In this study, we analyzed it about the motion error of High precision MC. We used a simulation model and the measurement result of the machine for analysis. High precision MC has the friction-less drive system that combined a hydro static guide way with linear motor drive. In addition, the motion error measured the relative displacement on the X-Y plane between the spindle-table by a grid encoder and we used the Offset-Path Method to do and calculated it. As a result. 1. In a diamond-shaped command trajectory, a motion error to produce by the dynamic-characteristic difference between the axis was confirmed at the corner. 2. We confirmed a motion error at the corner part like the experiment results by simulation. In the case of the velocity-loop proportional gain setting that synchronized the difference in dynamic-characteristic difference, the motion error to be caused by the difference in dynamic characteristics was not seen.
