Application Study of the Aviation Structures’ Machining Deformation On-Line Measurement Technology

Based on non-contact 3-D on-line measurement technology, the article studies the aviation structures’ machining deformation on-line measurement technology. The technology provide a effective way to measure the machining deformation, and the accuracy of the system can reach 0.05mm in 2000mm. Use the on-line measurement technology to get the 3-D shape of the structures after machining, and then compare the measurement result with the theoretical model to get the machining deformation. The deformation results provide the basis for the improvement of machining process.
