dcterms:description
This paper is a continuation of scientific work on the modeling of highly nonlinear machine tool (MT) thermal errors using thermal transfer functions (TTF). The method is dynamic (uses machine tool thermal history) and its modeling and calculation speed is suitable for real-time applications. The method does not require interventions into the MT structure and uses minimum of additional gauges (just temperature probes placed close to main heat sources). The model solves separately each elements participating on thermal error such as spindle rotation, forced convection, cooling system and environmental temperature influences or impact of machine axes movement which are superposed into resulting description of thermally induced deformations. The paper discusses the development of the robust thermal model of real machine tool (portal milling centre) in detail. Moreover, the model was verified within an action of all above-mentioned influences.
