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 ...

Pre-Compensation of Thermal Error for Laser-Assisted Diamond Turning
Micromachines, 2023 The laser-assisted diamond turning (LADT) method can effectively improve the machinability of hard and brittle materials based on the laser heating effect, resulting in prolonged diamond tool life and better surface integrity. However, due to the incomplete absorption of laser beam energy within the workpiece cutting zone, simultaneous heating of the ...
