摘要：
A main limitation of parallel kinematics machine tools in machining tasks is their accuracy low level largely due to geometrical transformation errors. These errors appear due to the difference between the behaviour of the inverse kinematics model integrated into the controller and that of the real PKM. The aim of this paper is to analyse the influence of the controller IKM on PKM machining behaviour and to quantify its incidence on the assembly and machining tolerances of structural elements.
