Thermally induced positioning error modelling and compensation based on thermal characteristic analysis

International Journal of Machine Tools and Manufacture, 2015
Abstract To decrease the thermally induced positioning error of machine tools, a novel approach for modelling and compensation is proposed in this study. The cause of this error is determined to be dynamic pitch error, and its manifestations are discussed in this study.

Thermal Error Modeling of Precision Positioning Stage

Advanced Materials Research, 2013
As the thermal deformation significantly impacts the accuracy of precision positioning stage, it is necessary to realize the thermal error. The thermal deformation of the positioning stage is simulated by the finite element analysis. The relationship between the temperature variation and thermal error is fitted third-order polynomial function whose ...
