摘要：
In order to improve the measurement efficiency and accuracy of the overall blisk by CMM and to solve the problems that large-sized blisk exceeded the measuring range of measuring machine, a six-axis measurement system was constructed based on CMM and a high-precision turntable. According to the principle of space coordinate transformation, a mathematical model of the turntable coordinate system and the blisk workpiccc coordinate system were established. A space error compensation method was proposed after the coordinate systems of different blades of the blisk rotated with the turntable. Test results show that the measurement efficiency increases by 28.22% on average under the premise of ensuring that the measurement accuracy of each blade profile parameter meets the process requirements. Compared with the measurement data without the turntable, the new six-axis measurement system measures the horizontal blisk blade profile, and the profile comparison errors are almost all within 0.008 mm. The maximum comparison error is less than 0.015 mm, which is smaller and more stable than the measurement errors of the inclined blisk. © 2023 China Mechanical Engineering Magazine Office.
