Chatter Behavior of Heavy Machine Tools

Abstract

Based upon the theory of regenerative chatter the system machine-tool - cutting process is reduced to a nonintermeshed closed control loop, of which the stability behavior is representative for the chatterfree cutting performance. For economically carrying out the stability analysis digital computer programs have been developed. Results of practical chatter investigations are finally detailed. Methods and digital computer programs have been developed and tested for the precalculation of the static and dynamic properties of machine tool systems already in the status of design. A short general view over this research work is presented. For calculating the deformation of columns with square and rectangular cross-section equations have been derived. They include the influence of shear force and a cross-sectional distortion under torsional loads can be considered as well. In model tests these equations have been proved.
