Abstract
Based on the theory of laser measurement, a novel laser-based system to measure the thread profile of ballscrew has been proposed, which integrates the triangulation laser measuring system and the dual-axis rotary stage. The proposed system is made of the laser-based measuring unit to detect the longitudinal section of the thread profile and the dual-axis rotary stage for the movement of the undetected object. The experimental results show that the parameters of the measurements for the threaded gauge are in the tolerance range. Moreover, the measurement errors of this non-contact measuring technique are analyzed by the comparison between the proposed system and the coordinate measuring machine (CMM) system. The maximum error band of the measurements for the screw and the nut is about 4 and 4.5 μm, respectively. ? 2010 Elsevier Ltd.
