Dynamics of the guideway system founded on casting compound

Abstract

The work presents a new technology for the assembly of ball guideway systems which involves the use of a thin layer of a casting compound. The experimentally verified simulation research presented in the work indicates that the use of the casting compound between the guide rail and the bed of the machine tool positively influences the dynamics of the system. The paper is concerned with the comparison between the new solution with the guide rail assembly technology presently in use on the basis of a guideway system consisting of a body and a milling table. The dynamics was compared with the use of a frequency response function which had been determined in an impulse test. The proposed solution is characterised by a higher dynamic stiffness, which may directly influence the precision of the machined surfaces. © 2011 The Author(s).
