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

A Priori Error Bound for Moment Matching Approximants of Thermal Models

IEEE Transactions on Components, Packaging and Manufacturing Technology, 2019
This article focuses on the moment matching methodology for deriving dynamic compact thermal models (DCTMs) of electronic components. For the first time, an a priori error bound is theoretically established both in the time and frequency domains, which is suited to accurately estimate the approximation error introduced by DCTMs in practical ...
