Analysis of Motion Errors of Linear Guide Pair Based on Parallel Mechanism

This paper systematically summarized the technical state of art and research results on motion error a linear guideway, corrected some misconceptions, further clarified relationship between straightness guide rail itself stage. Moreover, new method based parallel mechanism is provided to study errors pair. The basic idea abstract structural stage into 4-bar mechanism. Thus, can be considered as moving platform in Its analysis also transferred position angular analyzed simultaneously by using theory Some experiments were conducted guideway self-developed coordinate measuring machine. experimental data verify feasibility correctness this method.
