Cutting data effect on machine tool vibrational state and surface roughness when machining

Abstract

The article is devoted to the study of vibration processes of metal-removal equipment. In the course of the study, the dynamic phenomena arising in the metal processing in this complex dynamic system have been investigated for the purpose of further control of cutting modes that minimize the accompanying oscillations and vibrations. This article presents the results of studying the dependence of the roughness parameters on the vibration of the spindle assembly and processing modes in the milling operation. Planning techniques and experimental statistic were used in our investigation. The dependence of vibration acceleration root-mean square parameters (RMS parameters) on cutting set modes was determined. Monitoring of vibration parameters when machining centres operating allows improving the quality of parts processing and preventing expensive machine operating under dangerous dynamic load.
