In this paper, the influence of friction on static, dynamic characteristics, the strength and lifetime of a 3-axes flexible CNC machine tool are taken into account. The machine tool is first modelled by using finite element method (FEM) to perform static structural analysis. After that, the dynamic effects caused by the inertia forces and the displacement of moving part of the machine on contact stress are considered in this study. Then, the stress and contact force distributions on solid-flexible contact are also obtained. Finally, the influence of dynamic structure, cutting conditions and material properties on strength and lifetime of CNC machine tool are discussed by using fatigue analysis. Consequently, the proposed method can be used for efficient simulation of structural dynamics, lifetime assessment as well as interactions of the real CNC machine with the machine tool structure in a virtual environment.

Abstract This study uses various dynamic models to predict contact forces in a finger-follower-type cam-valve system. It is found that the following factors have the greatest impact on the overall behavior of a cam valve system. They are the cam profile, valve spring, and rocker arm ratio. In this study, different techniques in modeling cam profiles are explored. Various ways of modeling valve-springs are examined. The rocker-arm ratio is assumed to be either a nonlinear function or a constant. Since the speed of the cam dictates a great deal in the overall behavior of the system, three different cam speeds are tested in this study. The models used in this study are established with a constructive approach by using a commercially available software system.
