The implementation of the damping system to reduce vibration milling setup

Abstract

The empirical method and the dependence of parameters of cutting modes and the degree of influence on the magnitude of vibration in the processing of curved surfaces parts using non-rigid milling system. On the basis of experimental data compiled diagram describing the desired relationship, a technique to identify the optimal cutting force for the purpose of minimizing fluctuations in the technological system. The dependence of RMS value acceleration on the machining center spindle from cutting speed defined. The dependence of significant influence of a single radial beat of the tooth of the tool to the maximum value of vibration speed defined. The proposed method of reducing the elastic strain of tool adjustment in machining milling machining centers with CNC. The necessary conditions for the effective application of the damping elements and requirements included in the milling system for implementation of the strategy of reducing the magnitude of the vibration modes corresponding to high-speed milling of difficult to machine materials are determined. The amplitude values of the frequency characteristics of the operating mode depending on the feed rate and depth of cut investigated. Were subjected to analysis of vibration parameters at different values of cutting speed in hard materials, the result was determined by the procedure of justification of the preferred frequency of rotation of spindle Assembly in the process of finishing.
