Accuracy evaluation device and accuracy evaluation method

摘要

PROBLEM TO BE SOLVED: To easily grasp an error with respect to a design reference position. An accuracy evaluation device (10) that evaluates the accuracy of a joint portion when first and second parts are joined to each other via a first and second joint surfaces is in advance with design data of the first and second parts. The data acquisition unit 15 that acquires the measured measurement data of the first and second parts and the design data and the measurement data are set at the same positions on the first and second joint surfaces in terms of design. The error calculation unit 16 that calculates the error between the design data of the design reference point and the measurement data at the first and second reference points on the first and second coupling surfaces corresponding to the design reference point, the design reference point and the first , The interference degree calculation unit 17 that calculates the degree of interference at the design reference point at the time of joining the first and second parts based on the error from the second reference point, and the design of the first and second parts based on the design data. A display unit 14 that displays the model and superimposes an image showing the degree of interference on the position of the design reference point of the design model is provided.
