摘要

Background

The alignment measurement of the High-Energy Photon Source (HEPS) involves intricate requirements for wire position measurement, metal sheet edge monitoring, and precision verification of visual scanning equipment.

Methods

This study proposes a composite three-coordinate measurement system using both contact and non-contact probes in a collaborative approach. The image probe and contact probe work together to maximize complementary strengths; when applied to deformable components, highly reflective surfaces, and complex geometric features, this method effectively mitigates the limitations of traditional single-probe systems.

Results

Experimental results demonstrate that the composite system achieves a combined standard uncertainty of 11.7 μm in various applications, including determining the magnetic center of a rotating coil, adjusting the aperture blade toward a mechanical origin, and validating scanner accuracy within taut wire systems. Additionally, the use of adjustable slit blades in beamline stations reduces adjustment time to 0.25 h, a fourfold increase in efficiency.

Conclusions

The collaborative operation of the two types of probes on a three-coordinate measuring machine enhances the efficiency and reliability of alignment measurement tasks, thus satisfying the alignment measurement requirements of the High-Energy Photon Source (HEPS).
