Abstract
With the continuous improvement of product quality requirements in modern manufacturing industry, the high-precision measurement of mechanical parts has become the key link to ensure product performance and reliability. This study aims to propose a comprehensive measurement method based on multi-sensor fusion and intelligent error compensation for the high-precision measurement of mechanical components of complex geometric shapes. The research first analyzes the limitations of traditional measurement technology in the face of complex surfaces and tiny features, such as insufficient measurement accuracy, low data processing efficiency and other problems, and defines the research ob jectives based on the current development trend of intelligent manufacturing. To achieve this goal, this paper designs a set of multimodal measurement system integrating optical scanning, contact probe and non-contact laser ranging, which significantly improves the adaptability and accuracy of the measurement system by optimizing the sensor configuration and data acquisition strategy.
