Dynamic revising method of three-coordinate measuring machine

Abstract

The invention relates to a dynamic revising method of a three-coordinate measuring machine, and the method comprises: displacement measuring devices are respectively arranged at the side of the two parallel Y-axial guide rails of the three-coordinate measuring machine; when the measurement is carried out by the three-coordinate measuring machine, the displacement measuring devices respectively obtain the data of the two displacements of an X-axial movement beam on the Y-axial guide rails and the displacement measuring device on the X-axial movement beam also synchronously obtains the data of the displacement of a measuring probe on the X-axial movement beam; and the calculation is carried out through the three-coordinate measuring machine according to the data of the three displacements to obtain the real-time displacement data of the measuring probe on a Y-axial guide plane. The dynamic revising method of the three-coordinate measuring machine provided by the invention has the advantages of reasonable design and low application cost, can be suitable for the improvement of the existing three-coordinate measuring machine and the manufacture of a new three-coordinate measuring machine, and can be used for effectively eliminating the influence of Abbe errors on the measuring result and also effectively improving the speed and efficiency of the measurement.

Problems solved by technology

However, due to the existence of the Abbe error, this type of three-coordinate measuring machine must first reduce the displacement speed of the measuring machine when measuring the product, thereby reducing the angular swing of the X-axis beam and reducing the Abbe error, and then measure, resulting in The measurement speed is slow and the efficiency is low
