The knowledge of thermo-elastic tool center point (TCP) errors offers significant potential to increase the achievable product quality in manufacturing. This paper presents a novel, cost-effective, machine integrated measurement method for small and medium sized machine tools to detect thermally induced errors utilizing a position sensing detector (PSD) and a thermo-stable laser frame. Based on the measured output of the developed system, 13 of 21 errors of a three-axis kinematic can be derived. Furthermore, the error-specific uncertainties are evaluated by means of Monte Carlo method. Experimental results are presented and give an impression of the capability of the measurement method.
