Description
  • This paper introduces an advanced modelling of thermally induced displacements based on thermal transfer functions (TTF). The model employs a combination of different inputs, temperature sensors placed on the machine tool structure, and rotational spindle speed. A mathematical model using TTF was implemented into a standard CNC controller of horizontal milling center to compensate for thermal errors in real time. It was achieved a reduction of thermal errors of more than 75% of the initial value in various working cycles. Moreover, the results of the TTF model were compared with 2 models obtained via MLR as a case study.
