| Abstract: | Thermal error of machining center can be estimated by utilizing parameters of electrical current and speed in CNC unit.A mathematical model for thermal deformation of machining center was established by multivariate linear regression.Compared with the model building method based on thermal error,it was more direct for measurement.And the measured data could also be reduced accordingly. |

| Keywords: | machining center thermal error multivariate linear regression heat generating factor transfer function |
