ABSTRACT:
There is provided a method for estimating the thermal displacement of a component of a machine tool comprising the steps of detecting the temperature of at lease one rotatable component of a machine tool having a variable rotational speed and a variable temperature; converting the detected temperature into a numerical value; and estimating the thermal displacement of the component based on the numerical value using an operational expression which includes a time-varying coefficient.
