New ICA based thermal error compensation system
Proceedings of the 9th International Conference on Neural Information Processing, 2002. ICONIP '02., 2004Thermal error of machine tools is one of the most significant considerations on machining errors. One of the difficult issues in thermal error compensation system is to select appropriate temperature variables and to obtain accurate thermal error model.

Thermal Sensor Placement Strategy for Machine Error Compensation
Dynamic Systems and Control, 1996Abstract A method was developed to determine the suitable temperature variables for thermal error modeling on a machine structure. An optimality analysis of the best temperature variables is discussed using the analytical solutions of a one-dimensional spindle model.

Thermally induced errors have been significant factors affecting machine tool accuracy. In this paper, the thermal spindle error and thermal feed axis error have been considered, and a measurement/compensation system for thermal error is introduced. Several modelling techniques for thermal errors are also implemented for the thermal error prediction; i.

Neural network-based modelling and error compensation of thermally-induced spindle errors
The International Journal of Advanced Manufacturing Technology, 1996This research is concerned with enhancing the accuracy of a machining centre by compensating for thermally induced spindle errors in real-time. A neural network model was developed for on-line thermal error monitoring. A PC-based error compensation scheme was also developed to upgrade a commercial CNC controller for real-time thermal error compensation
