Abstract:
This paper stated the applicat ion of parallel link mechanism in modern machine tools, set up the error analysis as to parallel link mechanism in the v irtuca-l ax is machine tool, derived the double t riangular error equat ions of parallel link mechanicsm in its horizontal posture, analy zed the linearity and non-sing ularity of the error equat ions, thus g iving the normal splution to the horizontal posture error. T he error dist ribution law is simulated as to the center line in the workplace, and the error distribut ion curves are draw n as well.
