? 2022Precision deep-hole parts are widely used in various fields of industrial production. Their machining quality has a significant impact on fatigue limit, geometric accuracy, and stability of products. Since roundness and axis straightness errors are essential technical indexes to evaluate the machining quality of deep-hole parts, their accurate measurement is essential to ensure the performance of related products. In this study, a multi-sensor integrated system that can measure two kinds of shape errors simultaneously was developed based on laser displacement sensor, circular grating, two-dimensional position-sensitive detector (PSD) and laser interferometer. It is suitable for deep-hole parts with a diameter of 150–165 mm and a length of 600–20000 mm. Furthermore, the uncertainty analysis models of roundness and axis straightness errors for this system were constructed. Eventually, the effectiveness of the measurement system was successfully verified through experiments.
