Abstract: This paper presents the structure, the principle and the designing and calculation method of the micro displacement worktable which has six degrees of freedom. The application of elastic guide and flexible hinge in the micro displacement worktable is described. This type of micro displacement worktable is not only simple in structure but also easy in manufacture. Syn-chronously, the jam caused by the different moving directions of the worktable is avoidable. Therefore, high displacement accuracy can be obtained.

Key words: six degrees of freedom, elastic guide, micro displacement worktable, flexible hinge
