Abstract: An on-line modified or modeling method of thermal error
compensation model for CNC machines is presented. The resulting model is
not a fixed formular, but an algorithm consisting of some simple
recursive equations. The thermal error compensation model is modified
recursively according to new input data. Since the recursive algorithm
no longer uses the former data, the process is very rapid and simple. The
result of proposed modeling method indicates that it can highly improve
the robustness, versatility and precision of the thermal error
compensation model.
