The accuracy and precision of tasks performed by multi-axis machines is profoundly affected by their volumetric accuracy. The volumetric accuracy of a machine depends on numerous factors including geometric and kinematics errors, motion induced errors, deformations of structural members due to static and dynamic loads and thermally induced errors. To alleviate the influence of these factors on the outcome of a task, a passive on-line software compensation method is developed in this paper. The method is based on two components: an interpolation algorithm with shape functions for error prediction, and a recursive on-line software compensation scheme.
