“…Given that the twist angle varies along the blade, therefore for 2D investigation, the blade is cut into few sections, as shown in Figure 7. Makem et al [41] defined the similar phenomenon as twist deviation. Figure 6 shows the coordinate system of the blade and to ensure correct measurement, both blade and measurement equipment coordinate system must be the same.…”

Geometrical defect is one of the main problems that will affect performance and perfect mating of produced parts. Coordinate measurement machine (CMM) is commonly used for the measurement, but the use of this machine is limited because of the small size and complexity of the component or features. This study aims to evaluate the defect that occurs on an AA6061 cold forging blade produced using cold forging process based on profile measurement technique. A systematic approach based on focus variation was proposed to evaluate two features, that is, roundness error and twist deviation. The profile was obtained with the use of InfiniteFocus Alicona 3D surface measurement system. Specific algorithms were developed for different cases as the evaluation of the features is discrete and the results were validated.

“…In most cases, the Finite Element Method (FEM) has been utilized to predict the springback. For example, Makem et al (2008) proposed a virtual inspection method for the measurement of twist angle deviation using FEM and CMM. In their approach, a number of points on the surface of the blade were selected and measurements of the twist angle error were made based of the profile deviation before and after forging.…”

Geometrical defects that are attributable to springback are among the major defects induced by the sheet metal forming process. Such defects are critical for sections with varying thickness, such as Autonomous Underwater Vehicle (AUV) propeller blades. In this study, the springback in the twist-bending of an AA6061 propeller blade was quantified by comparing the targeted and manufactured profiles obtained using the commercial threedimensional surface measurement technique. The results show that the twist springback becomes larger as the twist angle increases. Similarly, the twist springback increases with increasing deformation ratio.

“…For the measurement methods of the profiles of aero-engine blades, they can be broadly categorized into two types: contact measurement and non-contact measurement. Contact measurement typically refers to methods that use physical contact means to obtain surface data from the blades, with the most typical example being Coordinate Measuring Machines (CMMs) [8,9]. This type of method's main advantage lies in its high precision and reliability.…”

The aero-engine serves as the “heart” of an aircraft and is a primary factor determining the aircraft’s performance. Among the crucial components in the core of aero-engines, aero-engine compressor blades stand out as extremely important. They are not only numerous but also characterized by a multitude of parameters, making them the most complex parts in an aero-engine. This paper aims to address the trade-off between accuracy and efficiency in the existing measurement methods for asymmetric blades. Non-contact measurements were conducted using a structured light system composed of a stereo camera and a DLC projector. The point cloud data of the blades are processed using methods such as the PCA (Principal Component Analysis) algorithm, binary search, and least squares fitting. This paper established a fringe-projection profilometry light sensor system for the multi-view measurement of the blades. High-precision rotary tables are utilized to rotate and extract complete spatial point cloud data of aviation blades. Finally, measurements and comparative experiments on the blade body are conducted. The obtained blade point cloud data undergo sorting and denoising processes, resulting in improved measurement accuracy. The measurement error of the blade chord length is 0.001%, the measurement error of blade maximum thickness is 0.895%, compared to CMM (Coordinate Measuring Machine), where the measurement error of chord is 0.06%.
