Abstract: Joint interface property is of great importance to the whole machine tool behaviour, especially for mechanical and thermal behaviour. Traditionally, studies of mechanical joint interface focus on mechanical behaviour or thermal behaviour separately, while in fact they couple tightly. By studying thermal contact resistance and thermo-mechanical coupled mechanism on fixed joint interface, a model considering thermo-mechanical coupled effect is presented in this paper. Compared with experimental data in specimens and high-speed motorised spindle, accuracy is verified on this modelling method. This would be useful to construct a precise model of the whole machine tools.
