    Machining technology is developed with increasing flexibility to adapt to the rapid changes of the market. Parallel kinematic machines (PKMs)have demonstrated great flexibility to suit the demands, but it is still not possible to achieve as high accuracy as the traditional NC machines (TNCMs).This paper presents a general review on the structure-based errors of PKMs incomparison with TNCMs to reveal the root causes of the errors and their relevance to the machining uncertainty. The geometric/kinematic, gravitational,and thermal aspects in both TNCMs and PKMs are identified as structure-based error sources. Errors in each aspect are comparatively analyzed, and inherent differences are found to bring new challenges to the accuracy of PKMs. Finally,perspectives in each aspect are highlighted for accuracy improvement of PKMs.
