This paper focuses on a new method for the measurement and correction of positioning errors of the tool centre point (TCP) of machine tools, which can be caused by elastic deformation of the machine structure. In recent years, the application of deformation sensors in machine structures has been examined in detail. The development of suitable mathematical models utilizing the sensor's signals for actual correction methods has proven to be the key challenge. Results of sensor technology and mathematical model development are presented, showing that major positioning errors of machine tools can effectively be corrected. Furthermore, a sensor system has been applied to machine tools in an actual manufacturing environment, proving high potential for future applications.
