摘要
The casing is one of the key components in the aeroengine. It is a typical complex thin-walled structure, and has the characteristics of large component size, many structural elements, complex profile, huge measurement workload, thin structure and easy deformation, and high precision. The requirements of measuring efficiency and measurement accuracy are getting higher and higher. At present, the three-coordinate measuring machine (CMM) is widely used to measure aeroengine casing in China's aeroengine manufacturers. Taking some casing as an example, CMM is required to measure 256 items, and the measuring period is more than 1 day. In order to reduce the workload and improve the efficient in measuring aeroengine casing, the research develops a multi-axis measuring system based on a high-precision turntable, which has been improved to meet the performance. At the same time, the error of the multi-axis measurement system is discussed to achieve high precision and high efficiency measurement.
