Abstract: The present invention provides a method for shape error in-situ measurement of toruses, and is realized based on a system for shape error in-situ measurement of large-scale toruses. The system for in-situ measurement comprises an attitude adjusting part, a rotating part and a measuring part. The attitude adjusting part comprises an attitude adjusting platform, an attitude adjusting platform motor and an adapter panel; the rotating part comprises a rotating index plate base and a high-precision rotating index plate; and the measuring part comprises a sensor clamp, sensor holders, contact sensors and associated equipment. The present invention realizes the application of the three-point method in shape error measurement of the torus, also realizes algorithm improvement of the three-point method in realizing shape error in-situ measurement of the torus, can realize shape error in-situ measurement of the torus, can greatly reduce the processing time of the part and can reduce the influence of repeated clamping on part precision.
