Blade inspection has always been a problem in the field of inspection. How to improve the accuracy of blade profile and wheel shape measurement and reduce measurement time has become a problem that various engine manufacturers continue to solve.
The traditional method of inspection is to use special tooling to detect the blades. The disadvantage of this method is low efficiency and poor precision, which affects the detection accuracy and efficiency of the blade. In recent years, with the spread of the coordinate measuring machine, the blade in the detection of the coordinate measuring machine has become a trend.
The three-coordinate measurement uses the spatial Cartesian coordinate system as the reference system to detect the coordinate values ​​of each measured point on the contour of the mechanical part, and processes the data group to obtain the geometrical element size of each part of the part. Its advantages are:
- digitize the measurement object;
-- The measurement accuracy can be improved by error compensation technology, and the measurement accuracy is high;
-- Flexible detection of corresponding parameters by software algorithms;
-- Easy integration of automated measurement and blade design, manufacturing and inspection;
AEH Edward Coordinate Measuring Machine is mainly used for three-dimensional measurement of parts such as cabinets, cams, gears, worm gears and blades in machinery, automobile, aviation and mold industries. Edward Coordinate Measuring Machine has strong measurement function, fault analysis and diagnosis function, which can exchange data with CAD software, and has theoretical CAD digital-analog read-in graphics programming comparison function. The AC-BLAD blade measurement software is a professional software developed by Edwards for the measurement of blades and leaf discs in the aviation field. The blade detection is performed by the V point of the upper and lower edge plates of the blade and the bending point of the blade body in the coordinate system. The perfect combination of Edward Coordinate Measuring Machine and AC-BLAD achieves high precision and repeatability of blade detection, which greatly saves time and improves detection efficiency.
The development of modern blade profile measurement technology depends on the precise measurement requirements of the blade profile. In the face of the performance requirements of future engines, aero-engine blades will develop in the direction of large size, space accumulation and compound bending and twisting, which will put forward higher requirements for blade profile measurement. Therefore, the research focus of blade profile measurement technology is to find out how to quickly and easily acquire the overall shape information of the blade while ensuring high precision, and how to find more high-precision and high-efficiency three-dimensional detection method. The focus is on the complex leaf structure of the whole leaf disc type, and how to obtain the overall shape information of multiple blades with high precision and high efficiency without interference. Edward's blade measurement software and leaf disc measurement software have solved the above technical difficulties and achieved the multi-degree of freedom combined measurement function of the leaf discs, leading the industry.
