Supporting System of a Longitudinal-Milling Machine with a Mobile Gantry

摘要

The dynamic characteristics of the supporting system and the vibrational stability of longitudinal-milling machines may be calculated on the basis of ANSYS software and the methods in [1-4]. A model of the supporting system for the 6675 longitudinal-milling machine is shown in Fig. 1. The dynamic pliability of this supporting system for a symmetric base configuration relative to the gantry and the middle position of the slide is shown in Fig. 2, in the form of the amplitude-frequency characteristic for the dynamic pliability of the structure.
