Abstract

The deviation of deep hole’s axis is measured in real-time machining process by using ultrasonic thickness measurement method. A ultrasonic device is designed using 3-points circle method, the polar parameter model of measurement objects is built and the function relationship between object and measured data is established. Grubbs criteria is used to remove the gross error of data aim to the unstable of online measurement. Using error limits is raised to estimate measuring error. It is verified by actual measurement that this method can measure the deviation and its direction of deep hole’s axis accurately in real-time machining process and the measurement error can be controlled under the 2 times of single probe error.
