“…Some measuring system were designed to fit the requirements of large components. Pisani et al 82 introduced a intersecting plane technique to achieve a lower measurement uncertainty for a large component with 10 m 3 10 m 3 5 m. Li et al 83 conducted a gravitational straightedge method to measure the flatness of large rail (Figure 5(c)). It has four laser sensors to measure the concrete profile parameters, and a laser profilometer to calculate the maximum difference.…”

The study summarized the characteristics of large board and shaft components. The high-end large machine equipment and clamping devices should be developed in machining for high requirements. Additionally, some non-conventional methods have became a increasing for large components. For measurements, the developing and advanced methods were summarized, and the compensation methods were also complement to realize the high precision and efficiency. If that the component’s size has greatly exceeded the range of the current equipment, the mobile equipment are recommended for machining and measurement, and its detection technology is developed essentially for multiple mobile ones. Thus the study has guiding significance for achieving the high-precision and efficiency machining and measurement for large components, which is a great need in related industries.
