This paper deals with a modeling methodology design of an automatic lathe cross slides with plain-bearing in dovetail slides. A proposed rheological model of a slide assembly is based on partial FEM slide models mutually interconnected by linear springs and dampers. The model respects elastic slide assembly mounting onto the machine and a material damping in individual slides. The model verification is based on a comparison of calculated model characteristics with measurement results of a real machine, i.e. with static stiffness, with experimental modal analysis and with measurement of forced vibrations excited by a shaker and cutting forces during machining.
