| Abstract: | The temperature field and the thermal error for the spindle of machining center have been measured by five-spot method. A linear regression model between the temperature changes and the thermal error for the spindle has been built up by partial least-squares regression method. By computation and analysis, this model is provided with good forecast abihty and enough precision. |
