To compensate for thermal errors in machine tools, strategic sensor placement and rapid error calculation are crucial. This study addresses these challenges using model order reduction. A transfer function matrix and a sensitivity function were defined to optimize the number and locations of sensors without physically attaching them to the machine tool. This methodology was validated through experiments on a 3-axis machining center. The number of sensors was reduced by 50 %, and the calculations were performed instantaneously on a laptop. These results demonstrate the approach's effectiveness in advancing sensor placement strategies and real-time thermal displacement estimation. [Display omitted] • Developed sensor placement strategy for machine tools. • Reduced computation time for thermal error estimation. • Used transfer function matrix and sensitivity function. • Transfer function matrix was consistent with machine tool structure. • Thermal displacement could be estimated instantaneously without loss of accuracy.
