Thermal error modelling for real-time error compensation [PDF]
The International Journal of Advanced Manufacturing Technology, 1996 A modelling strategy for the prediction of both the scalar and the position-dependent thermal error components is presented. Two types of empirical modelling method based on the multiple regression analysis (MRA) and the artificial neural network (ANN) have been proposed for the reaLtime prediction of thermal errors with multiple temperature ...
