Adaptive input selection for thermal error compensation models
CIRP Annals, 2020Abstract The presented method selects optimal inputs for compensation models based on the Thermal Adaptive Learning Control methodology. The number of inputs and the individual inputs for each considered thermal error are automatically adapted. The intelligent combination of k-means clustering and Time Series Cluster Kernel enables the approach to ...

Thermal Property Analysis of Precision Machinery and Its Thermal Error Compensation
International Journal of Heat and Technology, 2022The machining error caused by the thermal deformation of machines or tools accounts for half or even more in the total error, and the machining precision could be improved by stabilizing the heat balance of the process system. However, few of the existing studies have concerned about the thermal deformation law caused by the high-speed self-feed ...
