Design of a Universal Fixture for Laser Scanning

Abstract

z-axis. A universal fixture using several joints and an adjustable tooling ball holder is designed considering the convenience of the part set-up and the accuracy of the registration. The location of the tooling balls can be arranged to avoid the occlusion of the part and to minimise the registration error. The universal fixture was applied to a wrap-around part having freeform surfaces to demonstrate the effectiveness of the proposed design.
