EN Purpose: The development of precision machine tools requires modelling, simulation and optimization, especially the accurate modelling of machine tool thermal behaviour aimed at improving the machine tool design. Design/methodology/approach: This paper discusses machine tool design improvement based on thermal behaviour modelling and the complexities involved. A highly accurate thermal model of the HSC machine tool is presented and the necessity of including the whole complex of factors affecting machine tool behaviour and error compensation is highlighted. Modelling problems are illustrated with examples of accurate modelling and simulation of machine tool behaviour, aimed at minimizing thermal disturbances in machining precision. Findings: The precise modelling of HSC machine tools dynamic spindle displacement during a change of rotational speed. Research limitations/implications: The transitional states of spindle speed changes are very complex and difficult to precise recognition. Practical implications: The need of integrated complex modelling of precise HSC machine tools thermal behaviour. Originality/value: All models used for machine tool behaviour simulation are fully original.
