For application of the LM measurement device proposed in our first report which has a high measurement accuracy throughout the working sphere, it is necessary to identify the errors of the LM device itself and compensate for the influence of these errors on the measurement results. In this paper, a simple and practical identification method for this purpose is developed. First, an accurate model containing the effects of the mechanism and the sensor errors in the LM measurement instrument is developed and a simple approximation equation with sufficient accuracy for application is derived from this model. Next, the identification method is proposed based on the approximation equation. The experimental results of identification and measurement for several motion trajectories with a machining center are shown. The validity of the proposed method is well confirmed by these results.
