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 ...

The application of ANFIS prediction models for thermal error compensation on CNC machine tools [PDF]

, 2014
Thermal errors can have significant effects on CNC machine tool accuracy. The errors come from thermal deformations of the machine elements caused by heat sources within the machine structure or from ambient temperature change.

The Thermal Error Estimation of the Machine Tool Spindle Based on Machine Learning

Machines, 2021
Thermal error is one of the main sources of machining error of machine tools. Being a key component of the machine tool, the spindle will generate a lot of heat in the machining process and thereby result in a thermal error of itself.
