The paper describes a modelling technique of tool rest of modern machining centre with focus at damping of dovetail groove slideway. Damping of tool rest structure strongly affects the stability of machining process, which must be maintained at wide range of machining condition, thus the adequate model of such damping should respect its physical origin to enable realistic estimation of boundaries between stable regions and self-excited vibrations at design stage of a new machine. Presented model of tool rest comprises damping characteristics obtained by HDL analysis of oil film of dovetail groove.
