indeterminate error

For the sub-6-degree of freedom(DOF)parallel kinematic machines(PKM),it is necessary to separate the geometric error sources which influence the compensable and uncompensable errors of the mobile platform by error modeling,so as to supervise the accuracy design and kinematics calibration.

对于少自由度并联构型装备,必须通过误差建模将影响末端可控和不可控误差的几何误差源进行分离,从而指导机构的精度设计和运动学标定。
