- •
The thermal error transfer function of a workpiece considering the influence of environment temperature is established.
- •
The thermal error transfer function of the machine tools is built using the principle of dimension chain and the thermal error transfer function.
- •
Thermal error transfer function in in time domain and frequency domain is implemented to analyze the thermal characteristics of machine tool.
- •
The thermal error model structure is determined according to the thermal error dimension chain, which can save time in identifying structure parameters of thermal error transfer function.
