摘要
A machine tool, e.g., of large dimensions, comprises a j bench (2), an upright base (4), control means of the translation of the upright base, an upright base position sensor comprising an optical line or linear encoder (20) fixed to the bench (2), means for detecting the temperature (T1,...,Tn) of the optical line and management means (30) for processing the temperature signals coming from the optical line temperature detection means and the signals of the upright base translation control means to determine a correction signal for the upright base translation control means according to at least one temperature detected along the optical line.
