSCILLATION WITH ROUGHNESS OF SURFACE WORKED BY EXAMPLE OF TURNING

The work purpose is to determine the impact of cutter spatial oscillation upon parameters and values of worked surface roughness, in particular, the paper is dedicated to the definition of differences in roughness parameters depending on a projecting plane in which cutter oscillation is considered. There are considered the matters of the impact of cutter spatial oscillation upon roughness of the surface worked, and also cutting parameters influencing the intensity and frequency of oscillation of cutter point oscillation. The solution of the problems specified is carried out on the basis of the analysis of data published in scientific literature and experimental data obtained in the course of investigations. The novelty of the work: it is revealed that a dynamic state of the technological system for machining which depends upon a multitude of factors has an influence not only upon a value of surface roughness, but also upon its parameter. Conclusion: surface roughness depends upon relative oscillation processes of the part under machining and a tool cutting edge in the working space caused mainly by a process of chip formation.
