Neural network-based modelling and error compensation of thermally-induced spindle errors

The International Journal of Advanced Manufacturing Technology, 1996
This 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
