...Jian Meng; Dongjun Zhang; Zexiang Li Due to joint clearance, a parallel manipulator’s end-effector exhibits position and orientation (or collectively referred to as pose) errors of various degrees. This paper aims to provide a systematic study of the error analysis problem for a general parallel...

.... This indirect inspection method is in essence an application of the mechanical error analysis of disk cam mechanisms, and the only required measuring instrument is a dial indicator. A pair of conjugate cams were examined by the method and also measured using a CMM to test the accuracy and efficiency...

... on the method. The theoretical error analysis demonstrates that the actuator can achieve low double-digit nanometer actuating accuracy over a long-strike range. Some other advantages, such as fast actuating speed, automatic control, and cost effectiveness, are also expected. Doebelin, E. O., 1976...
