In order to improve the qualification rate of aircraft engine impellers, an aircraft manufacturing company entrusted HOLON 3D to provide a production inspection solution for the aircraft engine impellers they produced. Since aircraft impellers are prone to deformation during production, the customer needs to obtain high-precision three-dimensional data to compare with the original digital model. Analyze and detect product processing efficiency and pass rate to improve product quality.

Facing problems

1. The aircraft engine impeller is small in size, has a complex overall outline, and has many shadows in the dead corners of the impeller components. Customers need to accurately measure the overall three-dimensional data of the components and require very high accuracy. Traditional measurement methods cannot accurately and quickly measure the impeller arc surface data, which is difficult for complex impellers. There is no effective measurement plan for the contours and dead center shadows, which discourages peers.

2. The customer considers that the company will use it later to save time and human resources, and requires a high-precision and high-efficiency inspection solution. Powder spraying is not allowed for inspection of finished workpieces. The impeller is a metal reflective part, which brings another big problem to scanning inspection.

Solution

Product features: Model 29 is a portable blue-ray handheld 3D scanner independently developed and produced by HOLON 3D. It has the following advantages:

◆ Ultra-portable, the body weight is only 0.92kg;

◆ Accuracy up to 0.020mm, resolution up to 0.020mm;

◆ Blue light laser: suitable for measurement tasks in various complex environments such as indoors and outdoors, and has stronger anti-interference ability;

◆ High-speed scanning: 1,370,000 measurements/second;

◆ It has large measurement space and good stability, and a single machine can complete the measurement of extremely large workpieces;

◆ Almost unlimited 3D scanning, not affected by object size, material, color, etc., no need for powder spraying.

The engine impeller is one of the important parts of the aircraft, so its quality control is particularly important. HOLON 3D technical engineers quickly acquired high-precision three-dimensional data through the industrial-grade handheld three-dimensional scanner Model 29, imported the three-dimensional data of the impeller into the three-dimensional detection software to generate a three-dimensional data chromatogram, and compared and analyzed it with the original digital model to detect whether the aircraft engine impeller is qualified. , successfully solved the quality problems of product production and provided accurate data support for the secondary design of aircraft engine impellers.
