Virtual Sensor for Calibration of Thermal Models of Machine Tools [PDF]

Advances in Artificial Neural Systems, 2014
Machine tools are important parts of high-complex industrial manufacturing. Thus, the end product quality strictly depends on the accuracy of these machines, but they are prone to deformation caused by their own heat. The deformation needs to be compensated in order to assure accurate production.
