摘要

本文提出了一种用三坐标测量机测量非刚性工件时的夹具新方法。新的夹具方法包括主动支架的使用和主动支架的最优位置算法。为了验证所提出的非刚性单元的固定方法，进行了实验和仿真研究。开发的自适应夹具的使用使与引力相互作用有关的误差减少了8倍。自适应夹具方法具有完全的可扩展性，也可用于大尺寸工件的情况。

Adaptive fixturing of non-rigid workpieces for coordinate measurements

The paper presents a new method of fixturing non-rigid workpieces during their measurements using a coordinate measuring machine. The new fixturing method consists in the use of active supports and an algorithm for optimal location of active supports. In order to experimentally verify the proposed method of fixturing non-rigid elements experimental and simulation studies are presented. The use of the developed adaptive fixturing allowed for an eight-fold reduction of the error associated with gravitational interaction. The adaptive fixturing method is fully scalable and can also be used in the case of large-sized workpieces.
