并联机床在加工任务中的主要限制是由于几何变换误差造成的精度低。这些误差的出现是由于集成到控制器中的逆运动学模型的行为与实际PKM的行为之间的差异。本文的目的是分析控制器IKM对PKM加工行为的影响，并量化其对结构元件装配和加工公差的影响。
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.
