“…For the high-precision large-scale components, such as large bearings and gears, several quality features have to comply with tolerances in the range of 20–50 mm. As shown in Figure 5(a), Shang et al 2 firstly conducted a comprehensive investigation on the 3D shape measurement methods of large-scale complex surfaces, including the basic principles, application scope, measurement instruments, and then discussed the tasks and challenges in the current methods, and finally provided potential solutions. Jin et al 81 reviewed and summarized the monitoring methods of slewing bearings for large-scale wind turbine generator system (Figure 5(b)).…”

“…1 Thus, the machining, measurement, and other key technologies of large and complex components are prior in the key development areas of the machining industry. 2 Actually for different components, the large size is only a relative concept, and has different size ranges. Taking a large aircraft component for example, the size of supercritical wing can be as large as tens of meters.…”

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.

“…There are many methods for threedimensional shape reconstruction of complex surface shapes [1][2][3][4][5][6][7]. The traditional methods, such as Fourier transform profilometry (FTP) [1,2] and phase measurement profilometry (PMP) [3,4], which have been widely used in many fields, such as industrial detection, biomedicine and physical profiling, because these methods are non-contact measurement based on structural light projection and have high accuracy [8].…”

The precise three-dimensional measurement of fuel nozzles is of great significance to assess the manufacturing accuracy and improve the spray and atomization performance. This paper proposes an improved fast shape from focus (SFF) method for three-dimensional measurement of key features of fuel nozzles. In order to ensure the measurement accuracy and efficiency of the SFF, the dispersion of the measured points from a standard flat plane was used to select the optimal combination of the focus measure operator, window size and sampling step size. In addition, an approximate method for the focus measure interval is proposed to improve the measurement efficiency, which uses the peak region of the central pixel to replace the peak region of other pixels. The results show that the proposed method decreased the average computation time of the focus measure by 79.19% for the cone section and by 38.30% for the swirl slot. Compared with a reference laser scanning microscope, the measurement error in length is within 10 μm and the error in angle is within a maximum 0.15°.
